=======
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.
Depending on the hosting type and Odoo version used, a database upgrade can be **mandatory**.
.. 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 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
.. 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>`.
.. _upgrade-nutshell:
Upgrading in a nutshell
=======================
#. 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)"
<https://www.odoo.com/help?stage=post_upgrade>`_.
.. _upgrade-request-test:
Obtaining an upgraded test database
===================================
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>`_.
.. note::
The Upgrade platform follows the same `Privacy Policy <https://www.odoo.com/privacy>`_ as the
other Odoo.com services. Visit the `General Data Protection Regulation page
<https://www.odoo.com/gdpr>`_ to learn more about how Odoo handles your data and privacy.
.. tabs::
.. group-tab:: Odoo Online
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.
.. group-tab:: Odoo.sh
Odoo.sh is integrated with the upgrade platform to simplify the upgrade process.
.. 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
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.
This list is **not** exhaustive. Extend the example to your other apps based on your use of Odoo.
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.
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.
.. 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.**
.. 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)
The process of upgrading a production database is similar to upgrading a test database, but with a
few exceptions.
.. tabs::
.. group-tab:: Odoo Online
The process is similar to :ref:`obtaining an upgraded test database
<upgrade-request-test>`, except for the purpose option, which must be set to
:guilabel:`Production` instead of :guilabel:`Test`.
.. warning::
Once the upgrade is requested, the database will be unavailable until the upgrade is
finished. Once the process is completed, it is impossible to revert to the previous
version.
.. group-tab:: Odoo.sh
The process is similar to :ref:`obtaining an upgraded test database <upgrade-request-test>` on
the :guilabel:`Production` branch.
.. image:: upgrade/odoo-sh-prod.png
:alt: View from the upgrade tab
The process is **triggered as soon as a new commit is made** on the branch. This
allows the upgrade process to be synchronized with the deployment of the custom modules'
upgraded source code.
If there are no custom modules, the upgrade process is triggered immediately.
.. important::
The database is unavailable throughout the process. If anything goes wrong, the platform
automatically reverts the upgrade, as it would be for a regular update. In case of success,
a backup of the database before the upgrade is created.
The update of your custom modules must be successful to complete the entire upgrade process.
Make sure the status of your staging upgrade is :guilabel:`successful` before trying it in
production. More information on how to upgrade your custom modules can be found on
:doc:`/developer/howtos/upgrade_custom_db`.
.. group-tab:: On-premise
The command to upgrade a database to production is similar to the one of upgrading a test
database except for the argument `test`, which must be replaced by `production`:
.. code-block:: console
$ python <(curl -s https://upgrade.odoo.com/upgrade) production -d <your db name> -t <target version>
An upgraded production database can also be requested via the `Upgrade page
<https://upgrade.odoo.com>`_.
Once the database is uploaded, any modification to your production database will **not** be
present on your upgraded database. This is why we recommend not using it during the upgrade
process.
.. important::
When requesting an upgraded database for production purposes, the copy is submitted without
a filestore. Therefore, the upgraded database filestore must be merged with the production
filestore before deploying the new version.
In case of an issue with your production database, you can request the assistance of Odoo by going
to the `Support page and selecting "An issue related to my upgrade (production)"
<https://www.odoo.com/help?stage=post_upgrade>`_.
.. _upgrade-sla:
