Migrating Email From CPanel
I'm attempting to migrate some accounts from CPanel to a brand new ISPConfig 3 installation. The web sites and databases should just be a matter of creating backups and copying them to their new locations. But it looks like the formats used to store old email are completely different between the two. How could I migrate these accounts' email over without loosing the saved messages that have already been delivered? Is there some documentation on the two formats used?
