I have 2 Ubuntu servers both running Virtualmin. Server 1 is just a web server and server 2 is mail and DNS. I would like to migrate the 2 of them. I figure it would be easier to move the web server into the mail server ( the mail server has a more recent version of Ubuntu). If I backup the mail server and restore it into the mail server will it add the web part to the rest of the services it wipe out the other.
