Microsoft HyperV -- restore steps ?

I currently have OLD server
with BackupExec restores/etc and
want to upgrade to Windows 2012

Are below steps #3 and #4
really as easy as they seem ?

Any good "Microsoft HyperV"
articles explaining the RESTORE
process in more detail?
 1. 2012 domain controller is on HyperV physical server #1
 2. physical server #1 hareware/software breaks and
    2012 domain controller is no longer working correctly
 3. I "STOP" 2012 domain controller VM on physical server #1
 4. I "START" last night's HyperV physical server #1
    backup VM that is already on physical server #2
 5. 2012 domain controller works again via physical server #2
 6. I order parts/etc to fix physical server #1

Probably not that easy. Last I checked, backup exec did not do AD-aware restores so following that process could create USN issues. If you have a second server available, it'd be better to run a replica domain controller instead of restoring a backup from a non-AD backup utility. Alternatively, you'd want to use a backup program that is AD aware.

I am not I understand the question: is it a theoretical question “in case if it breaks” or you are actually planning to move an old DC to a virtual machine?

If it’s a pure theoretical I would recommend having two domain controllers running on both host servers. In that case if the first one breaks, you can stop it and replace the defective parts without losing connectivity to a DC. By aware, that restoring a DC is not like restoring any other server.

If you are planning a migration/move to 2012 DC, I would recommend installing and promoting a new DC from scratch and demoting the old one.
