-Using Creative Commons Public Licenses
-
-Creative Commons public licenses provide a standard set of terms and
-conditions that creators and other rights holders may use to share
-original works of authorship and other material subject to copyright
-and certain other rights specified in the public license below. The
-following considerations are for informational purposes only, are not
-exhaustive, and do not form part of our licenses.
-
-     Considerations for licensors: Our public licenses are
-     intended for use by those authorized to give the public
-     permission to use material in ways otherwise restricted by
-     copyright and certain other rights. Our licenses are
-     irrevocable. Licensors should read and understand the terms
-     and conditions of the license they choose before applying it.
-     Licensors should also secure all rights necessary before
-     applying our licenses so that the public can reuse the
-     material as expected. Licensors should clearly mark any
-     material not subject to the license. This includes other CC-
-     licensed material, or material used under an exception or
-     limitation to copyright. More considerations for licensors:

-
-     Considerations for the public: By using one of our public
-     licenses, a licensor grants the public permission to use the
-     licensed material under specified terms and conditions. If
-     the licensor's permission is not necessary for any reason--for
-     example, because of any applicable exception or limitation to
-     copyright--then that use is not regulated by the license. Our
-     licenses grant only permissions under copyright and certain
-     other rights that a licensor has authority to grant. Use of
-     the licensed material may still be restricted for other
-     reasons, including because others have copyright or other
-     rights in the material. A licensor may make special requests,
-     such as asking that all changes be marked or described.
-     Although not required by our licenses, you are encouraged to
-     respect those requests where reasonable. More considerations
-     for the public:

-Section 2 -- Scope.
-
-  a. License grant.
-
-       1. Subject to the terms and conditions of this Public License,
-          the Licensor hereby grants You a worldwide, royalty-free,
-          non-sublicensable, non-exclusive, irrevocable license to
-          exercise the Licensed Rights in the Licensed Material to:
-
-            a. reproduce and Share the Licensed Material, in whole or
-               in part; and
-
-            b. produce, reproduce, and Share Adapted Material.
-
-       2. Exceptions and Limitations. For the avoidance of doubt, where
-          Exceptions and Limitations apply to Your use, this Public
-          License does not apply, and You do not need to comply with
-          its terms and conditions.
-
-       3. Term. The term of this Public License is specified in Section
-          6(a).
-
-       4. Media and formats; technical modifications allowed. The
-          Licensor authorizes You to exercise the Licensed Rights in
-          all media and formats whether now known or hereafter created,
-          and to make technical modifications necessary to do so. The
-          Licensor waives and/or agrees not to assert any right or
-          authority to forbid You from making technical modifications
-          necessary to exercise the Licensed Rights, including
-          technical modifications necessary to circumvent Effective
-          Technological Measures. For purposes of this Public License,
-          simply making modifications authorized by this Section 2(a)
-          (4) never produces Adapted Material.
-
-       5. Downstream recipients.
-
-            a. Offer from the Licensor -- Licensed Material. Every
-               recipient of the Licensed Material automatically
-               receives an offer from the Licensor to exercise the
-               Licensed Rights under the terms and conditions of this
-               Public License.
-
-            b. Additional offer from the Licensor -- Adapted Material.
-               Every recipient of Adapted Material from You
-               automatically receives an offer from the Licensor to
-               exercise the Licensed Rights in the Adapted Material
-               under the conditions of the Adapter's License You apply.
-
-            c. No downstream restrictions. You may not offer or impose
-               any additional or different terms or conditions on, or
-               apply any Effective Technological Measures to, the
-               Licensed Material if doing so restricts exercise of the
-               Licensed Rights by any recipient of the Licensed
-               Material.
-
-       6. No endorsement. Nothing in this Public License constitutes or
-          may be construed as permission to assert or imply that You
-          are, or that Your use of the Licensed Material is, connected
-          with, or sponsored, endorsed, or granted official status by,
-          the Licensor or others designated to receive attribution as
-          provided in Section 3(a)(1)(A)(i).
-
-  b. Other rights.
-
-       1. Moral rights, such as the right of integrity, are not
-          licensed under this Public License, nor are publicity,
-          privacy, and/or other similar personality rights; however, to
-          the extent possible, the Licensor waives and/or agrees not to
-          assert any such rights held by the Licensor to the limited
-          extent necessary to allow You to exercise the Licensed
-          Rights, but not otherwise.
-
-       2. Patent and trademark rights are not licensed under this
-          Public License.
-
-       3. To the extent possible, the Licensor waives any right to
-          collect royalties from You for the exercise of the Licensed
-          Rights, whether directly or through a collecting society
-          under any voluntary or waivable statutory or compulsory
-          licensing scheme. In all other cases the Licensor expressly
-          reserves any right to collect such royalties.
-
-
-Section 3 -- License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-  a. Attribution.
-
-       1. If You Share the Licensed Material (including in modified
-          form), You must:
-
-            a. retain the following if it is supplied by the Licensor
-               with the Licensed Material:
-
-                 i. identification of the creator(s) of the Licensed
-                    Material and any others designated to receive
-                    attribution, in any reasonable manner requested by
-                    the Licensor (including by pseudonym if
-                    designated);
-
-                ii. a copyright notice;
-
-               iii. a notice that refers to this Public License;
-
-                iv. a notice that refers to the disclaimer of
-                    warranties;
-
-                 v. a URI or hyperlink to the Licensed Material to the
-                    extent reasonably practicable;
-
-            b. indicate if You modified the Licensed Material and
-               retain an indication of any previous modifications; and
-
-            c. indicate the Licensed Material is licensed under this
-               Public License, and include the text of, or the URI or
-               hyperlink to, this Public License.
-
-       2. You may satisfy the conditions in Section 3(a)(1) in any
-          reasonable manner based on the medium, means, and context in
-          which You Share the Licensed Material. For example, it may be
-          reasonable to satisfy the conditions by providing a URI or
-          hyperlink to a resource that includes the required
-          information.
-
-       3. If requested by the Licensor, You must remove any of the
-          information required by Section 3(a)(1)(A) to the extent
-          reasonably practicable.
-
-  b. ShareAlike.
-
-     In addition to the conditions in Section 3(a), if You Share
-     Adapted Material You produce, the following conditions also apply.
-
-       1. The Adapter's License You apply must be a Creative Commons
-          license with the same License Elements, this version or
-          later, or a BY-SA Compatible License.
-
-       2. You must include the text of, or the URI or hyperlink to, the

-Section 4 -- Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that
-apply to Your use of the Licensed Material:
-
-  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
-     to extract, reuse, reproduce, and Share all or a substantial
-     portion of the contents of the database;
-
-  b. if You include all or a substantial portion of the database

-     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
-     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,

-
-Section 6 -- Term and Termination.
-
-  a. This Public License applies for the term of the Copyright and
-     Similar Rights licensed here. However, if You fail to comply with
-     this Public License, then Your rights under this Public License
-     terminate automatically.
-
-  b. Where Your right to use the Licensed Material has terminated under
-     Section 6(a), it reinstates:
-
-       1. automatically as of the date the violation is cured, provided
-          it is cured within 30 days of Your discovery of the
-          violation; or
-
-       2. upon express reinstatement by the Licensor.
-
-     For the avoidance of doubt, this Section 6(b) does not affect any
-     right the Licensor may have to seek remedies for Your violations
-     of this Public License.
-
-  c. For the avoidance of doubt, the Licensor may also offer the
-     Licensed Material under separate terms or conditions or stop
-     distributing the Licensed Material at any time; however, doing so
-     will not terminate this Public License.
-
-  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
-     License.
-
-
-Section 7 -- Other Terms and Conditions.
-
-  a. The Licensor shall not be bound by any additional or different
-     terms or conditions communicated by You unless expressly agreed.
-
-  b. Any arrangements, understandings, or agreements regarding the
-     Licensed Material not stated herein are separate from and
-     independent of the terms and conditions of this Public License.
-
-
-Section 8 -- Interpretation.
-
-  a. For the avoidance of doubt, this Public License does not, and
-     shall not be interpreted to, reduce, limit, restrict, or impose
-     conditions on any use of the Licensed Material that could lawfully
-     be made without permission under this Public License.
-
-  b. To the extent possible, if any provision of this Public License is
-     deemed unenforceable, it shall be automatically reformed to the
-     minimum extent necessary to make it enforceable. If the provision
-     cannot be reformed, it shall be severed from this Public License
-     without affecting the enforceability of the remaining terms and
-     conditions.
-
-  c. No term or condition of this Public License will be waived and no
-     failure to comply consented to unless expressly agreed to by the
-     Licensor.
-
-  d. Nothing in this Public License constitutes or may be interpreted
-     as a limitation upon, or waiver of, any privileges and immunities
-     that apply to the Licensor or You, including from the legal
-     processes of any jurisdiction or authority.

+====================

 These guides provide instructions on how to install, maintain and upgrade Odoo databases.

 .. seealso::
-    :doc:`History of Versions <administration/supported_versions>`
-
-Installation
-============
-
-Depending on the intended use case, there are multiple ways to install Odoo - or not install it at
-all.
-
- :doc:`Online <administration/odoo_online>` is the easiest way to use Odoo in production or to try it.
-
- :doc:`Packaged installers <administration/on_premise/packages>` are suitable for testing Odoo and
-  developing modules. They can be used for long-term production with additional deployment and
-  maintenance work.
-
- :doc:`Source install <administration/on_premise/source>` provides greater flexibility, as it
-  allows, for example, running multiple Odoo versions on the same system. It is adequate to develop
-  modules and can be used as a base for production deployment.
-
- A `Docker <https://hub.docker.com/_/odoo/>`_ base image is available for development or
-  deployment.
-
-.. _install/editions:
-
-Editions
-========
-
-There are two different editions.
-
-**Odoo Community** is the free and open-source version of the software, licensed under the `GNU
-LGPLv3 <https://github.com/odoo/odoo/blob/master/LICENSE>`_. It is the core upon which Odoo
-Enterprise is built.
-
-**Odoo Enterprise** is the shared source version of the software, giving access to more
-functionalities, including functional support, upgrades, and hosting. `Pricing
-<https://www.odoo.com/pricing-plan>`_ starts from one app free.
-
-.. tip::
-   :doc:`Switch from Community to Enterprise <administration/on_premise/community_to_enterprise>` at
-   any time (except for the source install).

-Transferring an on-premise database
-===================================
-
-To Odoo Online
--------------
-
-.. important::
-   - Odoo Online is *not* compatible with **non-standard apps**.
-   - The database's current version must be :doc:`supported <supported_versions>`.
-
-#. Create a :ref:`duplicate of the database <on-premise/duplicate>`.
-#. In this duplicate, uninstall all **non-standard apps**.
-#. Use the database manager to grab a *dump with filestore*.
-#. `Submit a support ticket <https://www.odoo.com/help>`_ including the following:
-
-   - your **subscription number**,
-   - the **URL** you want to use for the database (e.g., `company.odoo.com`), and
-   - the **dump** as an attachment or as a link to the file (required for 60 MB+ files).
-
-#. Odoo then makes sure the database is compatible before putting it online. In case of technical
-   issues during the process, Odoo might contact you.
-
-.. note::
-   If you have time constraints, `submit a support ticket <https://www.odoo.com/help>`_ as soon as
-   possible to schedule the transfer.
-
-To Odoo.sh
----------
-
-Follow the instructions found in :ref:`the Import your database section
-<odoo_sh_import_your_database>` of the Odoo.sh *Create your project* documentation.
-
-Transferring an Odoo Online database
-====================================
-
-.. important::
-   Odoo Online's :ref:`intermediary versions <supported_versions>` are not supported by Odoo.sh or
-   on-premise. Therefore, if the database to transfer is running an intermediary version, it must be
-   upgraded first to the next :ref:`major version <supported_versions>`, waiting for its release if
-   necessary.
-
-   .. example::
-      Transferring an online database running on Odoo 16.3 would require first upgrading it to Odoo
-      17.0.
-
-   .. tip::
-      Click the gear icon (:guilabel:`⚙`) next to the database name on the `Odoo Online database
-      manager <https://www.odoo.com/my/databases/>`_ to display its version number.
-
-   .. warning::
-      If there is an active Odoo subscription linked to the database being migrated, reach out to
-      the Customer Service Manager or `submit a support ticket <https://www.odoo.com/help>`_  to
-      complete the subscription transfer.
-
-To on-premise
-------------
-
-#. Sign in to `the Odoo Online database manager <https://www.odoo.com/my/databases/>`_ and click the
-   gear icon (:guilabel:`⚙`) next to the database name to :guilabel:`Download` a backup. If the
-   download fails due to the file being too large, `contact Odoo support
-   <https://www.odoo.com/help>`_.
-#. Restore the database from the database manager on your local server using the backup.

-================================
-
-To Odoo Online
--------------
-
-.. important::
-   Odoo Online is *not* compatible with **non-standard apps**.
-
-#. Uninstall all **non-standard apps** in a staging build before doing it in the production build.
-#. `Create a support ticket <https://www.odoo.com/help>`_ including the following:
-
-   - your **subscription number**,
-   - the **URL** you want to use for the database (e.g., `company.odoo.com`),
-   - which **branch** should be migrated,
-   - in which **region** you want the database to be hosted (Americas, Europe, or Asia),
-   - which user(s) will be the **administrator(s)**, and
-   - **when** (and in which timezone) you want the database to be up and running.
-
-#. Odoo then makes sure the database is compatible before putting it online. In case of technical
-   issues during the process, Odoo might contact you.
-
-.. note::
-   - If you have time constraints, `submit a support ticket <https://www.odoo.com/help>`_ as soon as
-     possible to schedule the transfer.
-   - Select the **region** closest to most of your users to reduce latency.
-   - Future **administrator(s)** must have an Odoo.com account.
-   - The **date and time** you want the database to be up and running are helpful to organize the
-     switch from the Odoo.sh server to the Odoo Online servers.
-   - Databases are **not reachable** during their migration.
-
-To on-premise

+System configuration
+====================
+
+This document describes basic steps to set up Odoo in production or on an
+internet-facing server. It follows :ref:`installation <setup/install>`, and is
+not generally necessary for a development systems that is not exposed on the
+internet.
+
+.. warning:: If you are setting up a public server, be sure to check our :ref:`security` recommendations!
+
+.. _db_filter:
+
+dbfilter
+========
+
+Odoo is a multi-tenant system: a single Odoo system may run and serve a number
+of database instances. It is also highly customizable, with customizations
+(starting from the modules being loaded) depending on the "current database".
+
+This is not an issue when working with the backend (web client) as a logged-in
+company user: the database can be selected when logging in, and customizations
+loaded afterwards.
+
+However it is an issue for non-logged users (portal, website) which aren't
+bound to a database: Odoo needs to know which database should be used to load
+the website page or perform the operation. If multi-tenancy is not used that is not an
+issue, there's only one database to use, but if there are multiple databases
+accessible Odoo needs a rule to know which one it should use.
+
+That is one of the purposes of :option:`--db-filter <odoo-bin --db-filter>`:
+it specifies how the database should be selected based on the hostname (domain)
+that is being requested. The value is a `regular expression`_, possibly
+including the dynamically injected hostname (``%h``) or the first subdomain
+(``%d``) through which the system is being accessed.
+
+For servers hosting multiple databases in production, especially if ``website``
+is used, dbfilter **must** be set, otherwise a number of features will not work
+correctly.
+
+Configuration samples
+---------------------
+
+* Show only databases with names beginning with 'mycompany'
+
+in :ref:`the configuration file <reference/cmdline/config_file>` set:
+
+.. code-block:: ini
+
+  [options]
+  dbfilter = ^mycompany.*$
+
+* Show only databases matching the first subdomain after ``www``: for example
+  the database "mycompany" will be shown if the incoming request
+  was sent to ``www.mycompany.com`` or ``mycompany.co.uk``, but not
+  for ``www2.mycompany.com`` or ``helpdesk.mycompany.com``.
+
+in :ref:`the configuration file <reference/cmdline/config_file>` set:
+
+.. code-block:: ini
+
+  [options]
+  dbfilter = ^%d$
+
+.. note::
+
+  Setting a proper :option:`--db-filter <odoo-bin --db-filter>` is an important part
+  of securing your deployment.
+  Once it is correctly working and only matching a single database per hostname, it
+  is strongly recommended to block access to the database manager screens,
+  and to use the ``--no-database-list`` startup parameter to prevent listing
+  your databases, and to block access to the database management screens.
+  See also security_.
+
+PostgreSQL
+==========
+
+By default, PostgreSQL only allows connection over UNIX sockets and loopback
+connections (from "localhost", the same machine the PostgreSQL server is
+installed on).
+
+UNIX socket is fine if you want Odoo and PostgreSQL to execute on the same
+machine, and is the default when no host is provided, but if you want Odoo and
+PostgreSQL to execute on different machines [#different-machines]_ it will
+need to `listen to network interfaces`_ [#remote-socket]_, either:
+
+* Only accept loopback connections and `use an SSH tunnel`_ between the
+  machine on which Odoo runs and the one on which PostgreSQL runs, then
+  configure Odoo to connect to its end of the tunnel
+* Accept connections to the machine on which Odoo is installed, possibly
+  over ssl (see `PostgreSQL connection settings`_ for details), then configure
+  Odoo to connect over the network
+
+Configuration sample

