2008 R2 Hyper-V Host Upgrade to 2012 R2

I have a 2008 R2 Hyper-V host running two VMs. One is a 2008 R2 guest and the other is a 2012 R2 guest. I'm getting some networking errors in the system logs on the 2012 R2 guest. It would appear I should be running my host on 2012 R2.

My question is what is the best way to get there? Do I do an in place upgrade of my host from 2008 R2 to 2012 R2? Or do I do a clean reload of the host OS to 2012 R2? If the latter, how do I handle my virtual servers? Do I need to export them first, then import them into the new host?

I look forward to your replies.

I would recommend a clean installation of Windows 2012 R2.

and then look at my EE Article

Is the OS installed on a separate partition from the configuration and VHD files?

If yes, flatten, install fresh, drivers, configure networking and storage, and finally use the Import wizard in Hyper-V 2012 to get the VMs in.

Integration Services would need to be upgraded on the 08 R2 guest.

Thanks Andrew. Your article seems to cover migrating from one server to another. This would be more of a swing to the same hardware. Does that change the process much?

Phil, yes the OS in on a separate partition from the VMs. Wouldn't I need to first Export to be able to import the VMs into 2012?

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

Just Export the VMs to a USB External Disk, or Network Share, and then RE-Import from there.

No, one does not need to run the export/import process. The Hyper-V Import wizard will ask for a folder with the VM(s) in it and run the process.

Import has been significantly improved in 2012 RTM/R2.

As always, have a good backup of the guests before making significant changes!

Thanks guys. After discussing your feedback with the client, we will spin-up a new 2008R2 VM and migrate the one application that is running on the 2012 R2 VM. This is the least disruptive method for the client.

I split points for those that replied.
