I’m currently trying to move my Database A to Database B but when i restore Database A to Database B and login to Kinetic B. I checked that my Company Configuration is gone like empty and ask for create new record but when i press yes it comes with error too. My question is there a proper way to migrate Database A to Database B?
You should never move your dev database over to live.
Did you have both installed and working in separate application servers? You shut down the pilot/test app server in the Epicor Admin Console then restore your live database to pilot/test and rename the db. Then restart the pilot/test app server and task servers.