+
+Configuring Odoo
+----------------
+
+Out of the box, Odoo connects to a local postgres over UNIX socket via port
+5432. This can be overridden using :ref:`the database options
+<reference/cmdline/server/database>` when your Postgres deployment is not
+local and/or does not use the installation defaults.
+
+The :ref:`packaged installers <setup/install/packaged>` will automatically
+create a new user (``odoo``) and set it as the database user.
+
+* The database management screens are protected by the ``admin_passwd``
+  setting. This setting can only be set using configuration files, and is
+  simply checked before performing database alterations. It should be set to
+  a randomly generated value to ensure third parties can not use this
+  interface.
+* All database operations use the :ref:`database options
+  <reference/cmdline/server/database>`, including the database management
+  screen. For the database management screen to work requires that the PostgreSQL user
+  have ``createdb`` right.
+* Users can always drop databases they own. For the database management screen
+  to be completely non-functional, the PostgreSQL user needs to be created with
+  ``no-createdb`` and the database must be owned by a different PostgreSQL user.
+
+  .. warning:: the PostgreSQL user *must not* be a superuser
+
+Configuration sample
+~~~~~~~~~~~~~~~~~~~~
+
+* connect to a PostgreSQL server on 192.168.1.2

+  db_port = 5432
+  db_user = odoo
+  db_password = pwd
+  dbfilter = ^mycompany.*$
+
+.. _postgresql_ssl_connect:
+
+SSL Between Odoo and PostgreSQL
+-------------------------------
+
+Since Odoo 11.0, you can enforce ssl connection between Odoo and PostgreSQL.
+in Odoo the db_sslmode control the ssl security of the connection
+with value chosen out of 'disable', 'allow', 'prefer', 'require', 'verify-ca'
+or 'verify-full'
+
+`PostgreSQL Doc <https://www.postgresql.org/docs/12/static/libpq-ssl.html>`_
+
+.. _builtin_server:
+
+Builtin server
+==============
+
+Odoo includes built-in HTTP servers, using either multithreading or
+multiprocessing.
+
+For production use, it is recommended to use the multiprocessing server as it
+increases stability, makes somewhat better use of computing resources and can
+be better monitored and resource-restricted.
+
+* Multiprocessing is enabled by configuring :option:`a non-zero number of
+  worker processes <odoo-bin --workers>`, the number of workers should be based
+  on the number of cores in the machine (possibly with some room for cron
+  workers depending on how much cron work is predicted)
+* Worker limits can be configured based on the hardware configuration to avoid
+  resources exhaustion
+
+.. warning:: multiprocessing mode currently isn't available on Windows
+
+Worker number calculation
+-------------------------
+
+* Rule of thumb : (#CPU * 2) + 1
+* Cron workers need CPU
+* 1 worker ~= 6 concurrent users
+
+memory size calculation
+-----------------------
+
+* We consider 20% of the requests are heavy requests, while 80% are simpler ones
+* A heavy worker, when all computed field are well designed, SQL requests are well designed, ... is estimated to consume around 1GB of RAM
+* A lighter worker, in the same scenario, is estimated to consume around 150MB of RAM
+
+Needed RAM = #worker * ( (light_worker_ratio * light_worker_ram_estimation) + (heavy_worker_ratio * heavy_worker_ram_estimation) )
+
+LiveChat
+--------
+
+In multiprocessing, a dedicated LiveChat worker is automatically started and
+listening on :option:`the gevent port <odoo-bin --gevent-port>` but
+the client will not connect to it.
+
+Instead you must have a proxy redirecting requests whose URL starts with
+``/websocket/`` to the gevent port. Other request should be proxied to
+the :option:`normal HTTP port <odoo-bin --http-port>`
+
+To achieve such a thing, you'll need to deploy a reverse proxy in front of Odoo,
+like nginx or apache. When doing so, you'll need to forward some more http Headers
+to Odoo, and activate the proxy_mode in Odoo configuration to have Odoo read those
+headers.
+
+Configuration sample
+--------------------
+
+* Server with 4 CPU, 8 Thread
+* 60 concurrent users
+
+* 60 users / 6 = 10 <- theoretical number of worker needed
+* (4 * 2) + 1 = 9 <- theoretical maximal number of worker
+* We'll use 8 workers + 1 for cron. We'll also use a monitoring system to measure cpu load, and check if it's between 7 and 7.5 .
+* RAM = 9 * ((0.8*150) + (0.2*1024)) ~= 3Go RAM for Odoo
+
+in :ref:`the configuration file <reference/cmdline/config_file>`:
+
+.. code-block:: ini
+
+  [options]
+  limit_memory_hard = 1677721600
+  limit_memory_soft = 629145600
+  limit_request = 8192
+  limit_time_cpu = 600
+  limit_time_real = 1200
+  max_cron_threads = 1
+  workers = 8
+
+.. _https_proxy:
+
+HTTPS
+=====
+
+Whether it's accessed via website/web client or web service, Odoo transmits
+authentication information in cleartext. This means a secure deployment of
+Odoo must use HTTPS\ [#switching]_. SSL termination can be implemented via
+just about any SSL termination proxy, but requires the following setup:
+
+* Enable Odoo's :option:`proxy mode <odoo-bin --proxy-mode>`. This should only be enabled when Odoo is behind a reverse proxy
+* Set up the SSL termination proxy (`Nginx termination example`_)
+* Set up the proxying itself (`Nginx proxying example`_)
+* Your SSL termination proxy should also automatically redirect non-secure
+  connections to the secure port

+
+Odoo as a WSGI Application
+==========================
+
+It is also possible to mount Odoo as a standard WSGI_ application. Odoo
+provides the base for a WSGI launcher script as ``odoo-wsgi.example.py``. That
+script should be customized (possibly after copying it from the setup directory) to correctly set the
+configuration directly in :mod:`odoo.tools.config` rather than through the
+command-line or a configuration file.
+
+However the WSGI server will only expose the main HTTP endpoint for the web
+client, website and webservice API. Because Odoo does not control the creation
+of workers anymore it can not setup cron or livechat workers
+
+Cron Workers
+------------
+
+To run cron jobs for an Odoo deployment as a WSGI application requires
+
+* A classical Odoo (run via ``odoo-bin``)
+* Connected to the database in which cron jobs have to be run (via
+  :option:`odoo-bin -d`)
+* Which should not be exposed to the network. To ensure cron runners are not
+  network-accessible, it is possible to disable the built-in HTTP server
+  entirely with :option:`odoo-bin --no-http` or setting ``http_enable = False``
+  in the configuration file
+
+LiveChat
+--------
+
+The second problematic subsystem for WSGI deployments is the LiveChat: where
+most HTTP connections are relatively short and quickly free up their worker
+process for the next request, LiveChat require a long-lived connection for
+each client in order to implement near-real-time notifications.
+
+This is in conflict with the process-based worker model, as it will tie
+up worker processes and prevent new users from accessing the system. However,
+those long-lived connections do very little and mostly stay parked waiting for
+notifications.
+
+The solutions to support livechat/motifications in a WSGI application are:
+
+* Deploy a threaded version of Odoo (instead of a process-based preforking
+  one) and redirect only requests to URLs starting with ``/websocket/`` to
+  that Odoo, this is the simplest and the websocket URL can double up as the cron
+  instance.
+* Deploy an evented Odoo via ``odoo-gevent`` and proxy requests starting
+  with ``/websocket/`` to
+  :option:`the gevent port <odoo-bin --gevent-port>`.
+
+.. _deploy/streaming:
+
+Serving static files and attachments
+====================================
+
+For development convenience, Odoo directly serves all static files and attachments in its modules.
+This may not be ideal when it comes to performances, and static files should generally be served by
+a static HTTP server.
+
+Serving static files
+--------------------
+
+Odoo static files are located in each module's :file:`static/` folder, so static files can be served
+by intercepting all requests to :samp:`/{MODULE}/static/{FILE}`, and looking up the right module
+(and file) in the various addons paths.
+
+.. example::
+   Say Odoo has been installed via the **debian packages** for Community and Enterprise and the
+   :option:`--addons-path <odoo-bin --addons-path>` is ``'/usr/lib/python3/dist-packages/odoo/addons'``.
+
+   Using the above NGINX (https) configuration, the following location block should be added to
+   serve static files via NGINX.
+
+   .. code-block:: nginx
+
+       location @odoo {
+           # copy-paste the content of the / location block
+       }
+
+       # Serve static files right away
+       location ~ ^/[^/]+/static/.+$ {
+           root /usr/lib/python3/dist-packages/odoo/addons;
+           try_files $uri @odoo;
+           expires 24h;
+       }
+
+.. example::
+   Say Odoo has been installed via the **source**. The two git repositories for Community and
+   Enterprise have been cloned in :file:`/opt/odoo/community` and :file:`/opt/odoo/enterprise`
+   respectively and the :option:`--addons-path <odoo-bin --addons-path>` is
+   ``'/opt/odoo/community/odoo/addons,/opt/odoo/community/addons,/opt/odoo/enterprise'``.
+
+   Using the above NGINX (https) configuration, the following location block should be added to
+   serve static files via NGINX.
+
+   .. code-block:: nginx
+
+       location @odoo {
+           # copy-paste the content of the / location block
+       }
+
+       # Serve static files right away
+       location ~ ^/[^/]+/static/.+$ {
+           root /opt/odoo;
+           try_files /community/odoo/addons$uri /community/addons$uri /enterprise$uri @odoo;
+           expires 24h;
+       }
+
+.. warning::
+   The actual NGINX configuration you need is highly dependent on your own installation. The two
+   above snippets only highlight two possible configurations and may not be used as-is.
+
+Serving attachments
+-------------------
+
+Attachments are files stored in the filestore which access is regulated by Odoo. They cannot be
+directly accessed via a static web server as accessing them requires multiple lookups in the
+database to determine where the files are stored and whether the current user can access them or
+not.
+
+Nevertheless, once the file has been located and the access rights verified by Odoo, it is a good
+idea to serve the file using the static web server instead of Odoo. For Odoo to delegate serving
+files to the static web server, the `X-Sendfile <https://tn123.org/mod_xsendfile/>`_ (apache) or
+`X-Accel <https://www.nginx.com/resources/wiki/start/topics/examples/x-accel/>`_ (nginx) extensions
+must be enabled and configured on the static web server. Once it is set up, start Odoo with the
+:option:`--x-sendfile <odoo-bin --x-sendfile>` CLI flag (this unique flag is used for both
+X-Sendfile and X-Accel).
+
+
+.. note::
+   - The X-Sendfile extension for apache (and compatible web servers) does not require any
+     supplementary configuration.
+   - The X-Accel extension for NGINX **does** require the following additionnal configuration:
+
+     .. code-block:: nginx
+
+         location /web/filestore {
+             internal;
+             alias /path/to/odoo/data-dir/filestore;
+         }
+
+     In case you don't know what is the path to your filestore, start Odoo with the
+     :option:`--x-sendfile <odoo-bin --x-sendfile>` option and navigate to the ``/web/filestore`` URL
+     directly via Odoo (don't navigate to the URL via NGINX). This logs a warnings, the message
+     contains the configuration you need.
+
+
+.. _security:
+
+Security
+========
+
+For starters, keep in mind that securing an information system is a continuous process,
+not a one-shot operation. At any moment, you will only be as secure as the weakest link
+in your environment.
+
+So please do not take this section as the ultimate list of measures that will prevent
+all security problems. It's only intended as a summary of the first important things
+you should be sure to include in your security action plan. The rest will come
+from best security practices for your operating system and distribution,
+best practices in terms of users, passwords, and access control management, etc.
+
+When deploying an internet-facing server, please be sure to consider the following
+security-related topics:
+
+- Always set a strong super-admin admin password, and restrict access to the database
+  management pages as soon as the system is set up. See :ref:`db_manager_security`.
+
+- Choose unique logins and strong passwords for all administrator accounts on all databases.
+  Do not use 'admin' as the login. Do not use those logins for day-to-day operations,
+  only for controlling/managing the installation.
+  *Never* use any default passwords like admin/admin, even for test/staging databases.
+
+- Do **not** install demo data on internet-facing servers. Databases with demo data contain
+  default logins and passwords that can be used to get into your systems and cause significant
+  trouble, even on staging/dev systems.
+
+- Use appropriate database filters ( :option:`--db-filter <odoo-bin --db-filter>`)
+  to restrict the visibility of your databases according to the hostname.
+  See :ref:`db_filter`.
+  You may also use :option:`-d <odoo-bin -d>` to provide your own (comma-separated)
+  list of available databases to filter from, instead of letting the system fetch
+  them all from the database backend.
+
+- Once your ``db_name`` and ``db_filter`` are configured and only match a single database
+  per hostname, you should set ``list_db`` configuration option to ``False``, to prevent
+  listing databases entirely, and to block access to the database management screens
+  (this is also exposed as the :option:`--no-database-list <odoo-bin --no-database-list>`
+  command-line option)
+
+- Make sure the PostgreSQL user (:option:`--db_user <odoo-bin --db_user>`) is *not* a super-user,
+  and that your databases are owned by a different user. For example they could be owned by
+  the ``postgres`` super-user if you are using a dedicated non-privileged ``db_user``.
+  See also :ref:`setup/deploy/odoo`.
+
+- Keep installations updated by regularly installing the latest builds,
+  either via GitHub or by downloading the latest version from
+  https://www.odoo.com/page/download or http://nightly.odoo.com
+
+- Configure your server in multi-process mode with proper limits matching your typical
+  usage (memory/CPU/timeouts). See also :ref:`builtin_server`.
+
+- Run Odoo behind a web server providing HTTPS termination with a valid SSL certificate,
+  in order to prevent eavesdropping on cleartext communications. SSL certificates are
+  cheap, and many free options exist.
+  Configure the web proxy to limit the size of requests, set appropriate timeouts,
+  and then enable the :option:`proxy mode <odoo-bin --proxy-mode>` option.
+  See also :ref:`https_proxy`.
+
+- If you need to allow remote SSH access to your servers, make sure to set a strong password
+  for **all** accounts, not just `root`. It is strongly recommended to entirely disable
+  password-based authentication, and only allow public key authentication. Also consider
+  restricting access via a VPN, allowing only trusted IPs in the firewall, and/or
+  running a brute-force detection system such as `fail2ban` or equivalent.
+
+- Consider installing appropriate rate-limiting on your proxy or firewall, to prevent
+  brute-force attacks and denial of service attacks. See also :ref:`login_brute_force`
+  for specific measures.
+
+  Many network providers provide automatic mitigation for Distributed Denial of
+  Service attacks (DDOS), but this is often an optional service, so you should consult
+  with them.
+
+- Whenever possible, host your public-facing demo/test/staging instances on different
+  machines than the production ones. And apply the same security precautions as for
+  production.
+
+- If your public-facing Odoo server has access to sensitive internal network resources
+  or services (e.g. via a private VLAN), implement appropriate firewall rules to
+  protect those internal resources. This will ensure that the Odoo server cannot
+  be used accidentally (or as a result of malicious user actions) to access or disrupt
+  those internal resources.
+  Typically this can be done by applying an outbound default DENY rule on the firewall,
+  then only explicitly authorizing access to internal resources that the Odoo server
+  needs to access.
+  `Systemd IP traffic access control <http://0pointer.net/blog/ip-accounting-and-access-lists-with-systemd.html>`_
+  may also be useful to implement per-process network access control.
+
+- If your public-facing Odoo server is behind a Web Application Firewall, a load-balancer,
+  a transparent DDoS protection service (like CloudFlare) or a similar network-level
+  device, you may wish to avoid direct access to the Odoo system. It is generally
+  difficult to keep the endpoint IP addresses of your Odoo servers secret. For example
+  they can appear in web server logs when querying public systems, or in the headers
+  of emails posted from Odoo.
+  In such a situation you may want to configure your firewall so that the endpoints
+  are not accessible publicly except from the specific IP addresses of your WAF,
+  load-balancer or proxy service. Service providers like CloudFlare usually maintain
+  a public list of their IP address ranges for this purpose.
+
+- If you are hosting multiple customers, isolate customer data and files from each other

+
+
+.. _login_brute_force:
+
+Blocking Brute Force Attacks
+----------------------------
+
+For internet-facing deployments, brute force attacks on user passwords are very common, and this
+threat should not be neglected for Odoo servers. Odoo emits a log entry whenever a login attempt
+is performed, and reports the result: success or failure, along with the target login and source IP.
+
+The log entries will have the following form.
+
+Failed login::
+
+      2018-07-05 14:56:31,506 24849 INFO db_name odoo.addons.base.res.res_users: Login failed for db:db_name login:admin from 127.0.0.1
+
+Successful login::
+
+      2018-07-05 14:56:31,506 24849 INFO db_name odoo.addons.base.res.res_users: Login successful for db:db_name login:admin from 127.0.0.1
+
+
+These logs can be easily analyzed by an intrusion prevention system such as `fail2ban`.
+
+For example, the following fail2ban filter definition should match a
+failed login::
+
+    [Definition]
+    failregex = ^ \d+ INFO \S+ \S+ Login failed for db:\S+ login:\S+ from <HOST>
+    ignoreregex =
+
+This could be used with a jail definition to block the attacking IP on HTTP(S).
+
+Here is what it could look like for blocking the IP for 15 minutes when
+10 failed login attempts are detected from the same IP within 1 minute::
+
+    [odoo-login]
+    enabled = true
+    port = http,https
+    bantime = 900  ; 15 min ban
+    maxretry = 10  ; if 10 attempts
+    findtime = 60  ; within 1 min  /!\ Should be adjusted with the TZ offset
+    logpath = /var/log/odoo.log  ;  set the actual odoo log path here
+
+.. _db_manager_security:
+
+Database Manager Security
+-------------------------
+
+:ref:`setup/deploy/odoo` mentioned ``admin_passwd`` in passing.
+
+This setting is used on all database management screens (to create, delete,
+dump or restore databases).
+
+If the management screens must not be accessible at all, you should set ``list_db``
+configuration option to ``False``, to block access to all the database selection and
+management screens.
+
+.. warning::
+
+  It is strongly recommended to disable the Database Manager for any internet-facing
+  system! It is meant as a development/demo tool, to make it easy to quickly create
+  and manage databases. It is not designed for use in production, and may even expose
+  dangerous features to attackers. It is also not designed to handle large databases,
+  and may trigger memory limits.
+
+  On production systems, database management operations should always be performed by
+  the system administrator, including provisioning of new databases and automated backups.
+
+Be sure to setup an appropriate ``db_name`` parameter
+(and optionally, ``db_filter`` too) so that the system can determine the target database
+for each request, otherwise users will be blocked as they won't be allowed to choose the
+database themselves.
+
+If the management screens must only be accessible from a selected set of machines,
+use the proxy server's features to block access to all routes starting with ``/web/database``
+except (maybe) ``/web/database/selector`` which displays the database-selection screen.
+
+If the database-management screen should be left accessible, the
+``admin_passwd`` setting must be changed from its ``admin`` default: this
+password is checked before allowing database-alteration operations.
+
+It should be stored securely, and should be generated randomly e.g.
+
+.. code-block:: console
+
+    $ python3 -c 'import base64, os; print(base64.b64encode(os.urandom(24)))'
+
+which will generate a 32 characters pseudorandom printable string.
+
+Supported Browsers
+==================
+
+Odoo supports all the major desktop and mobile browsers available on the market,
+as long as they are supported by their publishers.
+
+Here are the supported browsers:
+
+- Google Chrome
+- Mozilla Firefox
+- Microsoft Edge
+- Apple Safari
+
+.. warning:: Please make sure your browser is up-to-date and still supported by
+    its publisher before filing a bug report.
+
+.. note::
+
+    Since Odoo 13.0, ES6 is supported.  Therefore, IE support is dropped.
+
+.. [#different-machines]
+    to have multiple Odoo installations use the same PostgreSQL database,
+    or to provide more computing resources to both software.
+.. [#remote-socket]
+    technically a tool like socat_ can be used to proxy UNIX sockets across
+    networks, but that is mostly for software which can only be used over
+    UNIX sockets
+.. [#switching]
+    or be accessible only over an internal packet-switched network, but that
+    requires secured switches, protections against `ARP spoofing`_ and
+    precludes usage of WiFi. Even over secure packet-switched networks,
+    deployment over HTTPS is recommended, and possible costs are lowered as
+    "self-signed" certificates are easier to deploy on a controlled
+    environment than over the internet.

