Upgrade Windows 2008 R2 Standard to Enterprise or DataCenter

I had a virtual 2008 R2 Standard server that I upgraded memory on to 64GB and realized (forgot) that it only supported up to 32GB RAM. Here’s what I did to upgrade to DataCenter to overcome the 32GB limitation.

To determine the installed edition, run:

DISM /online /Get-CurrentEdition

To check the possible target editions, run:

DISM /online /Get-TargetEditions

To Start upgrade;

DISM /online /Set-Edition: /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
