"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

That is the known procedure. and it works on NON OEM software (I don't have any OEM software.. everything here is volume center.

While an OEM version CAN be upgraded, an OEM version cannot be used to upgrade - attempting to enter an OEM key as your "upgrade" should fail.

Should fail? Can anyone give a more definitive answer? When we do a "/Get-TargetEditions" it shows that Enterprise is an option...
Lee W, MVPTechnology and Business Process AdvisorCommented:
Ok - the licensing answer is you can't do it.  We can't help you violate licensing.  OEM copies cannot be used to upgrade.  Not should not - CANNOT.  because of this, your answer is you can't do that.