+This documents attempts to describe most of the installation options.
+
+:ref:`setup/install/online`
+    The easiest way to use Odoo in production or to try it.
+
+:ref:`setup/install/packaged`

+Demo
+----
+
+To simply get a quick idea of Odoo, demo_ instances are available. They are

+around and try things out with no commitment.
+
+Demo_ instances require no local installation, just a web browser.
+
+Odoo Online
+-----------
+
+Trivial to start with, fully managed and migrated by Odoo S.A., `Odoo Online`_
+provides private instances and starts out free. It can be used to discover and
+test Odoo and do non-code customizations (i.e. incompatible with custom modules
+or the Odoo Apps Store) without having to install it locally.
+
+Can be used for both testing Odoo and long-term production use.
+
+Like demo_ instances, `Odoo Online`_ instances require no local installation, a web
+browser is sufficient.

+.. _setup/install/packaged:
+
+Packaged installers
+===================
+
+Odoo provides packaged installers for Windows, deb-based distributions
+(Debian, Ubuntu, …) and RPM-based distributions (Fedora, CentOS, RHEL, …) for
+both the Community and Enterprise versions.
+
+These packages automatically set up all dependencies (for the Community version),
+but may be difficult to keep up-to-date.
+
+Official Community packages with all relevant dependency requirements are
+available on our nightly_ server. Both Community and Enterprise packages can
+be downloaded from our download_ page (you must to be logged in as a paying
+customer or partner to download the Enterprise packages).
+
+Windows
+-------
+
+#. Download the installer from our nightly_ server (Community only) or the Windows installer from
+   the download_ page (any edition).
+#. Execute the downloaded file.

+
+      Odoo S.A. provides a repository that can be used with Debian and Ubuntu distributions. It can
+      be used to install *Odoo Community Edition* by executing the following commands:
+
+      .. code-block:: console
+
+          $ wget -q -O - https://nightly.odoo.com/odoo.key | sudo gpg --dearmor -o /usr/share/keyrings/odoo-archive-keyring.gpg

+          $ sudo apt-get update && sudo apt-get install odoo
+
+      You can then use the usual `apt-get upgrade` command to keep your installation up-to-date.
+
+   .. group-tab:: Fedora
+
+      Odoo S.A. provides a repository that can be used with the Fedora distributions. It can be used
+      to install *Odoo Community Edition* by executing the following commands:
+
+      .. code-block:: console
+
+         $ sudo dnf config-manager --add-repo=https://nightly.odoo.com/{CURRENT_MAJOR_BRANCH}/nightly/rpm/odoo.repo

+
+Distribution package
+~~~~~~~~~~~~~~~~~~~~
+
+.. tabs::
+
+   .. group-tab:: Debian/Ubuntu
+
+      Instead of using the repository as described above, the 'deb' packages for both the
+      *Community* and *Enterprise* editions can be downloaded from the `official download page
+      <download_>`_.
+
+      .. note::
+         Odoo {CURRENT_MAJOR_VERSION} 'deb' package currently supports `Debian 11 (Bullseye)`_,
+         `Ubuntu 22.04 (Jammy)`_ or above.
+
+      Next, execute the following commands **as root**:
+
+      .. code-block:: console
+
+         # dpkg -i <path_to_installation_package> # this probably fails with missing dependencies
+         # apt-get install -f # should install the missing dependencies
+         # dpkg -i <path_to_installation_package>
+
+      This will install Odoo as a service, create the necessary PostgreSQL_ user
+      and automatically start the server.
+
+      .. warning::
+         - The `python3-xlwt` Debian package does not exists in Debian Buster nor Ubuntu 18.04. This
+           python module is needed to export into xls format.

+
+           .. code-block:: console
+
+              $ sudo pip3 install xlwt
+
+         - The `num2words` python package does not exists in Debian Buster nor Ubuntu 18.04. Textual

+
+      .. note::
+         Odoo {CURRENT_MAJOR_VERSION} 'rpm' package supports Fedora 36.

+.. _setup/install/source:
+
+Source install
+==============
+
+The source "installation" is really about not installing Odoo, and running it directly from source
+instead.
+
+It can be more convenient for module developers as the Odoo source is more easily accessible than
+using packaged installation.
+
+It also makes starting and stopping Odoo more flexible and explicit than the services set up by the
+packaged installations, and allows overriding settings using
+:ref:`command-line parameters <reference/cmdline>` without needing to edit a configuration file.
+
+Finally it provides greater control over the system's set up, and allows to more easily keep
+(and run) multiple versions of Odoo side-by-side.
+
+Fetch the sources

+
+There are two ways to obtain the source code of Odoo: as a zip **archive** or through **git**.

+.. _setup/install/source/running_odoo:
+
+Running Odoo
+------------
+
+Once all dependencies are set up, Odoo can be launched by running `odoo-bin`, the
+command-line interface of the server. It is located at the root of the Odoo Community directory.
+
+To configure the server, you can either specify :ref:`command-line arguments
+<reference/cmdline/server>` or a :ref:`configuration file <reference/cmdline/config>`.
+
+.. tip::
+   For the Enterprise edition, you must add the path to the `enterprise` addons to the `addons-path`
+   argument. Note that it must come before the other paths in `addons-path` for addons to be loaded
+   correctly.
+
+Common necessary configurations are:
+
+- PostgreSQL user and password.
+- Custom addon paths beyond the defaults, to load your own modules.
+
+A typical way to run the server would be:
+
+.. tabs::
+
+   .. group-tab:: Windows
+
+      .. code-block:: doscon
+
+          C:\> cd CommunityPath/
+          C:\> python odoo-bin -r dbuser -w dbpassword --addons-path=addons -d mydb
+
+      Where `CommunityPath` is the path of the Odoo Community installation, `dbuser` is the
+      PostgreSQL login, `dbpassword` is the PostgreSQL password, and `mydb` is the name of the
+      PostgreSQL database.
+
+   .. group-tab:: Linux
+
+      .. code-block:: console
+
+          $ cd /CommunityPath
+          $ python3 odoo-bin --addons-path=addons -d mydb
+
+      Where `CommunityPath` is the path of the Odoo Community installation, and `mydb` is the name
+      of the PostgreSQL database.
+
+   .. group-tab:: Mac OS
+
+      .. code-block:: console
+
+          $ cd /CommunityPath
+          $ python3 odoo-bin --addons-path=addons -d mydb
+
+      Where `CommunityPath` is the path of the Odoo Community installation, and `mydb` is the name
+      of the PostgreSQL database.
+
+After the server has started (the INFO log `odoo.modules.loading: Modules loaded.` is printed), open
+http://localhost:8069 in your web browser and log in with the base administrator account: Use
+`admin` for the :guilabel:`Email` and, again, `admin` for the :guilabel:`Password`. That's it, you
+just logged into your own Odoo database!
+
+.. tip::
+   - From there, you can create and manage new :doc:`users
+     </applications/general/users/manage_users>`.
+   - The user account you use to log into Odoo's web interface differs from the :option:`--db_user
+     <odoo-bin -r>` CLI argument.

+Connect Microsoft Outlook 365 to Odoo using Azure OAuth
+=======================================================
+
+Odoo is compatible with Microsoft's Azure OAuth for Microsoft 365. In order to send and receive
+secure emails from a custom domain, all that is required is to configure a few settings on the
+Azure platform and on the back end of the Odoo database. This configuration works with either a
+personal email address or an address created by a custom domain.
+
+.. seealso::
+   `Microsoft Learn: Register an application with the Microsoft identity platform
+   <https://learn.microsoft.com/azure/active-directory/develop/quickstart-register-app>`_
+
+.. seealso::
+   - :doc:`/applications/general/auth/azure`
+   - :doc:`/applications/productivity/calendar/outlook`
+
+Setup in Microsoft Azure Portal
+===============================
+
+Create a new application
+------------------------
+
+To get started, go to `Microsoft's Azure Portal <https://portal.azure.com/>`_. Log in with the
+:guilabel:`Microsoft Outlook Office 365` account if there is one, otherwise log in with the
+personal :guilabel:`Microsoft account`. A user with administrative access to the Azure Settings
+will need to connect and perform the following configuration. Next, navigate to the section
+labeled :guilabel:`Manage Azure Active Directory`.
+
+Now, click on :guilabel:`Add (+)`, located in the top menu, and then select :guilabel:`App
+registration`. On the :guilabel:`Register an application` screen, rename the :guilabel:`Name` to
+`Odoo` or something recognizable. Under the :guilabel:`Supported account types` section select
+:guilabel:`Accounts in any organizational directory (Any Azure AD directory - Multitenant) and
+personal Microsoft accounts (e.g. Skype, Xbox)`.
+
+Under the :guilabel:`Redirect URL` section, select :guilabel:`Web` as the platform, and then input
+`https://<odoo base url>/microsoft_outlook/confirm` in the :guilabel:`URL` field. The Odoo base URL
+is the canonical domain at which your Odoo instance can be reached in the URL field.
+
+.. example::
+   *mydatabase.odoo.com*, where *mydatabase* is the actual prefix of the database's subdomain,
+   assuming it's hosted on Odoo.com
+
+After the URL has been added to the field, :guilabel:`Register` the application so it is created.
+
+API permissions
+---------------
+
+The :guilabel:`API permissions` should be set next. Odoo will need specific API permissions to be
+able to read (IMAP) and send (SMTP) emails in the Microsoft 365 setup. First, click the
+:guilabel:`API permissions` link, located in the left menu bar. Next, click on the :guilabel:`(+)
+Add a Permission` button and select :guilabel:`Microsoft Graph` under :guilabel:`Commonly Used
+Microsoft APIs`. After, select the :guilabel:`Delegated Permissions` option.
+
+In the search bar, search for the following :guilabel:`Deregulated permissions` and click
+:guilabel:`Add permissions` for each one:
+
+- :guilabel:`SMTP.Send`
+- :guilabel:`IMAP.AccessAsUser.All`
+
+.. note::
+   The :guilabel:`User.Read` permission will be added by default.
+
+.. image:: azure_oauth/permissions.png
+   :align: center
+   :alt: API permissions needed for Odoo integration are listed under the Microsoft Graph.
+
+Assign users and groups
+=======================
+
+After adding the API permissions, navigate back to the :guilabel:`Overview` of the
+:guilabel:`Application` in the top of the left sidebar menu.
+
+Now, add users to this application. Under the :guilabel:`Essentials` overview table, click on the
+link labeled :guilabel:`Managed Application in Local Directory`, or the last option on the bottom
+right-hand side of the table.
+
+.. image:: azure_oauth/managed-application.png
+   :align: center
+   :alt: Add users/groups by clicking the Managed application in local directory link for the
+         created application.
+
+In the left sidebar menu, select :guilabel:`Users and Groups`. Next, click on :guilabel:`(+) Add
+User/Group`. Depending on the account, either a :guilabel:`Group` and a :guilabel:`User` can be
+added, or only :guilabel:`Users`. Personal accounts will only allow for :guilabel:`Users` to be
+added.
+
+Under :guilabel:`Users` or :guilabel:`Groups`, click on :guilabel:`None Selected` and add the users
+or group of users that will be sending emails from the :guilabel:`Microsoft account` in Odoo.
+:guilabel:`Add` the users/groups, click :guilabel:`Select`, and then :guilabel:`Assign` them to the
+application.
+
+Create credentials
+------------------
+
+Now that the Microsoft Azure app is set up, credentials need to be created for the Odoo setup.
+These include the :guilabel:`Client ID` and :guilabel:`Client Secret`. To start, the
+:guilabel:`Client ID` can be copied from the :guilabel:`Overview` page of the app. The
+:guilabel:`Client ID` or :guilabel:`Application ID` is located under the :guilabel:`Display Name`
+in the :guilabel:`Essentials` overview of the app.
+
+.. image:: azure_oauth/application-id.png
+   :align: center
+   :alt: Application/Client ID located in the Overview of the app.
+
+Next, the :guilabel:`Client Secret Value` needs to be retrieved. To get this value, click on
+:guilabel:`Certificates & Secrets` in the left sidebar menu. Then, a :guilabel:`Client Secret`
+needs to be produced. In order to do this, click on the :guilabel:`(+) New Client Secret` button.
+
+A window on the right will populate with a button labeled :guilabel:`Add a client secret`. Under
+:guilabel:`Description`, type in `Odoo Fetchmail` or something recognizable, and then set the
+:guilabel:`expiration date`.
+
+.. important::
+   A new :guilabel:`Client Secret` will need to be produced and configured if the first one
+   expires. In this event, there could be an interruption of service, so the expiration date should
+   be noted and set to the furthest possible date.
+
+Next, click on :guilabel:`Add` when these two values are entered. A :guilabel:`Client Secret Value`
+and :guilabel:`Secret ID` will be created. It is important to copy the :guilabel:`Value` or
+:guilabel:`Client Secret Value` into a notepad as it will become encrypted after leaving this page.
+The :guilabel:`Secret ID` is not needed.
+
+.. image:: azure_oauth/secretvalue.png
+   :align: center
+   :alt: Client Secret Value or Value in the app's credentials.
+
+After these steps, the following items should be ready to be set up in Odoo:
+
+- A client ID (:guilabel:`Client ID` or :guilabel:`Application ID`)
+- A client secret (:guilabel:`Value` or :guilabel:`Client Secret Value`)
+
+This completes the setup on the :guilabel:`Microsoft Azure Portal` side.
+
+Setup in Odoo
+=============
+
+Enter Microsoft Outlook credentials
+-----------------------------------
+
+First, open the Odoo database and navigate to the :guilabel:`Apps` module. Then, remove the
+:guilabel:`Apps` filter from the search bar and type in `Outlook`. After that, install the module
+called :guilabel:`Microsoft Outlook`.
+
+Next, navigate to :menuselection:`Settings --> General Settings`, and under the :guilabel:`Discuss`
+section, ensure that the checkbox for :guilabel:`Custom Email Servers` is checked. This populates
+a new option for :guilabel:`Outlook Credentials`.
+
+:guilabel:`Save` the progress.
+
+Then, copy and paste the :guilabel:`Client ID` (Application ID) and :guilabel:`Client Secret
+(Client Secret Value)` into the respective fields and :guilabel:`Save` the settings.
+
+.. image:: azure_oauth/outlookcreds.png
+   :align: center
+   :alt: Outlook Credentials in Odoo General Settings.
+
+Configure outgoing email server
+-------------------------------
+
+On the :guilabel:`General Settings` page, under the :guilabel:`Custom Email Servers` setting,
+click the :guilabel:`Outgoing Email Servers` link to configure the Microsoft account.
+
+Then, create a new email server and check the box for :guilabel:`Outlook`. Next, fill in the
+:guilabel:`Name` (it can be anything) and the Microsoft Outlook email :guilabel:`Username`.
+
+If the :guilabel:`From Filter` field is empty, enter either a :ref:`domain or email address
+<email_communication/default>`.
+
+Then, click on :guilabel:`Connect your Outlook account`.
+
+A new window from Microsoft opens to complete the :guilabel:`authorization process`. Select the
+appropriate email address that is being configured in Odoo.
+
+.. image:: azure_oauth/verify-outlook.png
+   :align: center
+   :alt: Permission page to grant access between newly created app and Odoo.
+
+Then, allow Odoo to access the Microsoft account by clicking on :guilabel:`Yes`. After this, the
+page will navigate back to the newly configured :guilabel:`Outgoing Mail Server` in Odoo. The
+configuration automatically loads the :guilabel:`token` in Odoo, and a tag stating
+:guilabel:`Outlook Token Valid` appears in green.
+
+.. image:: azure_oauth/outlook-token.png
+   :align: center
+   :alt: Valid Outlook Token indicator.
+
+Finally, click :guilabel:`Test Connection`. A confirmation message should appear. The Odoo database
+can now send safe, secure emails through Microsoft Outlook using OAuth authentication.
+
+Multiple user configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Each user should have a separate server set up. The :guilabel:`from-filter` should be set so that
+only the user's email is sent from that server. In other words, only a user with an email address
+that matches the set :guilabel:`from-filter` is able to use this server.
+
+After setting the :guilabel:`from-filter`, set up a fallback email account to allow for the sending
+of :guilabel:`notifications`. The fallback email must be configured as a :guilabel:`general
+transactional server`. The :guilabel:`mail.default.from` system parameter must be set to the
+:guilabel:`username` of the general transactional server account. For more information see
+:ref:`Use a default email address <email_communication/default>`.
+
+.. note::
+   The :guilabel:`System Parameters` can be accessed by activating
+   :doc:`../../applications/general/developer_mode` in the :menuselection:`Settings --> Technical
+   --> Parameters --> System Parameters` menu.
+
+Configure incoming email server
+-------------------------------
+
+The incoming account should be configured in a similar way to the outgoing email account. Navigate
+to the :guilabel:`Incoming Mail Servers` in the :guilabel:`Technical Menu` and :guilabel:`Create` a
+new configuration. Check or Select the button next to :guilabel:`Outlook Oauth Authentication` and
+enter the :guilabel:`Microsoft Outlook username`.  Click on :guilabel:`Connect your Outlook
+account`. Odoo will state: :guilabel:`Outlook Token Valid` Now :guilabel:`Test and Confirm` the
+account. The account should be ready to receive email to the Odoo database.

