Changing Windows Server 2012 R2 from Standard to DataCenter Edition

First set is to verify the edition of Window Server 2012 R2.

You can check this with the GUI at Control Panel\System and Security\System

or via the following command line:

dism.exe /online /Get-CurrentEdition

Next lets verify that the install of Windows can be migrated to a different version

dism.exe /online /Get-TargetEditions

We’ve confirmed that this installation can be migrated to DataCenter Edition, now we need to set the installation edition. This change requires acceptance of the End User Agreement and the Windows DataCenter Edition KMS setup key.

dism.exe /online /Set-Edition:ServerDatacenter /AcceptEula /ProductKey:W3GGN-FT8W3-Y4M27-J84CP-Q3VJ9

The server will require a reboot for this change to take effect.

To verify the Edition has been changed:

dism.exe /online /Get-CurrentEdition

Now the Server can be activated as a Windows Server 2012 R2 DataCenter server.
