Server 2012 Hyper-V from Server 08 R2
Posted on 2013-06-18
Currently I have 2 Server 2008 R2 ENT Hyper-V servers. I have about 8 VMs running on each of them. I also have an EMC VNXe 3100. Each Hyper-V server has a LUN connected to it and that is where the VHD files live. My question is can I "detach" the LUN from Hyper-V server "A", format that server and install Server 2012. Install Hyper-V, and then re-attach the LUN, and spin the VMs back up? I guess my question is are the VMs themselves migratable? Do I need to "export and import", or can I just reattach, reconfigure the RAM, PROCs, NICs, etc, and spin up?