+Domain names
+============
+
+A **domain name** works as an address for your website. It makes the Internet much more accessible
+as it allows users to type a meaningful web address, such as ``www.odoo.com``, rather than its
+server's IP address with a series of numbers.
+
+You can use a custom domain name to access your Odoo database and websites:
+
+- By :ref:`registering a free domain name with Odoo <domain-name/odoo-register>` (for Odoo Online
+  databases)
+- By :ref:`configuring a custom domain that you already own <domain-name/existing>`.
+
+.. note::
+   Odoo Online and Odoo.sh databases, including their websites, use by default a subdomain of
+   ``odoo.com`` for both the URL and the emails (e.g., ``https://example.odoo.com``).
+
+.. important::
+   Odoo offers a :ref:`free custom domain name <domain-name/odoo-register>` to all Odoo Online
+   databases for one year. Visitors can then access your website with an address such as
+   ``www.example.com`` rather than the default ``example.odoo.com``.

+
+About domain names
+==================
+
+Having a **good domain name** is as important to your branding as the name of your business or
+organization as it is the first thing your visitors will notice. We recommend you keep them *simple,
+short, easy to remember and spell*.
+
+A **subdomain** is a domain that is a part of another domain. It often refers to the additional part
+that comes before the main domain name. Traditionally, most websites use the ``www.`` subdomain,
+but any string of letters can be used as well. You can use subdomains to direct your visitors to
+other websites than your main website or to specific pages (e.g., ``experience.odoo.com`` points to
+a specific page.)
+
+All domain names are referenced in the **Domain Name System**, or **DNS**, which works as a giant
+directory for the Internet. There are many DNS servers, so any modification to the DNS can take up
+to 72 hours to propagate worldwide on all servers.
+
+.. _domain-name/indexing:
+
+Indexing of domain names by search engines
+------------------------------------------
+
+Search engines, such as Google and Bing, rely on web crawlers (:dfn:`robots that explore and analyze
+the web`) to index all websites and their related domain names. These crawlers discover new URLs
+thanks to links on known web pages. As a result, search engines should index domain names
+automatically after a while, as long as their URLs are mentioned elsewhere on the Internet.
+
+Improving the appearance and positioning of web pages on search engines is a practice named "Search
+Engine Optimization" (SEO).
+
+.. tip::
+   Adding relevant content, optimizing metadata, and building high-quality backlinks can all help

+way to verify the ownership of your domain name is by adding a DNS record. You can do this for
+:ref:`domain names registered with Odoo <domain-name/odoo-manage>` and for domain names managed by
+other providers.

+.. _domain-name/odoo-register:
+
+Register a free domain name with Odoo
+=====================================
+
+You can register a domain name for your Odoo Online database directly from Odoo Website or your
+database manager.
+
+.. important::
+   - Your domain name is **free for one year** if you register it with Odoo!
+   - The domain name is registered with `Gandi <https://www.gandi.net/>`_, the domain name
+     registrar.
+   - You are the owner of the domain name and can use it for other purposes.
+   - Odoo manages payment and technical support for you.
+   - This offer doesn't include any mailbox. However, you can :ref:`configure your MX records
+     <domain-name/odoo-manage>` to use your own email server or solution such as Google Workspace.
+
+To do so, go to :menuselection:`Website --> Domain Name`. Alternatively, open your `database manager
+<https://www.odoo.com/my/databases>`_, click on the :guilabel:`settings` button next to your
+database, then on :guilabel:`Domain names`.
+
+.. image:: domain_names/register-menu.png

+   :alt: The search of the domain name example.com shows which associated domains are available.
+
+Next, fill in the form with your information to become the domain name owner.
+
+Your domain name is directly linked to your database, but you still have to :ref:`map your domain
+name with your website <domain-name/website-map>`.
+
+.. note::
+   - Free domain names are also available for free Odoo Online databases (if you installed one app
+     only, for example). In this case, Odoo reviews your request and your website to avoid abuse.
+     This process may take up to three days.
+   - This is not available for Odoo.sh databases yet.

+.. _domain-name/odoo-manage:
+
+Manage your domain name registered with Odoo
+--------------------------------------------
+
+To manage the DNS records of your domain name registered with Odoo or to visualize the contacts
+associated with it, open your `database manager <https://www.odoo.com/my/databases>`_, click on the
+:guilabel:`settings` button next to your database, on :guilabel:`Domain names`, and then on
+:guilabel:`Contacts` or :guilabel:`DNS`.

+   manage your domain name.
+
+.. _domain-name/existing:
+
+Configure your existing domain name
+===================================
+
+If you already own a domain name, you can use it to point to your website.
+
+To avoid any issue with the :ref:`SSL certificate validation <domain-name/ssl>`, we highly recommend
+that you proceed with the following actions in this order:
+
+#. :ref:`Add a CNAME record <domain-name/cname>` on your domain name's DNS zone.
+#. :ref:`Map your domain name with your Odoo database <domain-name/db-map>`.
+#. :ref:`Map your domain name with your Odoo website <domain-name/website-map>`.
+
+.. _domain-name/cname:
+
+Add a CNAME record
+------------------
+
+A **CNAME record** is a type of DNS record that points to the domain of another website rather than
+directly to an IP address.
+
+You need a CNAME record that points to your Odoo database. The requirements are detailed in your
+database manager.
+
+.. tabs::
+
+   .. group-tab:: Odoo Online
+
+      The target address is the current address of your database, as defined at its creation (e.g.,
+      ``example.odoo.com``)
+
+   .. group-tab:: Odoo.sh
+
+      Your project's main address is defined in :menuselection:`Settings --> Project Name`.
+
+      If you want to target a specific branch (production, staging or development), go to
+      :menuselection:`Branches --> select your branch --> Settings --> Custom domains`, and click on
+      :guilabel:`How to set up my domain?`. A message indicates which address your CNAME record
+      should target.
+
+#. Open your domain name's manager dashboard.
+#. Open the **DNS zone** management page for the domain name you want to configure.
+#. Create a **CNAME record** pointing to the address of your database.
+
+While Odoo suggests creating a CNAME record for your ``www.`` subdomain (``www.example.com``), you
+can of course use any domain name of your choice, with any subdomain (e.g.,
+``anything.example.com``).
+
+.. example::
+   You own the domain name ``example.com``, and you have an Odoo Online database at the address
+   ``example.odoo.com``. You want to access your Odoo database primarily with the domain
+   ``www.example.com`` but also with the :ref:`naked domain <domain-name/naked-domain>`
+   ``example.com``.
+
+   To do so, you create a CNAME record for the ``www`` subdomain, with ``example.odoo.com`` as the
+   target. The DNS zone manager generates the following rule and adds it to your DNS zone: ``www IN
+   CNAME example.odoo.com.``
+
+   You also create a redirection from ``example.com`` to ``wwww.example.com``.
+
+   Your new DNS records are propagated to all DNS servers.
+
+.. note::
+   Here are some specific guidelines to create a CNAME record:
+
+   - `GoDaddy <https://www.godaddy.com/help/add-a-cname-record-19236>`_
+   - `Namecheap <https://www.namecheap.com/support/knowledgebase/article.aspx/9646/2237/how-to-create-a-cname-record-for-your-domain>`_

+
+.. _domain-name/naked-domain:
+
+Naked domain
+~~~~~~~~~~~~
+
+A **naked domain** is a domain name that doesn't have any subdomain at the beginning of the address
+(e.g., ``odoo.com`` instead of ``www.odoo.com``).
+
+You may want your naked domain to redirect to your website as some visitors may not type the full
+domain name to access your website.
+
+#. Open your domain name's manager dashboard.
+#. Create a **redirection** from the naked domain (``example.com``) to your main domain name
+   (``www.example.com``).
+
+.. note::
+   Depending on your domain name registrar, this redirection may be already pre-configured.

+      :guilabel:`settings` button next to your database, on :guilabel:`Domain names`, and then on
+      :guilabel:`Use my own domain` at the bottom of the right column.

+
+      .. seealso::
+         - :ref:`Odoo.sh branches: settings tab <odoosh-gettingstarted-branches-tabs-settings>`
+
+.. warning::
+   Make sure to :ref:`add a CNAME record <domain-name/cname>` to your domain name's DNS **before**
+   mapping your domain name with your Odoo database.
+
+   Failing to do so may impede the validation of the :ref:`SSL certificate <domain-name/ssl>` and
+   would result in a *certificate name mismatch* error. This is often displayed by web browsers as a
+   warning such as *"Your connection is not private"*.
+
+   If this is the case and you have added the domain name to your database's settings less than five
+   days ago, wait 24 hours as the validation may still happen. Otherwise, please `submit a support
+   ticket <https://www.odoo.com/help>`_ including screenshots of your CNAME records.
+
+.. _domain-name/ssl:
+
+SSL encryption (HTTPS protocol)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**SSL encryption** is an encryption-based Internet security protocol. It allows your visitors to
+navigate your website through a secure connection, which appears as an ``https://`` protocol at the
+beginning of your web address, rather than a non-secure ``http://`` protocol.
+
+Odoo generates a separate SSL certificate for each domain :ref:`mapped in the database manager
+<domain-name/db-map>`, using integration with `Let's Encrypt Certificate Authority and ACME protocol
+<https://letsencrypt.org/how-it-works/>`_.
+
+.. note::
+   - The certificate generation may take up to 24h.
+   - Several attempts to validate your certificate are made during the five days following the
+     moment you add your domain name in your database's settings.
+   - If you already use another service, you can keep using it or simply change for Odoo.
+
+.. _domain-name/web-base-url:
+
+Web base URL of a database
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. note::
+   If you have Odoo Website, you can disregard this part and directly :ref:`map your domain name
+   with your website <domain-name/website-map>`.
+
+The **web base URL** of a database, or **root URL** affects your main website address and all the
+links sent to your customers (e.g., quotations, portal links, etc.).
+
+To configure it, access your Odoo database with your custom address, then log in as an administrator
+of your database (any user in the *Settings* group) from the login screen.
+
+.. warning::
+   Connecting to your database with the original Odoo subdomain address (e.g., ``example.odoo.com``
+   also updates the web base URL of your database. See below to prevent these automatic updates.
+
+Alternatively, you can do it manually. To do so, activate the :ref:`developer mode
+<developer-mode>`, then go to :menuselection:`Settings --> Technical --> System Parameters`.
+
+Find the key called ``web.base.url`` (or create it if it does not exist) and enter the full address
+of your website as value, such as ``https://www.example.com``.
+
+.. note::
+   The URL must include the protocol ``https://`` (or ``http://``) and must not end with a slash
+   (``/``).
+
+To prevent the automatic update of the web base URL when an administrator logs in the database, you
+can create the following System Parameter:
+
+- key: ``web.base.url.freeze``
+- value: ``True``
+
+.. _domain-name/website-map:
+
+Map your domain name with your website
+======================================
+
+Mapping your domain name to your website isn't the same as mapping it with your database:
+
+- It defines your domain name as the main one for your website, helping search engines to index your
+  website properly.
+- It defines your domain name as the base URL for your database, including the portal links sent by
+  email to your customers.
+- If you have multiple websites, it maps your domain name with the appropriate website.
+
+Go to :menuselection:`Website --> Configuration --> Settings --> Website Info`. If you have multiple
+websites, select the one you want to configure.
+
+In the :guilabel:`Domain` field, fill in the web address of your website (e.g.,
+``https://www.example.com``) and click on :guilabel:`Save`.
+
+.. image:: domain_names/website-settings.png
+   :align: center
+   :alt: Configuring https://www.example.com as the Domain of the website
+
+.. warning::
+   Mapping your domain name with your Odoo website prevents Google from indexing both your custom
+   domain name ``www.example.com`` and your original odoo database address ``example.odoo.com``.
+
+   If both addresses are already indexed, it may take some time before Google removes the indexation
+   of the second address. You may also try using the `Google Search Console
+   <https://search.google.com/search-console>`_ to fix this.
+
+.. note::
+   If you have multiple websites and companies on your database, make sure that you select the
+   right :guilabel:`Company` in the website settings, next to the :guilabel:`Domain` settings. Doing
+   so indicates Odoo which URL to use as the :ref:`base URL <domain-name/web-base-url>` according to
+   the company in use.

+
+To register your database, you just need to enter your Subscription Code in the
+banner in the App Switcher. Make sure you do not add extra spaces before or after
+your subscription code. If the registration is successful, it will turn green and
+will provide you with the Expiration Date of your freshly-registered database. You
+can check this Expiration Date in the About menu (Odoo 9) or in the Settings Dashboard

+Registration Error Message
+--------------------------
+
+If you are unable to register your database, you will likely encounter this

+
+Solutions
+~~~~~~~~~
+
+* Do you have a valid Enterprise subscription?
+
+  * Check if your subscription details get the tag "In Progress" on
+    your `Odoo Account
+    <https://accounts.odoo.com/my/subscription>`__ or with your Account Manager
+
+* Have you already linked a database with your subscription reference?
+
+  * You can link only one database per subscription.
+    (Need a test or a development database? `Find a partner
+    <https://www.odoo.com/partners>`__)
+
+  * You can unlink the old database yourself on your `Odoo Contract
+    <https://accounts.odoo.com/my/subscription>`__ with the button "Unlink database"
+
+    .. image:: on_premise/unlink_single_db.png
+       :align: center
+
+    A confirmation message will appear; make sure this is the correct database as
+    it will be deactivated shortly:
+
+    .. image:: on_premise/unlink_confirm_enterprise_edition.png
+       :align: center
+
+* Do you have the updated version of Odoo 9?
+
+  * From July 2016 onward, Odoo 9 now automatically change the uuid of a
+    duplicated database; a manual operation is no longer required.
+
+  * If it's not the case, you may have multiple databases sharing the same
+    UUID. Please check on your `Odoo Contract
+    <https://accounts.odoo.com/my/subscription>`__, a short message will appear
+    specifying which database is problematic:
+
+    .. image:: on_premise/unlink_db_name_collision.png
+       :align: center
+
+    In this case, you need to change the UUID on your test databases to solve this
+    issue. You will find more information about this in :ref:`this section <duplicate_premise>`.
+
+    For your information, we identify database with UUID. Therefore, each database
+    should have a distinct UUID to ensure that registration and invoicing proceed
+    effortlessly for your and for us.
+
+* Check your network and firewall settings
+
+  * The Update notification must be able to reach Odoo's subscription
+    validation servers. In other words, make sure that the Odoo server is able
+    to open outgoing connections towards:
+
+      * services.odoo.com on port 443 (or 80)
+      * services.openerp.com on port 443 (or 80) for older deployments
+
+  * Once you activated your database, you must keep these ports open, as the
+    Update notification runs once a week.
+
+Error message due to too many users
+-----------------------------------
+
+If you have more users in your local database than provisionned in your
+Odoo Enterprise subscription, you may encounter this message:
+
+.. image:: on_premise/add_more_users.png
+   :align: center
+   :alt: This database will expire in X days, you have more users than your subscription allows
+
+
+When the message appears you have 30 days before the expiration.
+The countdown is updated everyday.
+
+Solutions
+~~~~~~~~~
+
+- **Add more users** on your subscription: follow the link and Validate
+  the upsell quotation and pay for the extra users.
+- **Deactivate users** as explained in this `documentation <documentation.html#deactivating-users>`_
+  and **Reject** the upsell quotation.
+
+Once your database has the correct number of users, the expiration message
+will disappear automatically after a few days, when the next verification occurs.
+We understand that it can be a bit frightening to see the countdown,
+so you can :ref:`force an Update Notification <force_ping>`  to make the message disappear
+right away.
+
+Database expired error message
+------------------------------
+
+If your database reaches its expiration date before your renew your subscription,
+you will encounter this message:
+
+.. image:: on_premise/database_expired.png
+   :align: center
+   :alt: This database has expired.
+
+This **blocking** message appears after a non-blocking message that lasts 30 days.
+If you fail to take action before the end of the countdown, the database is expired.
+
+Solutions
+~~~~~~~~~
+
+* Renew your subscription: follow the link and renew your subscription - note that
+    if you wish to pay by Wire Transfer, your subscription will effectively be renewed
+    only when the payment arrives, which can take a few days. Credit card payments are
+    processed immediately.

