Upgrading WS2008R2 Standard to Enterprise

Already installed the standard version but need to get clustering etc working?

As I seem to try to find these instructions so often and they are spread around the place I decided to summarize them here:

1. Start an administrative command prompt (UAC elevated)
2. Run the following command:

DISM /online /Set-Edition:ServerEnterprise /productkey:AAAAA-BBBBB-CCCCC-DDDDD-EEEEE

You can try to use your own key but as it often doesn’t work you can use this general key: 489J6-VHDMP-X63PK-3K798-CPX3Y temporarily

After the restart (this takes a while) run the following commands to change your own key back:

1. Type in slmgr.vbs -ckms (this clears any KMS entry you may have)
2. Type slmgr.vbs -upk (this removes any product key installed)
3. Type slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (where the x’s is the new product key you want to use )
4. Type slmgr.vbs -ato (this activates the server)

Done!
