SharePoint – licensing key

When you install SharePoint farm in your environment the only connection between your organization’s license type and license key used during installation of the farm is activation of either Standard or Enterprise features.

The thing is that the only supported change is changing from Standard to Enterprise. There is no supported way of changing from one standard key to another standard key or from one enterprise key to another enterprise key and you can’t downgrade from enterprise to standard. The only supported way is to re-install again!

So folks, please use license key carefully when required as you will loose the option to change it later on after installation.
