In my student years, I got several [legal, of course! :-)] WS2012 product keys and disk images, of several generations and editions:
"R2 With Update" generation
What I would like to know is this:
can I use any/all of my 2012-original and R2 keys with their respective R2-With-Update disk images? if yes but not all, then which ones?
can I use any/all of my 2012-original keys with their respective R2 disk images? if yes but not all, then which ones?
Of course, I`m also curious to know whether or not the later keys are also backwards compatible -- i.e. R2WU keys with R2 and original, and/or R2 keys with original -- but this is not nearly as important as the preceding questions [in bullet-points]. ;-)
FYI, I already found windows-server-2012-r2 and Windows_Server_2012_R2_Licensing_Datasheet.pdf and Windows_Server_2012_R2_Remote_Desktop_Services_Licensing_Datasheet.pdf and WindowsServer2012R2_Licensing_Guide.pdf, but I didn`t find what I was looking for in any of that.