-Odoo Online
-===========
-
-`Odoo Online <https://www.odoo.com/trial>`_ provides private databases which are fully managed and
-hosted by Odoo. It can be used for long-term production or to test Odoo thoroughly, including
-customizations that don't require code.
-
-.. note::
-   Odoo Online is incompatible with custom modules or the Odoo App Store.
-
-Odoo Online databases are accessed using any web browser and do not require a local installation.
-
-To quickly try out Odoo, shared `demo <https://demo.odoo.com>`_ instances are available. No
-registration is required, but each instance only lives for a few hours.
-
-Database management
-===================
-
-To manage a database, go to the `database manager <https://www.odoo.com/my/databases>`_ and sign in
-as the database administrator.
-
-All the main database management options are available by clicking the database name, except the
-upgrade option, which can be accessed by clicking the **arrow in a circle** icon next to the
-database name. It is only displayed if an upgrade is available.

-
-How can I automate tasks when an IP address change occurs?
----------------------------------------------------------
-
-**Odoo.sh notifies project administrators of IP address changes.**
-Additionally, when the IP address of a production instance changes, an HTTP `GET` request is made
-to the path `/_odoo.sh/ip-change` with the new IP address included as a query string parameter
-(`new`), along with the previous IP address as an additional parameter (`old`).
-
-This mechanism allows custom actions to be applied in response to the IP address change
-(e.g., sending an email, contacting a firewall API, configuring database objects, etc.)
-
-For security reasons, the `/_odoo.sh/ip-change` route is accessible only internally by the platform

-  <https://accounts.odoo.com/my/subscription>`_ or contact your Account Manager.
-
- Ensure that **no other database is linked** to the subscription code, as only one database can be
-  linked per subscription.
-
-  .. tip::
-     If a test or a development database is needed, you can :ref:`duplicate a database
-     <on-premise/duplicate>`.
-
- Verify that **no databases share the same UUID** (Universally Unique Identifier) by opening your
-  `Odoo Contract <https://accounts.odoo.com/my/subscription>`_. If two or more databases share the
-  same UUID, their name will be displayed.
-

-
-  If that is the case, manually change the database(s) UUID or `send a support ticket
-  <https://www.odoo.com/help>`_.
-
- As the update notification must be able to reach Odoo's subscription validation servers, ensure
-  your **network and firewall settings** allow the Odoo server to open outgoing connections
-  towards:
-
-  - Odoo 18.0 and above: `services.odoo.com` on port `80`

-.. _dbfilter:
-
-dbfilter
-========
-
-Odoo is a multi-tenant system: a single Odoo system may run and serve a number
-of database instances. It is also highly customizable, with customizations
-(starting from the modules being loaded) depending on the "current database".
-
-This is not an issue when working with the backend (web client) as a logged-in
-company user: the database can be selected when logging in, and customizations
-loaded afterwards.
-
-However it is an issue for non-logged users (portal, website) which aren't
-bound to a database: Odoo needs to know which database should be used to load
-the website page or perform the operation. If multi-tenancy is not used that is not an
-issue, there's only one database to use, but if there are multiple databases
-accessible Odoo needs a rule to know which one it should use.
-
-That is one of the purposes of :option:`--db-filter <odoo-bin --db-filter>`:
-it specifies how the database should be selected based on the hostname (domain)
-that is being requested. The value is a `regular expression`_, possibly
-including the dynamically injected hostname (``%h``) or the first subdomain
-(``%d``) through which the system is being accessed.
-
-For servers hosting multiple databases in production, especially if ``website``
-is used, dbfilter **must** be set, otherwise a number of features will not work
-correctly.
-
-Configuration samples

-PostgreSQL
-==========
-
-By default, PostgreSQL only allows connection over UNIX sockets and loopback
-connections (from "localhost", the same machine the PostgreSQL server is
-installed on).
-
-UNIX socket is fine if you want Odoo and PostgreSQL to execute on the same
-machine, and is the default when no host is provided, but if you want Odoo and
-PostgreSQL to execute on different machines [#different-machines]_ it will
-need to `listen to network interfaces`_ [#remote-socket]_, either:
-
-* Only accept loopback connections and `use an SSH tunnel`_ between the
-  machine on which Odoo runs and the one on which PostgreSQL runs, then
-  configure Odoo to connect to its end of the tunnel
-* Accept connections to the machine on which Odoo is installed, possibly
-  over ssl (see `PostgreSQL connection settings`_ for details), then configure
-  Odoo to connect over the network
-
-Configuration sample

-Configuring Odoo
----------------
-
-Out of the box, Odoo connects to a local postgres over UNIX socket via port
-5432. This can be overridden using :ref:`the database options
-<reference/cmdline/server/database>` when your Postgres deployment is not
-local and/or does not use the installation defaults.
-
-The :doc:`packaged installers <packages>` will automatically
-create a new user (``odoo``) and set it as the database user.
-
-* The database management screens are protected by the ``admin_passwd``
-  setting. This setting can only be set using configuration files, and is
-  simply checked before performing database alterations. It should be set to
-  a randomly generated value to ensure third parties can not use this
-  interface.
-* All database operations use the :ref:`database options
-  <reference/cmdline/server/database>`, including the database management
-  screen. For the database management screen to work requires that the PostgreSQL user
-  have ``createdb`` right.
-* Users can always drop databases they own. For the database management screen
-  to be completely non-functional, the PostgreSQL user needs to be created with
-  ``no-createdb`` and the database must be owned by a different PostgreSQL user.
-
-  .. warning:: the PostgreSQL user *must not* be a superuser
-
-Configuration sample

-
-* connect to a PostgreSQL server on 192.168.1.2

-SSL Between Odoo and PostgreSQL
-------------------------------
-
-Since Odoo 11.0, you can enforce ssl connection between Odoo and PostgreSQL.

-with value chosen out of 'disable', 'allow', 'prefer', 'require', 'verify-ca'
-or 'verify-full'
-
-`PostgreSQL Doc <https://www.postgresql.org/docs/12/static/libpq-ssl.html>`_
-
-.. _builtin_server:
-
-Builtin server
-==============
-
-Odoo includes built-in HTTP, cron, and live-chat servers, using either multi-threading or
-multi-processing.
-
-The **multi-threaded** server is a simpler server primarily used for development, demonstrations,
-and its compatibility with various operating systems (including Windows). A new thread is spawned
-for every new HTTP request, even for long-lived connections such as websocket. Extra daemonic cron
-threads are spawned too. Due to a Python limitation (GIL), it doesn't make the best use of the
-hardware.
-
-The multi-threaded server is the default server, also for docker containers. It is selected by
-leaving the :option:`--workers <odoo-bin --workers>` option out or setting it to ``0``.
-
-The **multi-processing** server is a full-blown server primarily used for production. It is not
-liable to the same Python limitation (GIL) on resource usage and hence makes the best use of the
-hardware. A pool of workers is created upon server startup. New HTTP requests are queued by the OS
-until there are workers ready to process them. An extra event-driven HTTP worker for the live chat
-is spawned on an alternative port. Extra cron workers are spawned too. A configurable process
-reaper monitors resource usage and can kill/restart failed workers.
-
-The multi-processing server is opt-in. It is selected by setting the :option:`--workers
-<odoo-bin --workers>` option to a non-null integer.
-
-.. note::
-   Because it is highly customized for Linux servers, the multi-processing server is not available
-   on Windows.
-
-Worker number calculation
-------------------------
-
-* Rule of thumb : (#CPU * 2) + 1
-* Cron workers need CPU
-* 1 worker ~= 6 concurrent users
-
-memory size calculation
-----------------------
-
-* We consider 20% of the requests are heavy requests, while 80% are simpler ones
-* A heavy worker, when all computed field are well designed, SQL requests are well designed, ... is estimated to consume around 1GB of RAM
-* A lighter worker, in the same scenario, is estimated to consume around 150MB of RAM
-
-Needed RAM = #worker * ( (light_worker_ratio * light_worker_ram_estimation) + (heavy_worker_ratio * heavy_worker_ram_estimation) )
-
-LiveChat
--------
-
-In multi-processing, a dedicated LiveChat worker is automatically started and listens on
-the :option:`--gevent-port <odoo-bin --gevent-port>`. By default, the HTTP requests will keep
-accessing the normal HTTP workers instead of the LiveChat one. You must deploy a proxy in front of
-Odoo and redirect incoming requests whose path starts with ``/websocket/`` to the LiveChat worker.
-You must also start Odoo in :option:`--proxy-mode <odoo-bin --proxy-mode>` so it uses the real
-client headers (such as hostname, scheme, and IP) instead of the proxy ones.
-
-Configuration sample
--------------------
-
-* Server with 4 CPU, 8 Thread
-* 60 concurrent users
-
-* 60 users / 6 = 10 <- theoretical number of worker needed
-* (4 * 2) + 1 = 9 <- theoretical maximal number of worker
-* We'll use 8 workers + 1 for cron. We'll also use a monitoring system to measure cpu load, and check if it's between 7 and 7.5 .
-* RAM = 9 * ((0.8*150) + (0.2*1024)) ~= 3Go RAM for Odoo
-
-in :ref:`the configuration file <reference/cmdline/config_file>`:
-
-.. code-block:: ini

-  [options]
-  limit_memory_hard = 1677721600

-  limit_request = 8192
-  limit_time_cpu = 600
-  limit_time_real = 1200
-  max_cron_threads = 1
-  workers = 8
-
-.. _https_proxy:
-
-HTTPS
-=====
-
-Whether it's accessed via website/web client or web service, Odoo transmits
-authentication information in cleartext. This means a secure deployment of
-Odoo must use HTTPS\ [#switching]_. SSL termination can be implemented via
-just about any SSL termination proxy, but requires the following setup:
-
-* Enable Odoo's :option:`proxy mode <odoo-bin --proxy-mode>`. This should only be enabled when Odoo is behind a reverse proxy
-* Set up the SSL termination proxy (`Nginx termination example`_)
-* Set up the proxying itself (`Nginx proxying example`_)
-* Your SSL termination proxy should also automatically redirect non-secure
-  connections to the secure port

-HTTPS Hardening
---------------
-
-Add the `Strict-Transport-Security` header to all requests, in order to prevent
-browsers from ever sending a plain HTTP request to this domain. You will need
-to maintain a working HTTPS service with a valid certificate on this domain at
-all times, otherwise your users will see security alerts or be entirely unable
-to access it.
-
-Force HTTPS connections during a year for every visitor in NGINX with the line:
-
-.. code-block:: nginx
-
-  add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
-
-Additional configuration can be defined for the `session_id` cookie. The `Secure`
-flag can be added to ensure it is never transmitted over HTTP and `SameSite=Lax`
-to prevent authenticated `CSRF`_.

-
-  # requires nginx 1.19.8
-  proxy_cookie_flags session_id samesite=lax secure;
-
-
-Odoo as a WSGI Application
-==========================
-
-It is also possible to mount Odoo as a standard WSGI_ application. Odoo
-provides the base for a WSGI launcher script as ``odoo-wsgi.example.py``. That
-script should be customized (possibly after copying it from the setup directory) to correctly set the
-configuration directly in :mod:`odoo.tools.config` rather than through the
-command-line or a configuration file.
-
-However the WSGI server will only expose the main HTTP endpoint for the web
-client, website and webservice API. Because Odoo does not control the creation
-of workers anymore it can not setup cron or livechat workers
-
-Cron Workers
------------
-
-Starting one of the built-in Odoo servers next to the WSGI server is required to process cron jobs.
-That server must be configured to only process crons and not HTTP requests using the
-:option:`--no-http <odoo-bin --no-http>` cli option or the ``http_enable = False`` configuration
-file setting.
-
-On Linux-like systems, using the multi-processing server over the multi-threading one is recommended
-to benefit from better hardware usage and increased stability, i.e., using
-the :option:`--workers=-1 <odoo-bin --workers>` and :option:`--max-cron-threads=n
-<odoo-bin --max-cron-threads>` cli options.
-
-LiveChat
--------
-
-Using a gevent-compatible WSGI server is required for the correct operation of the live chat
-feature. That server should be able to handle many simultaneous long-lived connections but doesn't
-need a lot of processing power. All requests whose path starts with ``/websocket/`` should be
-directed to that server. A regular (thread/process-based) WSGI server should be used for all other
-requests.
-
-The Odoo cron server can also be used to serve the live chat requests. Just drop
-the :option:`--no-http <odoo-bin --no-http>` cli option from the cron server and make sure requests
-whose path starts with ``/websocket/`` are directed to this server, either on
-the :option:`--http-port <odoo-bin --http-port>` (multi-threading server) or on
-the :option:`--gevent-port <odoo-bin --gevent-port>` (multi-processing server).
-
-.. _deploy/streaming:
-
-Serving static files and attachments
-====================================
-
-For development convenience, Odoo directly serves all static files and attachments in its modules.
-This may not be ideal when it comes to performances, and static files should generally be served by
-a static HTTP server.
-
-Serving static files
--------------------
-
-Odoo static files are located in each module's :file:`static/` folder, so static files can be served
-by intercepting all requests to :samp:`/{MODULE}/static/{FILE}`, and looking up the right module
-(and file) in the various addons paths.
-
-It is recommended to set the ``Content-Security-Policy: default-src 'none'`` header on all images
-delivered by the web server. It is not strictly necessary as users cannot modify/inject content
-inside of modules' :file:`static/` folder and existing images are final (they do not fetch new
-resources by themselves). However, it is good practice.
-
-Using the above NGINX (https) configuration, the following ``map`` and ``location`` blocks should be
-added to serve static files via NGINX.
-
-.. code-block:: nginx
-
-    map $sent_http_content_type $content_type_csp {
-        default "";
-        ~image/ "default-src 'none'";
-    }
-
-    server {
-        # the rest of the configuration
-
-        location @odoo {
-            # copy-paste the content of the / location block
-        }
-
-        # Serve static files right away
-        location ~ ^/[^/]+/static/.+$ {
-            # root and try_files both depend on your addons paths
-            root ...;
-            try_files ... @odoo;
-            expires 24h;
-            add_header Content-Security-Policy $content_type_csp;
-        }
-    }
-
-The actual ``root`` and ``try_files`` directives are dependant on your installation, specifically on
-your :option:`--addons-path <odoo-bin --addons-path>`.
-
-.. example::
-
-   .. tabs::
-
-      .. group-tab:: Debian package
-
-         Say Odoo has been installed via the **debian packages** for Community and Enterprise, and
-         that the :option:`--addons-path <odoo-bin --addons-path>` is
-         ``'/usr/lib/python3/dist-packages/odoo/addons'``.
-
-         The ``root`` and ``try_files`` should be:
-
-         .. code-block:: nginx
-
-            root /usr/lib/python3/dist-packages/odoo/addons;
-            try_files $uri @odoo;
-
-      .. group-tab:: Git sources
-
-         Say Odoo has been installed via the **sources**, that both the Community and Enterprise git
-         repositories were cloned in :file:`/opt/odoo/community` and :file:`/opt/odoo/enterprise`
-         respectively, and that the :option:`--addons-path <odoo-bin --addons-path>` is
-         ``'/opt/odoo/community/odoo/addons,/opt/odoo/community/addons,/opt/odoo/enterprise'``.
-
-         The ``root`` and ``try_files`` should be:
-
-         .. code-block:: nginx
-
-            root /opt/odoo;
-            try_files /community/odoo/addons$uri /community/addons$uri /enterprise$uri @odoo;
-
-Serving attachments
-------------------
-
-Attachments are files stored in the filestore which access is regulated by Odoo. They cannot be
-directly accessed via a static web server as accessing them requires multiple lookups in the
-database to determine where the files are stored and whether the current user can access them or
-not.
-
-Nevertheless, once the file has been located and the access rights verified by Odoo, it is a good
-idea to serve the file using the static web server instead of Odoo. For Odoo to delegate serving
-files to the static web server, the `X-Sendfile <https://tn123.org/mod_xsendfile/>`_ (apache) or
-`X-Accel <https://www.nginx.com/resources/wiki/start/topics/examples/x-accel/>`_ (nginx) extensions
-must be enabled and configured on the static web server. Once it is set up, start Odoo with the
-:option:`--x-sendfile <odoo-bin --x-sendfile>` CLI flag (this unique flag is used for both
-X-Sendfile and X-Accel).
-
-
-.. note::
-   - The X-Sendfile extension for apache (and compatible web servers) does not require any
-     supplementary configuration.
-   - The X-Accel extension for NGINX **does** require the following additionnal configuration:
-
-     .. code-block:: nginx
-
-         location /web/filestore {
-             internal;
-             alias /path/to/odoo/data-dir/filestore;
-         }
-
-     In case you don't know what is the path to your filestore, start Odoo with the
-     :option:`--x-sendfile <odoo-bin --x-sendfile>` option and navigate to the ``/web/filestore`` URL
-     directly via Odoo (don't navigate to the URL via NGINX). This logs a warnings, the message
-     contains the configuration you need.
-
-
-.. _security:
-
-Security
-========
-
-For starters, keep in mind that securing an information system is a continuous process,
-not a one-shot operation. At any moment, you will only be as secure as the weakest link
-in your environment.
-
-So please do not take this section as the ultimate list of measures that will prevent
-all security problems. It's only intended as a summary of the first important things
-you should be sure to include in your security action plan. The rest will come
-from best security practices for your operating system and distribution,
-best practices in terms of users, passwords, and access control management, etc.
-
-When deploying an internet-facing server, please be sure to consider the following
-security-related topics:
-
- Always set a strong super-admin admin password, and restrict access to the database
-  management pages as soon as the system is set up. See :ref:`db_manager_security`.
-
- Choose unique logins and strong passwords for all administrator accounts on all databases.
-  Do not use 'admin' as the login. Do not use those logins for day-to-day operations,
-  only for controlling/managing the installation.
-  *Never* use any default passwords like admin/admin, even for test/staging databases.
-
- Do **not** install demo data on internet-facing servers. Databases with demo data contain
-  default logins and passwords that can be used to get into your systems and cause significant
-  trouble, even on staging/dev systems.
-
- Use appropriate database filters ( :option:`--db-filter <odoo-bin --db-filter>`)
-  to restrict the visibility of your databases according to the hostname.
-  See :ref:`dbfilter`.
-  You may also use :option:`-d <odoo-bin -d>` to provide your own (comma-separated)
-  list of available databases to filter from, instead of letting the system fetch
-  them all from the database backend.
-
- Once your ``db_name`` and ``dbfilter`` are configured and only match a single database
-  per hostname, you should set ``list_db`` configuration option to ``False``, to prevent
-  listing databases entirely, and to block access to the database management screens
-  (this is also exposed as the :option:`--no-database-list <odoo-bin --no-database-list>`
-  command-line option)
-
- Make sure the PostgreSQL user (:option:`--db_user <odoo-bin --db_user>`) is *not* a super-user,
-  and that your databases are owned by a different user. For example they could be owned by
-  the ``postgres`` super-user if you are using a dedicated non-privileged ``db_user``.
-  See also :ref:`setup/deploy/odoo`.
-
- Keep installations updated by regularly installing the latest builds,
-  either via GitHub or by downloading the latest version from
-  https://www.odoo.com/page/download or http://nightly.odoo.com
-
- Configure your server in multi-process mode with proper limits matching your typical
-  usage (memory/CPU/timeouts). See also :ref:`builtin_server`.
-
- Run Odoo behind a web server providing HTTPS termination with a valid SSL certificate,
-  in order to prevent eavesdropping on cleartext communications. SSL certificates are
-  cheap, and many free options exist.
-  Configure the web proxy to limit the size of requests, set appropriate timeouts,
-  and then enable the :option:`proxy mode <odoo-bin --proxy-mode>` option.
-  See also :ref:`https_proxy`.
-
- If you need to allow remote SSH access to your servers, make sure to set a strong password
-  for **all** accounts, not just `root`. It is strongly recommended to entirely disable
-  password-based authentication, and only allow public key authentication. Also consider
-  restricting access via a VPN, allowing only trusted IPs in the firewall, and/or
-  running a brute-force detection system such as `fail2ban` or equivalent.
-
- Consider installing appropriate rate-limiting on your proxy or firewall, to prevent
-  brute-force attacks and denial of service attacks. See also :ref:`login_brute_force`
-  for specific measures.
-
-  Many network providers provide automatic mitigation for Distributed Denial of
-  Service attacks (DDOS), but this is often an optional service, so you should consult
-  with them.
-
- Whenever possible, host your public-facing demo/test/staging instances on different
-  machines than the production ones. And apply the same security precautions as for
-  production.
-
- If your public-facing Odoo server has access to sensitive internal network resources
-  or services (e.g. via a private VLAN), implement appropriate firewall rules to
-  protect those internal resources. This will ensure that the Odoo server cannot
-  be used accidentally (or as a result of malicious user actions) to access or disrupt
-  those internal resources.
-  Typically this can be done by applying an outbound default DENY rule on the firewall,
-  then only explicitly authorizing access to internal resources that the Odoo server
-  needs to access.
-  `Systemd IP traffic access control <http://0pointer.net/blog/ip-accounting-and-access-lists-with-systemd.html>`_
-  may also be useful to implement per-process network access control.
-
- If your public-facing Odoo server is behind a Web Application Firewall, a load-balancer,
-  a transparent DDoS protection service (like CloudFlare) or a similar network-level
-  device, you may wish to avoid direct access to the Odoo system. It is generally
-  difficult to keep the endpoint IP addresses of your Odoo servers secret. For example
-  they can appear in web server logs when querying public systems, or in the headers
-  of emails posted from Odoo.
-  In such a situation you may want to configure your firewall so that the endpoints
-  are not accessible publicly except from the specific IP addresses of your WAF,
-  load-balancer or proxy service. Service providers like CloudFlare usually maintain
-  a public list of their IP address ranges for this purpose.
-
- If you are hosting multiple customers, isolate customer data and files from each other
-  using containers or appropriate "jail" techniques.
-
- Setup daily backups of your databases and filestore data, and copy them to a remote
-  archiving server that is not accessible from the server itself.
-
- Deploying Odoo on Linux is strongly recommended over Windows. Should you choose nevertheless
-  to deploy on a Windows platform, a thorough security hardening review of the server should be
-  conducted and is outside of the scope of this guide.

