I have a working VDI setup that I'm trying to migrate from Server 2008 R2 to Server 2012, but I can't get the broker to see the VMs on the 2012 virtualization host server. Ideally, I'd like to continue using the existing 2008 R2 broker. I have created a new 2012 broker (and redirector), in case the problem was with mixing 2008 and 2012, but it also shows 0 VMs. I've even created a new VPC from scratch on the 2012 server, which also doesn't show up.
I'm at a loss of how to diagnose the problem. Is it even possible to keep the same configuration (2008 broker and redirector) and just move the VMs to the 2012 Hyper-V, or should I give up on that idea?
The broker and redirector are separate 2008 R2 virtual PCs, now running off the 2012 Hyper-V. When I originally added the 2012 server to the 2008 broker, as a new virtualization host server, I got a message saying that the Hyper-V Virtual Machine Manager wasn't running. Now (after creating the 2012 broker) I get a message (when adding the 2012 server to the 2008 broker) saying that it's already assigned to the 2012 broker, and I'd have to remove it for the machines to show up.
I'm hoping someone can point me in the right direction to diagnose where the problem is, and perhaps confirm if I do have to (or should) focus on creating a 2012-only broker/redirector, or if I can somehow get the 2012 Hyper-V to show up as a virtualization host in the existing configuration.
