I have a windows server running an OEM (off the shelf boxed copy) of SQL 2008 Standard. I need to upgrade this copy to SQL 2008 R2, which I will be doing using downgrade rights from a copy of SQL 2014 Standard that I have through Volume License.
All of the references I have found point to the upgrade process needing a product key for installation, which is not provided in the VLSC. Has anyone had experience using the 2008 to 2008 R2 upgrade tool in the SQL Server 2008R2 installer to perform this? I called Microsoft and they said that I would need to uninstall the OEM copy and install the volume license copy fresh, which will not prompt for a product key.
Any assistance is greatly appreciated.
