They just need to be same brand. I have cluster with 5100, 5300, 5500, and 5600 series processors. Hyper-V won't let you live migrate them if there is going to be a compatibility problem.

Never a problem as long as enable processor migration is enabled on the VM.

Well, it specifically means that the processor instructions that are available on the newer chips but not the older chips won't be available. I don't know if that actually affects my performance. My performance is good enough, and if it's ever slow, it is because of disk IO issues, not CPU, so I say that for me needs performance is good enough.
