 Hi adev, I did a little looking around and it looks like you're right that their backup script forces you to download a full backup to your local machine. I did find a post that was a few years old now that talked about logging into your cPanel and then going to https://cpanel_url:0000/frontend/x0/backup/fullbackup.html and supposedly that worked. I have no idea if it's still possible to use or not. To get back to your question about whether or not you can copy emails over the answer is yes you can. I've done it. You'll just need to make sure that the files are chowned properly, have the correct permissions, and are in the correct places too of course. This is also assuming that you're using the Dovecot on both servers as well.
