In place upgrade Hyper-V Server 2012 R2 to Windows Server 2012 R2 with Hyper-V

Hi Experts.

I have a Hyper-V Server 2012 R2 host which I'd like to upgrade to Windows Server 2012 R2 with Hyper-V

Is it possible to do an in place upgrade or is a fresh install required?

Thanks for you help and advice.

Fresh install. At least your VM would still be there, but you should probably export it so you can easily import it again. :-( Why are you looking to switch?

Do you have 2012 plain and wanted to upgrade to 2012 R2 or what?
This is doable.


Do you want to install 2012 R2 hyper-v edition (Free)?
In that case fresh install is the only option
IMHO, even if a direct update/upgrade is possible, the risk that "Murphy's Law" rears its implication when most unwanted and  unexpected should encourage any to handle transitions in a methodical way that allows for a way back should anything go wrong. reinstalling on the same system Is the same thing.  If you have the option to install on a new platform, you should consider doing that.

It sounds as though the Hyper-V VMs are fine, but you have another task that would benefit from running on the host?

Sorry for the delay in responding but I've been away for long weekend.

kevinhsieh & Arnold  - I want to use the GUI and take advantage of additional features which I understand are not available with Hyper-V Server 2012 R2 e.g. Windows Server Backup.

Mahesh - I have Hyper-V Server 2012 R2 (free edition) installed and but now want to use Windows Server 2012 R2 with Hyper-V instead.
Hyper-v (free) has an option to install windows backup. And has a mechanism.  Setting up a fully functional server with hyper-v role solely seemingly for convenience of invoking the various tools means you would be sacrificing the additional resources that would have been available to the VMs.

Arnold - yes I'd rather keep the host resource requirements to a minimum and stay with Hyper-V Server 2012 R2 if possible.

Could you give me a steer on how to install/access Windows Server Backup please?

Ocsetup WindowsServerBackup
wbadmin -start backup ......

Look at oclist (to list available rules/sea turns)
Ocsetup toad/install them
Wbadmin to manage the various.........