-.. _login_brute_force:
-
-Blocking Brute Force Attacks
----------------------------
-
-For internet-facing deployments, brute force attacks on user passwords are very common, and this
-threat should not be neglected for Odoo servers. Odoo emits a log entry whenever a login attempt
-is performed, and reports the result: success or failure, along with the target login and source IP.
-
-The log entries will have the following form.
-
-Failed login::
-
-      2018-07-05 14:56:31,506 24849 INFO db_name odoo.addons.base.res.res_users: Login failed for db:db_name login:admin from 127.0.0.1
-
-Successful login::
-
-      2018-07-05 14:56:31,506 24849 INFO db_name odoo.addons.base.res.res_users: Login successful for db:db_name login:admin from 127.0.0.1
-
-
-These logs can be easily analyzed by an intrusion prevention system such as `fail2ban`.
-
-For example, the following fail2ban filter definition should match a
-failed login::
-
-    [Definition]
-    failregex = ^ \d+ INFO \S+ \S+ Login failed for db:\S+ login:\S+ from <HOST>
-    ignoreregex =
-
-This could be used with a jail definition to block the attacking IP on HTTP(S).
-
-Here is what it could look like for blocking the IP for 15 minutes when
-10 failed login attempts are detected from the same IP within 1 minute::
-
-    [odoo-login]
-    enabled = true
-    port = http,https
-    bantime = 900  ; 15 min ban
-    maxretry = 10  ; if 10 attempts
-    findtime = 60  ; within 1 min  /!\ Should be adjusted with the TZ offset
-    logpath = /var/log/odoo.log  ;  set the actual odoo log path here
-
-.. _db_manager_security:
-
-Database Manager Security
-------------------------
-
-:ref:`setup/deploy/odoo` mentioned ``admin_passwd`` in passing.
-
-This setting is used on all database management screens (to create, delete,
-dump or restore databases).
-
-If the management screens must not be accessible at all, you should set ``list_db``
-configuration option to ``False``, to block access to all the database selection and
-management screens.
-
-.. warning::
-
-  It is strongly recommended to disable the Database Manager for any internet-facing
-  system! It is meant as a development/demo tool, to make it easy to quickly create
-  and manage databases. It is not designed for use in production, and may even expose
-  dangerous features to attackers. It is also not designed to handle large databases,
-  and may trigger memory limits.
-
-  On production systems, database management operations should always be performed by
-  the system administrator, including provisioning of new databases and automated backups.
-
-Be sure to setup an appropriate ``db_name`` parameter
-(and optionally, ``dbfilter`` too) so that the system can determine the target database
-for each request, otherwise users will be blocked as they won't be allowed to choose the
-database themselves.
-
-If the management screens must only be accessible from a selected set of machines,
-use the proxy server's features to block access to all routes starting with ``/web/database``
-except (maybe) ``/web/database/selector`` which displays the database-selection screen.
-
-If the database-management screen should be left accessible, the
-``admin_passwd`` setting must be changed from its ``admin`` default: this
-password is checked before allowing database-alteration operations.
-
-It should be stored securely, and should be generated randomly e.g.
-
-.. code-block:: console
-
-    $ python3 -c 'import base64, os; print(base64.b64encode(os.urandom(24)))'
-
-which generates a 32-character pseudorandom printable string.
-
-Reset the master password
-------------------------
-
-There may be instances where the master password is misplaced, or compromised, and needs to be
-reset. The following process is for system administrators of an Odoo on-premise database detailing
-how to manually reset and re-encrypt the master password.
-
-.. seealso::
-   For more information about changing an Odoo.com account password, see this documentation:
-   :ref:`odoocom/change_password`.
-
-When creating a new on-premise database, a random master password is generated. Odoo recommends
-using this password to secure the database. This password is implemented by default, so there is a
-secure master password for any Odoo on-premise deployment.
-
-.. warning::
-   When creating an Odoo on-premise database the installation is accessible to anyone on the
-   internet, until this password is set to secure the database.
-
-The master password is specified in the Odoo configuration file (`odoo.conf` or `odoorc` (hidden
-file)). The Odoo master password is needed to modify, create, or delete a database through the
-graphical user interface (GUI).
-
-Locate configuration file
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-First, open the Odoo configuration file (`odoo.conf` or `odoorc` (hidden file)).
-
-.. tabs::
-
-   .. tab:: Windows
-
-      The configuration file is located at: `c:\\ProgramFiles\\Odoo{VERSION}\\server\\odoo.conf`
-
-   .. tab:: Linux
-
-      Depending on how Odoo is installed on the Linux machine, the configuration file is located in
-      one of two different places:
-
-      - Package installation: `/etc/odoo.conf`
-      - Source installation: `~/.odoorc`
-
-Change old password
-~~~~~~~~~~~~~~~~~~~
-
-Once the appropriate file has been opened, proceed to modify the old password in the configuration
-file to a temporary password.
-
-.. tabs::
-
-   .. group-tab:: Graphical user interface
-
-      After locating the configuration file, open it using a (:abbr:`GUI (graphical user
-      interface)`). This can be achieved by simply double clicking on the file. Then, the device
-      should have a default :abbr:`GUI (graphical user interface)` to open the file with.
-
-      Next, modify the master password line `admin_passwd = $pbkdf2-sha…` to `admin_passwd =
-      newpassword1234`, for example. This password can be anything, as long as it is saved
-      temporarily. Make sure to modify all characters after the `=`.
-
-      .. example::
-         The line appears like this:
-         `admin_passwd =
-         $pbkdf2-sh39dji295.59mptrfW.9z6HkA$w9j9AMVmKAP17OosCqDxDv2hjsvzlLpF8Rra8I7p/b573hji540mk/.3ek0lg%kvkol6k983mkf/40fjki79m`
-
-         The modified line appears like this: `admin_passwd = newpassword1234`
-
-   .. group-tab:: Command-line interface
-
-      Modify the master password line using the following Unix command detailed below.
-
-      Connect to the Odoo server's terminal via Secure Shell (SSH) protocol, and edit the
-      configuration file. To modify the configuration file, enter the following command:
-      :command:`sudo nano /etc/odoo.conf`
-
-      After opening the configuration file, modify the master password line `admin_passwd =
-      $pbkdf2-sha…` to `admin_passwd = newpassword1234`. This password can be anything, as long as
-      it is saved temporarily. Make sure to modify all characters after the `=`.
-
-      .. example::
-         The line appears like this:
-         `admin_passwd =
-         $pbkdf2-sh39dji295.59mptrfW.9z6HkA$w9j9AMVmKAP17OosCqDxDv2hjsvzlLpF8Rra8I7p/b573hji540mk/.3ek0lg%kvkol6k983mkf/40fjki79m`
-
-         The modified line appears like this: `admin_passwd = newpassword1234`
-
-.. important::
-   It is essential that the password is changed to something else, rather than triggering a new
-   password reset by adding a semicolon `;` at the beginning of the line. This ensures the database
-   is secure throughout the entire password reset process.
-
-Restart Odoo server
-~~~~~~~~~~~~~~~~~~~
-
-After setting the temporary password, a restart of the Odoo server is **required**.
-
-.. tabs::
-
-   .. group-tab:: Graphical user interface
-
-      To restart the Odoo server, first, type `services` into the Windows :guilabel:`Search` bar.
-      Then, select the :guilabel:`Services` application, and scroll down to the :guilabel:`Odoo`
-      service.
-
-      Next, right click on :guilabel:`Odoo`, and select :guilabel:`Start` or :guilabel:`Restart`.
-      This action manually restarts the Odoo server.
-
-   .. group-tab:: Command-line interface
-
-      Restart the Odoo server by typing the command: :command:`sudo service odoo15 restart`
-
-      .. note::
-         Change the number after `odoo` to fit the specific version the server is running on.
-
-Use web interface to re-encrypt password
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-First, navigate to `/web/database/manager` or `http://server_ip:port/web/database/manager` in a
-browser.
-
-.. note::
-   Replace `server_ip` with the IP address of the database. Replace `port` with the numbered port
-   the database is accessible from.
-
-Next, click :guilabel:`Set Master Password`, and type in the previously-selected temporary password
-into the :guilabel:`Master Password` field. Following this step, type in a :guilabel:`New Master
-Password`. The :guilabel:`New Master Password` is hashed (or encrypted), once the
-:guilabel:`Continue` button is clicked.
-
-At this point, the password has been successfully reset, and a hashed version of the new password
-now appears in the configuration file.
-
-.. seealso::

-   :ref:`db_manager_security`.

-Supported Browsers
-==================
-
-Odoo supports all the major desktop and mobile browsers available on the market,
-as long as they are supported by their publishers.
-
-Here are the supported browsers:
-
- Google Chrome
- Mozilla Firefox
- Microsoft Edge
- Apple Safari
-
-.. warning:: Please make sure your browser is up-to-date and still supported by
-    its publisher before filing a bug report.
-
-.. note::
-
-    Since Odoo 13.0, ES6 is supported.  Therefore, IE support is dropped.
-
-.. [#different-machines]
-    to have multiple Odoo installations use the same PostgreSQL database,
-    or to provide more computing resources to both software.
-.. [#remote-socket]
-    technically a tool like socat_ can be used to proxy UNIX sockets across
-    networks, but that is mostly for software which can only be used over
-    UNIX sockets
-.. [#switching]
-    or be accessible only over an internal packet-switched network, but that
-    requires secured switches, protections against `ARP spoofing`_ and
-    precludes usage of WiFi. Even over secure packet-switched networks,
-    deployment over HTTPS is recommended, and possible costs are lowered as
-    "self-signed" certificates are easier to deploy on a controlled
-    environment than over the internet.

-Geo IP
-======
-
-.. note::
-   This documentation only applies to On-premise databases.
-
-Installation
-============
-
-#. Download both the GeoLite2 City and Country
-   `databases <https://dev.maxmind.com/geoip/geoip2/geolite2/>`_. You should end up with two files
-   called :file:`GeoLite2-City.mmdb` and :file:`GeoLite2-Country.mmdb`.
-
-#. Move the files to the folder :file:`/usr/share/GeoIP/`.
-
-   .. code-block:: bash
-
-       mv ~/Downloads/GeoLite2-City.mmdb /usr/share/GeoIP/
-       mv ~/Downloads/GeoLite2-Country.mmdb /usr/share/GeoIP/
-
-#. Restart the server
-
-.. note::
-   If you don't want to locate the geoip database in :file:`/usr/share/GeoIP/`, use the
-   :option:`--geoip-city-db <odoo-bin --geoip-city-db>` and
-   :option:`--geoip-country-db <odoo-bin --geoip-country-db>` options of the Odoo command line
-   interface. These options take the absolute path to the GeoIP database file and use it as the
-   GeoIP database. For example:
-
-   .. code-block:: bash
-
-      ./odoo-bin --geoip-city-db= ~/Downloads/GeoLite2-City.mmdb
-
-   .. seealso::
-      - :doc:`CLI documentation </developer/reference/cli>`.
-
-Test GeoIP geolocation in your Odoo website
-===========================================
-
-Edit a web page to include some geo-ip information such as the country name of the current
-request IP address. To do so:
-
-#. Go to your website. Open the web page that you want to test ``GeoIP``.
-#. Choose :menuselection:`Customize --> HTML/CSS/JS Editor`.
-#. Add the following piece of XML in the page :
-
-   .. code-block:: xml
-
-       <h1 class="text-center" t-esc="request.geoip.country.name or 'geoip failure'"/>
-
-#. Save and refresh the page.
-
-Geo-ip is working if you read your country name displayed in bold in the middle of the page.
-
-In case you read "**geoip failure**" instead then the geolocalization failed. The common causes are:
-
-#. The browsing IP address is the localhost (``127.0.0.1``) or a local area network one. If you
-   don't know, you can access your website using mobile data.
-#. You are using a reverse-proxy (apache, nginx) in front of Odoo but didn't start Odoo with the
-   proxy-mode enabled. See :option:`proxy mode <odoo-bin --proxy-mode>`.
-#. The GeoIP database is corrupt, missing or unaccessible. In such case a warning was logged in the
-   server logs.

