The migration between tryton versions is fully suported. In order to migrate an existing database to a newer version you must take the following actions:
- Obtain the new version of trytond and all the instaled modules. You can update your existing installation or create a new one.
- Update the database with trytond -u all -d <database>, where <database> refers to your database name.
Migrating custom modules
If you have developed custom modules it's possible that you have to adapt your code in order to get it working with the new tryton version.
