I'm currently trying to upgrade an instance of SQL Server 2005 Standard 64bit Edition to SQL Server 2008 R2 Standard Edition. The issue I believe that I am having is that the SQL Server 2008 R2 media is MSDN as this has been re-purposed as a test server. Is it possible to upgrade from a fully licensed version of SQL Server to an MDSN license?
The error message that I'm getting during the installation is: - "Rule SQL Server 2008 R2 Feature Upgrade Failed" - The specified upgrade edition is not support.
Does anyone know if I'm on the right tracks with my guess?
