Upgrade Windows Server 2012 Essentials to Windows Server 2012 R2 Standard

There is no direct upgrade path from Windows Server 2012 Essentials to Windows Server 2012 R2 Standard. These are the steps I performed as a workaround:

Transition to Windows Server 2012 Standard

Open Windows PowerShell as Administrator, and then run the following command.

dism /online /set-edition:ServerStandard /accepteula /productkey:Product Key

Where Product Key is the product key for your copy of Windows Server 2012 Standard.

The server restarts to finish the transition process.

6 thoughts to “Upgrade Windows Server 2012 Essentials to Windows Server 2012 R2 Standard”

  1. I am thinking about heading this direction since I would like to take advantage of the R2 features of Server 2012 on my 2012 Essentials server. When you enable the Server Essentials Experience Role on Standard 2012 R2, does it make the server act like Essentials again, whereby you have to connect the client computers via the Connector software or can computers be joined just by changing the domain info? Trying to weigh the pros and cons of doing an in place migration to get to 2012 R2. Just wish you could have did an in place upgrade from 2012 Essentials to 2012 Essentials R2. What are your thoughts? Was it worthwhile to do this upgrade path? Any issues you have ran into since upgrading to 2012 Standard R2? Just don’t have the time, energy or hardware to build a replica domain to migrate everything over.

    1. Hi Dan, when you enable the role it doesn’t limit the functionality to just essentials. You can still join client computers to the domain as usual.

      I didn’t run into any issues but I’m no longer running essentials and just have a 2012 R2 Standard domain.

  2. Ok cool. I’ll give it a try upgrading my Essentials to Standard R2 via your instructions. I just didn’t want to run into any unforeseen issues. Hopefully it goes as smooth for me as it did for you.

    Thanks again!

  3. Thanks for your article. I would like to keep essentials as is and just have the option to register more than 25 users. Can I just upgrade the license with the command dism /online /set-edition:ServerStandard /accepteula /productkey:Product Key and not installing anything from the Standard install media?

    Thanks.
