cPanel migration


I’m looking for a replacement of WHM/cPanel.

I see Virtualmin has one import tool for restoring a cPanel backup.

I looked for the data it imports but I don’t found nothing.

It imports, mail accounts, mails, domains, dns, files of the websites, etc…

On my cPanel I have lots of domains, and it seems virtualmin only can import backups of only one domain. This it’s correct?
