I have a 2008 R2 server that I licensed using my MAPS subscription long ago. I still have MAPS but older versions of Windows Server are not available, only the latest are available for DL.
I can&#39;t seem to upgrade 2008 R2 using the 2012 eval ISO as it says upgrade from retail to trial version is not supported.
How can I upgrade my 2008 R2 server?? I need to get to at least 2012 (or beyond).
Thanks for any help.
