Hey guys. Have a quick question. I have a Primery SCCM 2012 R2 SP1 on a Serv08 R2. Can I do a windows 2012 R2 upgrade. Would SCCM would be affected. SQL is local on same server as sccm version 2012. Can someone guide me to the right steps. SCCM is a VM on Hyperv 2012. This is not a CAS and I have about 4 secondary sites with serv08 R2. Thanks
