As I don’t like and use the DB-first approach [1], I use cayenne-migrations for this. It works a lot like ERXMigration in WOnder.

Staging and dev databases are replaced by fresh copies of the production database every week. So code and model are first, and also the model may differ between branches as we develop several features in parallel. I have no idea how anyone who has more than just a single production database could use a db first approach. > Am 14.08.2018 um 09:36 schrieb Andrus Adamchik <and...@objectstyle.org>: > > The modeler migrate schema functionality is not sophisticated enough for > production workflows.
