I am hoping someone can steer me in the right direction. I have done some research, but can not seem to find the exact answer to my particular question.
I have 3 host 2008 R2 hyper v environment, which is connected to an HP MSA ISCSI SAN. It’s configured for clustering and is using CSV. This is the current production environment.
I built a new 3 host 2012 hyper v environment, which is connected to a new Nimble ISCSI SAN. It’s configured for clustering and is using CSV. This will be the new production environment.
I have been testing the best (read fasted with least downtime) way to get the VMs from the 2008 to 2012.. I have done an export, then an import (however you have to have the machine offline for the export), I did a straight copy, from one SAN to the other, then imported (again took some time, and needed to be off-line (at least for the last few mins), I even did a P to V in 2012.. This seemed to work OK, but I am not sure if I am asking for issues down the road.
So my question is, is the a better way to do this?
Thank you for any assistance.