-
-Using the Odoo source can be more convenient for module developers as it is more easily accessible
-than using packaged installers.
-
-It makes starting and stopping Odoo more flexible and explicit than the services set up by the
-packaged installers. Also, it allows overriding settings using :ref:`command-line parameters

-.. note::
-   **The Enterprise git repository does not contain the full Odoo source code**. It is only a

-PostgreSQL
-~~~~~~~~~~
-
-Odoo uses PostgreSQL as its database management system.
-
-.. tabs::
-
-   .. group-tab:: Linux
-
-      Use a package manager to download and install PostgreSQL (supported versions: 12.0 or above).
-      It can be achieved by executing the following:
-
-      .. code-block:: console
-
-         $ sudo apt install postgresql postgresql-client
-
-   .. group-tab:: Windows
-
-      `Download PostgreSQL <https://www.postgresql.org/download/windows>`_ (supported versions: 12.0
-      or above) and install it.
-
-   .. group-tab:: Mac OS
-
-      Use `Postgres.app <https://postgresapp.com>`_ to download and install PostgreSQL (supported
-      version: 12.0 or above).
-
-      .. tip::
-         To make the command line tools bundled with Postgres.app available, make sure to set up the
-         `$PATH` variable by following the `Postgres.app CLI tools instructions
-         <https://postgresapp.com/documentation/cli-tools.html>`_.
-
-By default, the only user is `postgres`. As Odoo forbids connecting as `postgres`, create a new
-PostgreSQL user.
-
-.. tabs::
-
-   .. group-tab:: Linux
-
-      .. code-block:: console
-
-         $ sudo -u postgres createuser -d -R -S $USER
-         $ createdb $USER
-
-      .. note::
-         Because the PostgreSQL user has the same name as the Unix login, it is possible to connect
-         to the database without a password.
-
-   .. group-tab:: Windows
-
-      #. Add PostgreSQL's `bin` directory (by default:
-         :file:`C:\\Program Files\\PostgreSQL\\<version>\\bin`) to the `PATH`.
-      #. Create a postgres user with a password using the pg admin gui:
-
-         #. Open **pgAdmin**.
-         #. Double-click the server to create a connection.
-         #. Select :menuselection:`Object --> Create --> Login/Group Role`.
-         #. Enter the username in the **Role Name** field (e.g., `odoo`).
-         #. Open the **Definition** tab, enter a password (e.g., `odoo`), and click **Save**.
-         #. Open the **Privileges** tab and switch **Can login?** to `Yes` and **Create database?**
-            to `Yes`.
-
-   .. group-tab:: Mac OS
-
-      .. code-block:: console

-Dependencies
-~~~~~~~~~~~~
-
-.. tabs::
-
-   .. group-tab:: Linux
-
-      Using **distribution packages** is the preferred way of installing dependencies.
-      Alternatively, install the Python dependencies with **pip**.
-
-      .. tabs::
-
-         .. tab:: Debian/Ubuntu
-
-            On Debian/Ubuntu, the following commands should install the required packages:
-
-            .. code-block:: console
-
-               $ cd odoo #CommunityPath
-               $ sudo ./setup/debinstall.sh
-
-            The `setup/debinstall.sh` script will parse the `debian/control
-            <{GITHUB_PATH}/debian/control>`_ file and install the found packages.
-
-         .. tab:: Install with pip
-
-            .. warning::
-               Using pip may lead to security issues and broken dependencies; only do this if you
-               know what you are doing.
-
-            As some of the Python packages need a compilation step, they require system libraries to
-            be installed.
-
-            On Debian/Ubuntu, the following command should install these required libraries:
-
-            .. code-block:: console
-
-               $ sudo apt install python3-pip libldap2-dev libpq-dev libsasl2-dev
-
-            Odoo dependencies are listed in the :file:`requirements.txt` file located at the root of
-            the Odoo Community directory.
-
-            .. note::
-               The Python packages in :file:`requirements.txt` are based on their stable/LTS
-               Debian/Ubuntu corresponding version at the moment of the Odoo release. For example,
-               for Odoo 15.0, the `python3-babel` package version is 2.8.0 in Debian Bullseye and
-               2.6.0 in Ubuntu Focal. The lowest version is then chosen in the
-               :file:`requirements.txt`.
-
-            .. tip::
-               It can be preferable not to mix Python module packages between different instances of
-               Odoo or with the system. However, it is possible to use `virtualenv
-               <https://pypi.org/project/virtualenv/>`_ to create isolated Python environments.
-
-            Navigate to the path of the Odoo Community installation (:file:`CommunityPath`) and run
-            **pip** on the requirements file to install the requirements for the current user.
-

-
-               $ cd /CommunityPath
-               $ pip install -r requirements.txt
-
-   .. group-tab:: Windows
-
-      Before installing the dependencies, download and install the `Build Tools for Visual
-      Studio <https://visualstudio.microsoft.com/downloads/>`_. Select **C++ build tools** in the

-Running Odoo
------------
-
-Once all dependencies are set up, Odoo can be launched by running `odoo-bin`, the command-line
-interface of the server. It is located at the root of the Odoo Community directory.
-
-To configure the server, either specify :ref:`command-line arguments <reference/cmdline/server>` or
-a :ref:`configuration file <reference/cmdline/config>`.
-
-.. tip::
-   For the Enterprise edition, add the path to the `enterprise` add-ons to the `addons-path`
-   argument. Note that it must come before the other paths in `addons-path` for add-ons to be loaded
-   correctly.
-
-Common necessary configurations are:
-
- PostgreSQL user and password.
- Custom addon paths beyond the defaults to load custom modules.
-
-A typical way to run the server would be:
-
-.. tabs::
-
-   .. group-tab:: Linux
-
-      .. code-block:: console
-
-         $ cd /CommunityPath
-         $ python3 odoo-bin --addons-path=addons -d mydb
-
-      Where `CommunityPath` is the path of the Odoo Community installation, and `mydb` is the name
-      of the PostgreSQL database.
-
-   .. group-tab:: Windows
-
-      .. code-block:: doscon
-
-         C:\> cd CommunityPath/
-         C:\> python odoo-bin -r dbuser -w dbpassword --addons-path=addons -d mydb
-
-      Where `CommunityPath` is the path of the Odoo Community installation, `dbuser` is the
-      PostgreSQL login, `dbpassword` is the PostgreSQL password, and `mydb` is the name of the
-      PostgreSQL database.
-
-   .. group-tab:: Mac OS
-
-      .. code-block:: console
-
-         $ cd /CommunityPath
-         $ python3 odoo-bin --addons-path=addons -d mydb
-
-      Where `CommunityPath` is the path of the Odoo Community installation, and `mydb` is the name
-      of the PostgreSQL database.
-
-After the server has started (the INFO log `odoo.modules.loading: Modules loaded.` is printed), open
-http://localhost:8069 in a web browser and log into the Odoo database with the base administrator
-account: use `admin` as the email and, again, `admin` as the password.
-
-.. tip::
-   - From there, create and manage new :doc:`users <../../applications/general/users>`.
-   - The user account used to log into Odoo's web interface differs from the :option:`--db_user
-     <odoo-bin -r>` CLI argument.

 Upgrade
 =======

-An upgrade involves moving a database from an older version to a newer supported version (e.g., from
-Odoo 16.0 to Odoo 18.0). Regular upgrades are crucial as each version offers new features, bug
-fixes, and security patches. Using a :doc:`supported version <supported_versions>` is strongly
-recommended. Each major version is supported for three years.
+.. toctree::
+   :titlesonly:

-Depending on the hosting type and Odoo version used, a database upgrade can be **mandatory**.
+   upgrade/odoo_online
+   upgrade/odoo_sh
+   upgrade/on_premise
+   upgrade/faq

-.. tabs::
-
-   .. group-tab:: Odoo Online
-
-      - If a database is on a **major version** (e.g., 16.0, 17.0, 18.0), an upgrade is mandatory
-        every two years.
-      - If a database is on a **minor version** (e.g., 17.1, 17.2, 17.4), an upgrade is mandatory
-        a few weeks after the next version is released. Minor versions are usually released every
-        two months.
-
-   .. group-tab:: Odoo.sh
-
-      After the initial three years of support, you will have another two years to complete the
-      upgrade. You will be notified when an upgrade is required.
-
-      .. image:: upgrade/odoo-sh-message.png
-         :alt: The "unsupported version" popup on Odoo.sh.
-
-   .. group-tab:: On-premise
-
-      You can stay on the same version indefinitely, even if it is not recommended. Note that the
-      smaller the version gap, the easier the upgrade should be.
-
-.. spoiler:: Automatic upgrades: Odoo Online's Rolling Release process
-
-   You will receive a notification in your database a few weeks before a mandatory upgrade will be
-   automatically carried out. You are in control of the process as long as the deadline is not
-   reached.
-
-   .. image:: upgrade/rr-upgrade-message.png
-      :alt: The upgrade message prompt on the top right of the database
-
-   Concretely, Odoo’s Upgrade Team performs a silent test upgrade of every database that should be
-   upgraded. If the test is successful and lasts less than 20 minutes, you can directly trigger the
-   upgrade from the database. If the test fails, you can test an upgrade using the `database manager
-   <https://www.odoo.com/my/databases>`_.
-
-   When you are invited to upgrade, it is strongly recommended to :ref:`request an upgraded test
-   database <upgrade-request-test>` first and spend time :ref:`testing <upgrade-testing>` it.
-
-   An automatic upgrade to the next version will be triggered if no action is taken before the
-   specified due date.
+An upgrade is switching to a newer version of Odoo (e.g., Odoo 14.0 to Odoo 15.0).

 An upgrade does not cover:

-  - Downgrading to a previous version of Odoo
-  - :doc:`Switching editions <on_premise/community_to_enterprise>` (e.g., from Community to
-    Enterprise)
-  - :ref:`Changing hosting type <hosting/change-solution>` (e.g., from on-premise to Odoo Online)
-  - Migrating from another ERP to Odoo
+* Changing :ref:`editions <upgrade-faq/editions-change>` (i.e., Community to Enterprise edition)
+* Switching :ref:`hosting type <upgrade-faq/hosting-types-switch>` (i.e., On-Premise to Odoo Online
+  or Odoo.sh)
+* Migration from another ERP to Odoo

-.. warning::
-   If your database contains custom modules, it cannot be upgraded until a version of your custom
-   modules is available for the target version of Odoo. For customers maintaining their own custom
-   modules, we recommend to parallelize the process by :ref:`requesting an upgraded database
-   <upgrade-request-test>` while also :doc:`upgrading the source code of your custom
-   modules </developer/howtos/upgrade_custom_db>`.

-Upgrading in a nutshell
+.. _upgrade/process-workflow:
+
+Process workflow
+================
+
+The upgrade process in a nutshell:
+
+#. You create a test upgrade request.
+#. Odoo processes the request automatically by running the database through an upgrade script, which
+   takes between 20 and 120 minutes.
+#. Odoo delivers a test database.
+#. You test your database for possible discrepancies (see :ref:`upgrade/test-guidance`).
+#. If there are any discrepancies, you report them to the Upgrade support team via the help portal
+   (see :ref:`upgrade/test-assistance`).
+#. We fix the issues and send you a new test database.
+#. Once you have completed the testing and are happy with the result, you decide on a date and time
+   when you stop users from accessing Odoo, freeze all data entries, and create an upgrade request
+   for the production upgrade.
+#. Odoo delivers the production database through the automated process.
+#. You restore it in your Production environment a few short hours later and continue working on the
+   newly upgraded database (this is done automatically on Odoo Online).

+.. _upgrade/testing-phase:
+
+Testing
+=======
+
+This phase allows you to review an upgraded version of your database without affecting your
+production database in any way. We suggest that you run the test upgrade process at least once, but
+you can do it as many times as you need (one at a time).
+
+Once you receive your upgraded test database, check that all data, processes, and functionality are
+still correct and working as expected.
+
+If you do find discrepancies, :ref:`report your issues <upgrade/test-assistance>` and :ref:`request
+a new test database <upgrade/test-db-request>` when the reported issues are fixed in the upgrade
+script.
+
+If you do not find any discrepancies, you can move on to the upgrade of your production database.
+
+.. important::
+   A test database is only intended for testing and remains completely unrelated to your present or
+   future production database. Any data you add, or changes you make, will not be reflected in your
+   upgraded production database.
+
+.. note::
+   Test databases are neutered and features are disabled to prevent them from having an impact on
+   the production database:
+
+   #. The serial number of the database is modified (to prevent it from sending information as if it
+      was the production database).
+   #. The :ref:`base URL of the database <domain-name/web-base-url>` is reset to
+      ``http://localhost:8069`` and the email domain to ``localhost``.
+   #. Scheduled actions are disabled (the calendar synchronization, the bank statement
+      synchronization, the planned automated actions, the fetching of incoming mail servers, etc.).
+   #. Outgoing mail servers are disabled by archiving the existing ones and adding a
+      fake/non-working one.
+   #. Payment providers and delivery carriers are reset to test environment.
+   #. Accounting localization Electronic Data Interchange (EDI) services are disabled.
+   #. A system parameter is set to tell the database has been neutered.

+
+Request a test database
 =======================

-#. Request an upgraded test database (see :ref:`obtaining an upgraded test database
-   <upgrade-request-test>`).
-#. If applicable, upgrade the source code of your custom module to be compatible with the new
-   version of Odoo (see :doc:`/developer/howtos/upgrade_custom_db`).
-#. Thoroughly test the upgraded database (see :ref:`testing the new version of the database
-   <upgrade-testing>`).
-#. Report any issue encountered during the testing to Odoo by going to the `Support page and
-   selecting "An issue related to my future upgrade (I am testing an upgrade)"
-   <https://www.odoo.com/help?stage=migration>`_.
-#. Once all issues are resolved and you are confident that the upgraded database can be used as
-   your main database without any issues, plan the upgrade of your production database.
-#. Request the upgrade for the production database, rendering it unavailable for the time it takes
-   to complete the process (see :ref:`upgrading the production database <upgrade-production>`).
-#. Report any issue encountered during the upgrade to Odoo by going to the `Support page and
-   selecting "An issue related to my upgrade (production)"

-Obtaining an upgraded test database
-===================================
+.. _upgrade/test-guidance:

-The `Upgrade page <https://upgrade.odoo.com>`_ is the main platform for requesting an upgraded
-database. However, depending on the hosting type, you can upgrade from the command line
-(on-premise), the Odoo Online `database manager <https://www.odoo.com/my/databases>`_, or your
-`Odoo.sh project <https://www.odoo.sh/project>`_.
+Test guidance
+=============
+
+Every business and organization has its own operational needs and has to test its specific Odoo
+database individually. We recommend you look at `the test scenario
+<https://docs.google.com/document/d/1ypNs7JKPOsjNbKpdiKFH7Al6g6whZ9jr7f7duAQ5E1w/>`_ for further

-
-      Odoo Online databases can be manually upgraded via the `database manager
-      <https://www.odoo.com/my/databases>`_.
-
-      The database manager displays all databases associated with the user's account. Databases
-      not on the most recent version of Odoo display an arrow in a circle icon next to their name,
-      indicating that they can be upgraded.
-
-      .. image:: upgrade/databases-page.png
-         :alt: The database manager with an upgrade button next to the name of a database.
-
-      Click the **arrow in a circle** icon to start the upgrade process. In the popup, fill in:
-
-      - The **version** of Odoo you want to upgrade to, usually the latest version
-      - The **email** address that should receive the link to the upgraded database
-      - The :guilabel:`Purpose` of the upgrade, which is automatically set to :guilabel:`Test` for
-        your first upgrade request
-
-      .. image:: upgrade/upgrade-popup.png
-         :alt: The "Upgrade your database" popup.
-
-      The :guilabel:`Upgrade in progress` tag is displayed next to the database name until
-      completion. Once the process succeeds, an email containing a link to the upgraded test
-      database is sent to the address provided. The database can also be accessed from the database
-      manager by clicking the dropdown arrow before the database name.
-
-      .. image:: upgrade/access-upgraded-db.png
-         :alt: Clicking the menu arrow displays the upgraded test database.

