And, for question 1, migrating from cPanel using a backup from your cPanel system is built-in.
CWP is not supported, and I’ve never seen it or looked at its backups, so I have no suggestions for how you might migrate from it. Virtualmin definitely has no built-in support for migrating from CWP. Nobody’s ever asked for it, as far as I know, so it’s never been on our radar (and since migration is a pretty complicated subject and takes a ton of development time, it’d have to be a very popular control panel to get that kind of attention).
We have support for migrating from cPanel, Plesk (several versions, as the format of their backups has changed several times), DirectAdmin, and a couple of others…but the couple others probably don’t count as they haven’t been touched in years, and are no longer popular or maintained (I mean the control panel isn’t popular or maintained, not just that our migration support isn’t being updated).
exactly. virtualmin, I created this confusion because in the datacenter that I am a client, it presents webmin as an alternative to cpanel and plesk. for this reason I thought it really was. but thank you very much for clarifying. now i learned. hehe
