Windows 2012 Datacenter downgrade


I have build a Windows 2012 DC cluster now I found out that It supposed to be a Standard edition with only one VM on it.

Is there any way I can downgrade from Windows 2012 Datacentre to Standard?

I have tried
DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX


slmgr -upk (this removes the current Product Key)

slmgr -ipk XXXX-XXXX-XXXX-XXXX (this installs the new Product Key)
but no success.

Please help.

Thank you

Hi Sushil,

Thanks for your reply.
I have seen both links & one link is a year old and other is Jan 2013. I was wondering if Microsoft or anybody come out any other way to resolve this problem? ;-)

Need to reinstall

You can contact OEM.  If you have a HP system then check this link