-
-      .. image:: upgrade/odoo-sh-staging.png
-         :alt: Odoo.sh project and tabs
-
-      The **latest production daily automatic backup** is then sent to the Upgrade platform.
-
-      Once the upgrade platform is done upgrading the backup and uploading it on the branch, it is
-      put in a **special mode**: each time a **commit is pushed** on the branch, a **restore
-      operation** of the upgraded backup and an **update of all the custom modules** occur. This
-      allows you to test your custom modules on a pristine copy of the upgraded database. The log
-      file of the upgrade process can be found in your newly upgraded staging build by going to
-      :file:`~/logs/upgrade.log`.
-
-      .. important::
-         In databases where custom modules are installed, their source code must be up-to-date with
-         the target version of Odoo before the upgrade can be performed. If there are none, the
-         "update on commit" mode is skipped, the upgraded database is built as soon as it is
-         transferred from the upgrade platform, and the upgrade mode is exited.
-
-         Check out the :doc:`/developer/howtos/upgrade_custom_db` page for more information.
-
-   .. group-tab:: On-premise
-
-      The standard upgrade process can be initiated by entering the following command line on the
-      machine where the database is hosted:
-
-      .. code-block:: console
-
-         $ python <(curl -s https://upgrade.odoo.com/upgrade) test -d <your db name> -t <target version>
-
-      .. note::
-         This command has some requirements on the environment it runs in:
-
-         - Some external commands that must be provided by the operating system, normally found in
-           any Linux distribution (including WSL). An error will be displayed if one or several of
-           them are missing.
-         - The system user that executes the command needs to be configured with access to the
-           database. Please refer to the PostgreSQL documentation of the `client environment
-           <https://www.postgresql.org/docs/current/libpq-envars.html>`_ or the `client password
-           file <https://www.postgresql.org/docs/current/libpq-pgpass.html>`_ for this requirement.
-         - The script needs to be able to reach one or multiple servers of the upgrade platform
-           both on TCP port 443 and to any random TCP port in the range between 32768 and 60999.
-           This can be in conflict with your restrictive firewall and may need an exception added
-           to the firewall configuration.
-
-      The following command can be used to display the general help and the main commands:
-
-      .. code-block:: console
-
-         $ python <(curl -s https://upgrade.odoo.com/upgrade) --help
-
-      An upgraded test database can also be requested via the `Upgrade page
-      <https://upgrade.odoo.com>`_.
-
-      .. important::
-         In databases where custom modules are installed, their source code must be up-to-date with
-         the target version of Odoo before the upgrade can be performed. Check out the
-         :doc:`/developer/howtos/upgrade_custom_db` page for more information.
-
-      .. note::
-         - For security reasons, only the person who submitted the upgrade request can download it.
-         - For storage reasons, the database's copy is submitted without a filestore to the upgrade
-           server. Therefore, the upgraded database does not contain the production filestore.
-         - Before restoring the upgraded database, its filestore must be merged with the production
-           filestore to be able to perform tests in the same conditions as it would be in the new
-           version.
-         - The upgraded database contains:
-
-           - A `dump.sql` file containing the upgraded database
-           - A `filestore` folder containing files extracted from in-database records into
-             attachments (if there are any) and new standard Odoo files from the targeted Odoo
-             version (e.g., new images, icons, payment provider's logos, etc.).
-             This is the folder that should be merged with the production filestore
-             in order to get the full upgraded filestore.
-
-.. note::
-   You can request multiple test databases if you wish to test an upgrade more than once.
-
-.. note::
-   When an upgrade request is completed, an upgrade report is attached to the successful upgrade
-   email, and it becomes available in the Discuss app for users who are part of the "Administration
-   / Settings" group. This report provides important information about the changes introduced by
-   the new version.
-
-.. _upgrade-testing:
-
-Testing the new version of the database
-=======================================
-
-It is essential to test the upgraded test database to ensure that you are not stuck in your
-day-to-day activities by a change in views, behavior, or an error message once the upgrade goes
-live.
-
-.. note::
-   Test databases are neutralized, and some features are disabled to prevent them from impacting the
-   production database:
-
-   #. Scheduled actions are disabled.
-   #. Outgoing mail servers are disabled by archiving the existing ones and adding a fake one.
-   #. Payment providers and delivery carriers are reset to the test environment.
-   #. Bank synchronization is disabled. Should you want to test the synchronization, contact your
-      bank synchronization provider to get sandbox credentials.
-
-Testing as many of your business flows as possible is strongly recommended to ensure they are
-working correctly and to get more familiar with the new version.
-
-.. admonition:: Basic test checklist
-
-   - Are there views that are deactivated in your test database but active in your production
-     database?
-   - Are your usual views still displayed correctly?
-   - Are your reports (invoice, sales order, etc.) correctly generated?
-   - Are your website pages working correctly?
-   - Are you able to create and modify records? (sales orders, invoices, purchases, users, contacts,
-     companies, etc.)
-   - Are there any issues with your mail templates?
-   - Are there any issues with saved translations?
-   - Are your search filters still present?
-   - Can you export your data?
-
-.. spoiler:: Example of end-to-end testing
-
-   - Checking a random product in your product catalog and comparing its test and production data to
-     verify everything is the same (product category, selling price, cost price, vendor, accounts,
-     routes, etc.).
-   - Buying this product (Purchase app).
-   - Confirming the reception of this product (Inventory app).
-   - Checking if the route to receive this product is the same in your production database
-     (Inventory app).
-   - Selling this product (Sales app) to a random customer.
-   - Opening your customer database (Contacts app), selecting a customer (or company), and checking
-     its data.
-   - Shipping this product (Inventory app).
-   - Checking if the route to ship this product is the same as in your production database
-     (Inventory app).
-   - Validating a customer invoice (Invoicing or Accounting app).
-   - Crediting the invoice (issuing a credit note) and checking if it behaves as in your production
+   * The purpose of the test phase is not to correct existing data or configurations in your
     database.
-   - Checking your reports' results (Accounting app).
-   - Randomly checking your taxes, currencies, bank accounts, and fiscal year (Accounting app).
-   - Making an online order (Website apps) from the product selection in your shop until the
-     checkout process and checking if everything behaves as in your production database.
+   * |assistance-contact|

-   This list is **not** exhaustive. Extend the example to your other apps based on your use of Odoo.
+.. _upgrade/steps-production:

-If you face an issue while testing your upgraded test database, you can request the assistance of
-Odoo by going to the `Support page and selecting "An issue related to my future upgrade (I am
-testing an upgrade)" <https://www.odoo.com/help?stage=migration>`_. In any case, it is essential to
-report any problem encountered during the testing to fix it before upgrading your production
-database.
+The production launch
+=====================

-You might encounter significant differences with standard views, features, fields, and models during
-testing. Those changes cannot be reverted on a case-by-case basis. However, if a change introduced
-by a new version breaks a customization, it is the responsibility of the maintainer of your custom
-module to make it compatible with the new version of Odoo.
+The production upgrade request is when you decide to upgrade your current database with all your
+production data (invoices, VAT returns, inventories, current orders) to a new version of your
+choice.

-.. tip::
-   Do not forget to test:
-
-   - Integrations with external software (EDI, APIs, etc.)
-   - Workflows between different apps (online sales with eCommerce, converting a lead all the way to
-     a sales order, delivery of products, etc.)
-   - Data exports
-   - Automated actions
-   - Server actions in the action menu on form views, as well as by selecting multiple records on
-     list views
-
-.. _upgrade-production:
-
-Upgrading the production database
-=================================
-
-Once the :ref:`tests <upgrade-testing>` are completed and you are confident that the upgraded
-database can be used as your main database without any issues, it is time to plan the go-live day.
-
-Your production database will be unavailable during its upgrade. Therefore, we recommend planning
-the upgrade at a time when the use of the database is minimal.
-
-As the standard upgrade scripts and your database are constantly evolving, it is also recommended
-to frequently request another upgraded test database to ensure that the upgrade process is still
-successful, especially if it takes a long time to finish. **Fully rehearsing the upgrade process the
-day before upgrading the production database is also recommended.**
+After your :ref:`tests <upgrade/testing-phase>` are completed to your satisfaction, submit the
+request to upgrade your production database via our `website form <https://upgrade.odoo.com>`_.
+Select *Production* purpose.

 .. important::
   Going into production without first testing may lead to:

-   - Users failing to adjust to the changes and new features
-   - Business interruptions (e.g., no longer having the possibility to validate an action)
-   - Poor customer experience (e.g., an eCommerce website that does not work correctly)
+   - business interruptions (e.g., no longer having the possibility to validate an action)

+Why upgrade
+===========
+
+* You benefit from the latest features of the :ref:`new major version
+  <upgrade-faq/release-notes>` released by Odoo.
+* If you are in an :ref:`unsupported version <upgrade/supported-versions>`, you get a new version
+  with support.
+
+.. _upgrade-faq/when:
+
+When to upgrade
+===============
+
+Whenever you want. You can make your upgrade request as soon as a new version is released or when
+your version turns unsupported, and you still wish to enjoy support.
+
+.. _upgrade-faq/availability:
+
+Availability of the new version
+===============================
+
+As soon as Odoo announces the release of a new major version, you can create a test upgrade request
+to try the latest version. Please note that at this point, the upgrade scripts will only have been
+tested with demo data. Please report any issue you might encounter while testing via the `Odoo
+Support page <https://www.odoo.com/help>`_ and make sure to be happy with your test version before
+requesting the upgrade of your database in production.
+
+.. _upgrade-faq/duration:
+
+Duration of the upgrade
+=======================
+
+It is impossible to give time estimates for every upgrade request.
+
+In general, the "smaller" the database, the quickest the upgrade request is completed. A single-user
+database that uses only CRM will be processed faster than a multi-company, multi-user database that
+uses Accounting, Sales, Purchase, and Manufacturing.
+
+You can expect the time it takes for the platform to upgrade the test database to be similar to the
+production upgrade.
+
+.. _upgrade-faq/project:
+
+Duration of the upgrade project
+-------------------------------
+
+It depends on the user involvement (the time spent on testing, reporting problems, etc.) and the
+issues encountered that might need to be addressed by our technical team.
+
+So, in a nutshell, what can impact your upgrade lead time?
+
+* Source & targeted versions
+* Installed apps
+* Volume of data
+* Amount of customization (models, fields, methods, workflows, reports, website, etc.)
+* Installation of new apps or configuration changes after the start of the test phase
+* User commitment

+.. _upgrade-faq/editions-change:
+
+Editions change (from Community to Enterprise)
+==============================================
+
+The upgrade always returns an Enterprise edition of Odoo, whether the database you sent was a
+community or enterprise edition. It is required to have an enterprise subscription to upgrade.
+
+ .. note::
+    If you need assistance on this matter,  please contact us via the `Odoo Support page

+
+.. _upgrade-faq/upgrade-report:
+
+The Upgrade Report
+==================
+
+When an upgrade request completes successfully (test or production), you receive an email
+notification about it that includes an 'Upgrade Report'. This report is also sent to you via the
+Discuss app. It contains valuable information regarding changes that occurred during the upgrade.
+While it serves as a guide to possible issues to look out for, it is not an exhaustive list. It
+remains imperative that you test the upgraded database thoroughly and report any discrepancies you
+might find, before you decide to upgrade your production database.
+
+.. _upgrade-faq/custom-views:
+
+Custom views
+============
+
+During the upgrade, some custom views might get disabled for technical reasons. Therefore they might
+have to be fixed after the upgrade. The :ref:`Upgrade Report <upgrade-faq/upgrade-report>` that is
+generated after the upgrade is available in the Discuss app, and lists all the custom views that
+might be impacted by this.
+
+.. _upgrade-faq/release-notes:
+
+Release Notes by version
+========================
+
+Open our `Release Note <https://www.odoo.com/page/release-notes>`_ page to get a summary of the new
+features and improvements made in each version.
+
+How long is my test available for
+=================================
+
+An Odoo Online test database is available for one month by default. We can extend this trial period
+upon request. For Odoo.sh or on-premise, there is no restriction.
+
+How many tests to perform before upgrading to production?
+=========================================================
+
+As many as needed. When you are comfortable with the database, run a last test upgrade 48 hours
+before requesting your production upgrade and test your workflows one last time.
+
+How to/Where to report upgrade issues?
+======================================
+
+If you encounter issues during the upgrade process, please contact the Odoo Support through the
+`Odoo Support page <https://www.odoo.com/help>`_.
+
+- To report an issue discovered during the testing phase, please select **An issue related to my
+  upgrade (test phase)**.
+- To report an issue discovered post-upgrade, please select **An issue related to my upgrade
+  (production)**.
+
+Upgrading to production
+=======================
+
+Once you have completed testing and are happy with the result, you decide on a date and time when
+you stop users from accessing Odoo, freeze all data entries, and create an upgrade request for the
+production upgrade.
+
+How is my data handled in the Upgrade Platform?
+===============================================
+
+The Odoo Upgrade platform uses the same Privacy Policy as the rest of Odoo.com services.
+
+Your data is hosted on servers that follow our security guidelines, namely:
+
+- SSL - All web connections to client instances are protected with 256-bit SSL encryption
+  (HTTPS with a 2048-bit modulus SSL certificate), and running behind Grade A SSL stacks. All our
+  certificate chains are using SHA-2 already.
+- Safe System - Our servers are running recent Linux distribution with up-to-date security patches,
+  with firewall and intrusion countermeasures (not disclosed for obvious reasons).
+
+Servers are located at the same locations as our Cloud providers with the following services:
+
+- Restricted perimeter, physically accessed by authorized data center employees only
+- Physical access control with security badges or biometrical security
+- Security cameras monitoring the data center locations 24/7
+- Security personnel on-site 24/7
+
+The uploaded and migrated databases uploaded to the Upgrade platform are kept for up to 3 months and
+are permanently deleted following that period.
+
+You can learn more about privacy and data handling at Odoo by visiting our `General Data Protection
+Regulation page <https://www.odoo.com/gdpr>`_.
+
+Rolling Release (applicable to Odoo Online databases)
+=====================================================
+
+This feature allows customers to upgrade their database directly from a message prompt sent to the
+database administrator as soon as the new version is released. Odoo first tests the upgrade to the
+next version. The rolling release upgrade option is displayed if the automated tests are successful.
+The message offers two options:
+
+#. To 'Upgrade Now', which immediately triggers the upgrade of your live production database.
+
+#. To take you to your `database manager <https://www.odoo.com/my/databases/>`_ where you can
+   `request an upgraded test database <https://upgrade.odoo.com/#online/>`_ and check the upgraded
+   test database for any discrepancies.
+
+When you choose to proceed with the production upgrade directly, make sure all users have saved
+their work and are logged out. The upgrade takes approximately 15 minutes. During this time your
+database is unreachable. If you notice any problem after the upgrade, please report it via the `Odoo
+Support page <https://www.odoo.com/help>`_.
+
+.. note::
+   If you are using the Website or Studio app, we recommend you always do a test upgrade before
+   upgrading your production instance.

+Odoo Online
+===========
+
+Odoo databases can be manually upgraded directly from the main Odoo website. To upgrade an Odoo
+database, navigate to the `database manager <https://www.odoo.com/my/databases>`_ page and sign in.
+
+The database manager page displays all of the Odoo databases associated with the user's account. Any
+databases that are not already on the most recent version of Odoo display an **arrow in a circle**
+icon next to the database name, indicating that the database can be upgraded.
+
+.. image:: odoo_online/databases-page.png
+   :align: center
+   :alt: The database manager page with an upgrade button next to the name of a database.
+
+.. important::
+   - If the database's version is **lower** than the latest major release: the database must be
+     upgraded within two months. After these two months, an automatic upgrade is initiated.
+   - If the database's version is **equal** to or **higher** than the latest major release:
+     you can disregard the invitation to upgrade, as the database probably would not benefit from
+     new features every two months.
+
+If a database is *not* on the latest online version, its administrator should receive an invitation
+to upgrade on the database's dashboard, displayed as an **arrow in a circle**.
+
+.. image:: odoo_online/database-notification.png
+   :alt: Invitation to upgrade on the database dashboard.
+
+.. note::
+   Versions that are not supported anymore become deprecated and must be updated to avoid
+   security issues. It is recommended to initiate the upgrade yourself and not wait for the
+   automatic upgrade, as the former method allows you to request a test upgrade of the database to
+   check for any discrepancies.
+
+Test database
+=============
+
+Click on the **arrow in a circle** icon to start the upgrade process. On the :guilabel:`Upgrade your
+database` pop-up, select the version of Odoo that the platform will be upgraded to. In the
+:guilabel:`Email to notify` field, enter an email address that will receive email notifications
+about the database upgrade.
+
+There is also a :guilabel:`Purpose` section on the pop-up that is used to specify the reason for the
+upgrade. However, at this stage of the process, the only selectable option is :guilabel:`Test`, as
+Odoo requires users to create a test copy of the upgraded database before converting the actual
+database.
+
+.. image:: odoo_online/upgrade-pop-up.png
+   :align: center
+   :alt: The "Upgrade your database" pop-up.
+
+After filling out the form, click the :guilabel:`Upgrade` button. The pop-up disappears and the
+database being upgraded shows a red :guilabel:`Upgrade in progress` tag next to its name. An email
+confirming that the upgrade is in progress is also sent to the email address specified on the
+pop-up.
+
+.. image:: odoo_online/upgrade-in-progress.png
+   :align: center
+   :alt: The "Upgrade in progress" tag next to the database name.
+
+Once the upgrade is complete, a new test database appears on the `database manager
+<https://www.odoo.com/my/databases>`_ page. To access the test database, click the drop-down arrow
+(:guilabel:`⯆`) to the left of the main database's name. Doing so makes the test version appear
+below it. Finally, click the green :guilabel:`Connect` button on the right side of the test
+version's row to go to the database.
+
+.. image:: odoo_online/test-database.png
+   :align: center
+   :alt: A test database on the database manager page.
+
+Except for being on the newer version of Odoo, the test database is an exact copy of the one being
+upgraded. It is important to do extensive testing in this database to ensure that the upgrade has
+not altered or corrupted any data, and that all workflows still proceed as expected.
+
+Production database
+===================
+
+After confirming the integrity of the new version, return to the `database manager
+<https://www.odoo.com/my/databases>`_ page. Once again, click on the **arrow in a circle** icon next
+to the database being upgraded. The :guilabel:`Upgrade your database` pop-up appears as before,
+except that there is now a :guilabel:`Production` option under the :guilabel:`Purpose` section.
+
+Select the :guilabel:`Production` option and then click :guilabel:`Upgrade` to begin the upgrade
+process. As before, a notification email is sent to the email address provided and a red
+:guilabel:`Upgrade in progress` tag appears next to the name of the database.
+
+The production database is then taken offline and will be upgraded automatically. The time it takes
+to upgrade the production database should be similar to the time that was necessary to upgrade the
+test database. Make sure to inform database users of the scheduled downtime.
+
+After the upgrade is finished, the :guilabel:`Upgrade in progress` tag disappears and the database
+is upgraded to the version specified.
