Can Windows 2012 OEM be upgraded to Windows 2012R2?

Question

Windows Server

We bought an HP 380 gen 8 server. It came with Windows 2012. Can it be upgraded to 2012 R2? I downloaded the original image of Windows 2012 R2, the language is the same. At the stage of entering the key - an error (We were unable to verify the product key)

Answer 1

Windows 2012 OEM to Windows 2012R2

There are no such products. There is Windows Server 2012 and Windows Server 2012R2, not the edition you specified. These are separate products. Buy a 2012R2 and the key will fit.
