I have 2 mailcow servers running. Today I’ve started to migrate both to one new system. I’ve successfully made it with my first mailcow using backup_and_restore to backup on the old server and restore on the new one.
Now I have the problem if i backup on the 2nd old server and want to restore on the new one, it asks me for overwriting the mailcow.conf again because of the database user and password. Both old server had it’s own automatic generated db user and password in the config. So, if i press n it says the restore was successfull but i still only see the users and mailboxes from my first old server but not additionally the ones from my second old server. I think it’s because the mailcow.conf only accesses the database user from the first one.
What can i do to “merge” both of my backups into my one new server?
