Good Day Everyone,
Ok so my dilemma is that I HAVE to upgrade one of our 2012 Datacenter Servers w/Hyper-V hosting to 2012 R2. The part that troubles me is that I have 3 Production VM's on this server, do I have to migrate these off the Host Controller before I conduct the upgrade? Can I shut them down and just conduct the upgrade? What is the risk? I have backups of all the VM's, however I do not have another server currently setup to handle the Live Migration as they are full, but I could make something work if I had to move them before the upgrade.
