Upgrade edition in-place are possible as from Windows 7 and 2008 R2

As from Windows 7 and 2008 R2 it is possible to upgrade edition in-place using the DISM utility. However you can’t downgrade, it’s 1 way only.

Possible upgrade paths are:

– Windows Server 2008 R2 Standard -> Windows Server 2008 R2 Enterprise -> Windows Server 2008 R2 Datacenter
– Windows Server 2008 R2 Standard Server Core -> Windows Server 2008 R2 Enterprise Server Core -> Windows Server 2008 R2 Datacenter Server Core
– Windows Server 2008 R2 Foundation -> Windows Server 2008 R2 Standard

You can’t perform the operation on a DC, to accomplish this on a DC, you need to transfer FSMO roles (if applicable), demote it, reboot, upgrade, reboot, promote it, reboot.

To determine the installed edition, run:
DISM /online /Get-CurrentEdition

To check the possible target editions, run:
DISM /online /Get-TargetEditions

Finally, to initiate an upgrade, run:
DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Reboot at the end to activate the change.

 

EDIT 24-03-2012: I recently had the problem that the command returned "1605" error stating that the product key entered wasn’t correct, however the key was valid. Solution was: upgrade using a KMS key (see Microsoft website for those) and afterwards change product key to the final key.
