Upgrade Windows Server 2012 Standard Edition to Datacenter Edition

Do I need to reinstall Windows if I want to upgrade my existing Windows Server 2012 Standard Edition to Datacenter Edition?

The answer is: No.¬†You don’t have to reinstall.

All you need is a licensing change. I’m assuming you have purchased the datacenter license or you have volume licensing.

Step 1 – Determine Upgradability

DISM /online /Get-TargetEditions

Step 2 – Provide Datacenter License Key

DISM /Online /Set-Edition:ServerDatacenter /AcceptEula /ProductKey: (put your datacenter key here)

Step 3 – Reboot
Restart, and you’ll have a successfully upgraded machine.
