Current server is Windows 2008 r2 Standard (oem Dell) Workgroup server, not on an Active directory.
Challange: I would like to upgrade it to enterprise.
What I tried:
At first I got on ebay a product key a key code for enterprise.
I ran "Dism /online /Set-Edition:ServerEnterprise /ProductKey:xxxx-xxxxx-xxxxx-xxxxx-xxxxx" from a command prompt and I got an error that "get-targeteditions option is unknown".
I assumed that the reason im getting that message is because I have standard r2 but the enterprise was not r2. So I returned it and got another key for R2. When I tried to install it the same way as before (dsim, etc) I got a different message "the specified product key is not valid for the target edition".
The reason its not working is because I have OEM software and I have to get a specific version that would work with this specific standard server. The big question is, WHICH ONE? should I get a dell oem enterprise key? a boxed one from M$? Or is there something else I dont know?
Microsoft wont answer me as they want me to buy 2012... Im not ready for that. They dont sell 2008.
Anybody with some knowledge as to what I need to get please let know!
