Automated migration script

Introduction

note that the original maintainer of this script deprecated this in favor of a dedicated buildout as described in https://github.com/OCA/OpenUpgrade/issues/502, at the moment, this script won’t be able to migrate to versions above 9.0

For users who just want to run a migration, there is the convenience script migrate.py that takes care of downloading the necessary branches, set up a configuration for the migration and passing the correct parameters to the OpenUpgrade server.

Download it from github.

The script assumes that all python libraries that are required by Odoo are installed in the current environment.

The script accepts a couple of parameters, the mandatory ones are

--config=[your original config file]
this file will be used to craft a new config file for the migration process
--database=[the database to migrate]
this database will be migrated. The script takes care of making a copy of it before running the migration, your migrated database will be called ${name}_migrated.
--run-migrations=[list of migrations to run]
the migrations to run. Note: You always name the target migration, so if you want to migrate a 6.1 database to 7.0, you pass --run-migrations=7.0. For multiple migrations, i.e. migrate a 6.0 database to 7.0, separate the versions with a comma: --run-migrations=6.1,7.0

(use --help for some other handy ones)

Have a cup of tea now, it will take a while. When it’s done, the first thing you should do is to examine /var/tmp/openupgrade/migration.log. Carefully read through eventual warnings, there will be a lot, most of them not fatal. If nothing weird showed up there, enjoy using your new database with the target version of Odoo.

Problems

Please report problems to https://github.com/OCA/openupgrade/issues (very often, it’s not a bug but a specific issue with your database setup). Make sure to have read your migration.log file carefully to avoid posting about obvious issues. Post relevant lines from the logfile, but don’t post the whole logfile. If you can’t decide what would be relevant, upload the file somewhere and link to that in your question.

In a nutshell

wget https://raw.githubusercontent.com/OCA/OpenUpgrade/HEAD/scripts/migrate.py
