Openupgrade Framework

Beta License: AGPL-3 OCA/OpenUpgrade Translate me on Weblate

This module is a technical module that contains a number of monkeypatches to improve the behaviour of Odoo when migrating your database using the OpenUpgrade migration scripts:

  • Prevent dropping columns or tables in the database when fields or models are obsoleted in the Odoo data model of the target release. After the migration, you can review and delete unused database tables and columns using database_cleanup. See https://odoo-community.org/shop/product/database-cleanup-918
  • When data records are deleted during the migration (such as views or other system records), this is done in a secure mode. If the deletion fails because of some unforeseen dependency, the deletion will be cancelled and a message is logged, after which the migration continues.
  • Prevent a number of log messages that do not apply when using OpenUpgrade.
  • Suppress log messages about failed view validation, which are to be expected during a migration.
  • Run migration scripts for modules that are installed as new dependencies of upgraded modules (when there are such scripts for those particular modules)
  • Production databases generated with demo data, will be transformed to non-demo ones. If you want to avoid that, you have to pass through the environment variable OPENUPGRADE_USE_DEMO, the value “yes”.

Table of contents


This module does not need to be installed on a database. It simply needs to be available via your addons-path.


  • call your odoo instance with the option --load=base,web,openupgrade_framework


  • add the key to your configuration file:
server_wide_modules = web,openupgrade_framework

When you load the module in either way of these ways, and you have the openupgrade_scripts module in your addons path available, the –upgrade-path option of Odoo will be set automatically to the location of the OpenUpgrade migration scripts.


The odoo_patch folder contains python files in a tree that mimicks the folder tree of the Odoo project. It contains a number of monkey patches to improve the migration of an Odoo database between two major versions.

So far, we are able to make everything work without overwriting large blocks of code, but if larger patches need to be added, please use the method described below:

To see the patches added, you can use meld tools:


To make more easy the diff analysis :

  • Make sure the python files has the same path as the original one.
  • Keep the same indentation as the original file. (using if True: if required)
  • Add the following two lines at the beginning of your file, to avoid flake8 / pylint errors
# flake8: noqa
# pylint: skip-file
  • When you want to change the code. add the following tags:

For an addition:

# <OpenUpgrade:ADD>
some code...
# </OpenUpgrade>

For a change:

# <OpenUpgrade:CHANGE>
some code...
# </OpenUpgrade>

For a removal:

# <OpenUpgrade:REMOVE>
# Comment the code, instead of removing it.
# </OpenUpgrade>
