I will start this question by saying I am pretty sure what I am asking is not "Best Practice" and I am not sure it is even supported but I wanted to find out if it is possible.
Scenario:
Server 1 running WS2012 Hyper-V and hosting VM1. Replica of VM1 is sent to Server 2 also running WS2012 Hyper-V. These servers are shared nothing but are connected via 1 Gbps LAN. Can you live migrate from server 1 to server 2 and avoid disk migration time by using the existing replica as a seed?
You might ask why in the world would you do this? I know all the details of replicas are for DR (in theory WAN based DR) and live migration is for local. That being said I have a single production server that runs everything but I have an older server with slower proc and disk but enough ram to work short term and is better than downtime. I am using replicas to this older server as a poor mans local HA and then have offsite backup for DR. I don't have shared disk nor the funding right now to acquire it to do a cluster and I am not sure I want to cluster it anyway. If I want to take down the primary server for service / patching it would be great to quickly live migrate to replica server for a short term then allow reverse replication and then initiate live migration back.
Thanks for any thoughts or info. Also if this doesn't work in WS2012 any changes coming in WS2012R2?
