Hyper-V 2012 Replica and Live Migration

Posted on 2013-01-28

I have two Server 2012 severs with about 10 VMs. Hyper-V replica is enabled for all of them replicating every 5 min or so. If I want to move the machine without shutting it down can I use Live Migration instead? With Hyper-V replica I need to shut down the machine first which I can't do during business hours. If the machine is moved over to the other host that is also being replicated with Replica will things get confused here? Will Replica know the server is now running on host 2?

I need so clarification

Thank you

Do you have a SAN and have you enabled Clustering?

no SAN, nor clustering. Just local storage on both identical hosts

if you have no SAN or Clustering you can use what's been called

Shared Nothing Live Migration


Live Migrate running VM's to/from: Hyper-V Host <-> Hyper-V Host

Hyper-V Replica against VM mobility scenarios including Live Migration of Hyper-V Replica-enabled VMs is compatible. So you can Live Migrate VMs which have been HYper-V Replica enabled.

I tried in my test environment and when I tried t LM a VM that is already replicated with Hyper-V replica it told me that the machine already exisit on the other host so the only way I was able to LM the VM was to disable HVR for that machine. Am I missing something?
