I have a SharePoint 2010 Trial install, I'm trying to upgrade the license type to Enterprise, but am running into an error and cannot determine any details.

I go to the upgrade and migration section, choose convert farm license type, and enter my license key. When I submit the page, I receive the error "The product key could not be validated. Check the error logs for details."

  1. I looked all throughout my ULS logs, but cannot find any error message. I see a few references to _admin/conversion.aspx, but no reference to any error messages
  2. I restarted IIS, and even the server, but I still receive the same error

Can anyone help? Perhaps I'm looking in the wrong location for my error logs? Has anyone run into this before?

You can't upgrade from a Trial to an Enterprise license. You need to upgrade to a Standard CAL first, then upgrade that to an Enterprise.

Excerpt from http://msdn.microsoft.com/en-us/subscriptions/cc263204(v=office.14).aspx:

You cannot upgrade directly from a Standard trial version to an Enterprise licensed version. You must upgrade to the Enterprise trial version first. Follow the steps in this article to upgrade to the Enterprise trial version and then to the Enterprise licensed version, and then follow the steps in the following article to enable the Enterprise features: Upgrade from a SharePoint Server 2010 Standard CAL to an Enterprise CAL.

  • did you get the trial install to upgrade correctly? Keep us updated!

  • Yep! I had to do just what was mentioned in the article and go from Standard Trial to Standard Licensed, and then Std Lic to Enterprise Lic.
