Change Windows 2012 Server Edition

Posted by Alan McBurney on April 8, 2013


Just started a new project today for a customer where I will be building a 2 node DAG on Server 2012.

Got the Exchange server bits installed and then tried creating the DAG which failed.

After a bit of analysis it transpires that the customer built the base OS with Windows 2012 Standard and not DataCenter (Server 2012 doesn’t include an Enterprise Edition any more)

Luckily we can convert between editions of Windows Server on the fly via DISM (Deployment Image Service & Management)

TechNet documentation on converting between server 2012 versions can be found here

To determine the current edition of Windows Server installed run the following

  • DISM /online /Get-CurrentEdition

To determine which versions the server can be upgraded to run

  • DISM /online /Get-TargetEditions

As can be seen from the above screenshot this version of Windows Server can be upgraded to Target Edition : ServerDatacenter

To complete the conversion between editions we use the DISM command with the following format

  • DISM /online /Set-Edition:<Version> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEULA

In the above example the target edition is ServerDatacenter

A reboot of the server and a check of the server edition reveals that is has indeed been successfully upgraded to DataCenter

  1. Unfortunately if the server is a domain controller, you have to first migrate roles and demote it before you can change the version.

    Would this work to move a 2012 Data Center Server down to a 2012 Standard Server?
