I recently had to convert a Server 2008 R2 Virtual Primary Domain Controller to a Physical Server.
I scratched my head for a while and wondered how best to do it. I was thinking of using storagecraft, then thinking of installing a new server , running dcpromo and then transferring AD Roles.
But I used Windows 2008 Server Backup and backed up my Virtual Primary Domain Controller to a Bufallo Linkstation Pro. The Virtual DC was installed on a dynamic disk. I then restored it via bootup repair options from a Server 2008R2 USB Drive.
It took 15 mins!
