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.

    Hi Bart,

    Is it possible to use the DISM to do an in-place upgrade from Windows Server 2008 R2 Enterprise OEM to Windows Server 2008 R2 Datacenter Edition using a VLK?

    Regards,

    David.

    Never did that and I’m unable to test it. However the install media is no longer specific, in the past it was. Only the product key counts. Based on that information I would say it is possible from technical point of view… Regarding license policy I have no idea if it’s “ethical” to do.

    Hi Bart,

    Thanks for you response. We purchased this server with the OEM Enterprise Edition preinstalled. As far as “Regarding license policy I have no idea if it’s “ethical” to do.” As long as I am legally licensed to run Datacentre, through the VLK purcahsed for this server; I’m not sure what ethical dilema you are referring to?

    Regards,

    David.

      If you have purchased the licenses I don’t see any issue. Sorry about confusion regarding “Ethical”, I misread…
