I have a multi server setup. I am upgrading my email server from Ubuntu 14.04 to Debian 8 (tried out the auto installation which worked great. ) I know how to move all the emails. However what I don't know is how to copy the email domain and email users to the new server in ISPconfig. Any easy ways or do I create a new email domain on the new server? And do I have to recreate all users on the new server? Thanks! EDIT: So I did some trial and error. If you go into the database and changes all of your Server_ID fields to the new server, then go into ISPConfig and the Resync option, it will transfer the information to the new server. Then you just need to rsync the information over to the new server and you are good to go.
