Hi, we have two physical servers. Both running Win2008 (non-R2). Server1 has a Hyper-V with 3 VMs running Win2008 svr and Server2 has Hyper-V with one VM running Win2008 with Terminal Services for RDP users.
We would like to upgrade Server2 host OS to Win2012 R2 and the VM to Win2012 R2. Would there be any repercussion because we'll be mixing Win2008 and Win2012 R2 environment.
Also, I assume we'll require new CAL and RDP client licenses?
