Axelor Postgresql database migrate

I need to migrate the PostgreSQL database from an older Axelor 5.3 to Axelor 6.1. The databases are on the same server just there are some differences on the databases, the new version has some additional tables or fields. There is not much data to transfer may be just 10% of the tables has been used for about 8 months. Identifying tables differences may not be much difficult as well.

Unfortunately Axelor would provide support to enterprise customers only.
