2008 R2 Hyper-V Host Upgrade to 2012 R2
Posted on 2014-12-10
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.
