One of the websites I’m hosting wants to move to a new host that uses CPanel. If I do a full backup of his virtual server sans the Virtualmin server settings, could he then import that into his CPanel and be good to go?
I’ve gone from CPanel to Virtualmin, but not the other way around.
If you use Virtualmin’s standard backup module and create an archive of your client’s virtual server, it will contain everything that is required to restore the domain(s) on another system, regardless of which web hosting panel is in use on the other system.
Would it be a one-click restore on the other system? Yes, if the other system has the ability to import Virtualmin backups; absent which the systems admin of the other system will have to manually restore from the archive; not difficult for any adept person to accomplish.
