We had to move an oem server installation of WS 2012 R2 to a virtual machine on another server because of hardware failure. Of course now its not activated. We have short term plans (about 1 year out to upgrade to a newer version of windows server but we need to activate this version on the VM unitil then and are wiling to incur the cost. My trouble is that I cannot find where to purchase a valid WS 2012 R2 license. Can you please advise?
