I'm developing and using cayenne-migrations. It works fine for me and has a very similar approach to ERXMigrations. I don't think others are using it though. It has the advantage of being able to auto-generate the migration code from your cayenne model (DataMap), where I think the others require hand coding. On the other hand, sometimes having all pure SQL statements instead of mostly java code is useful. Good luck!
