How can I upgrade my MSSQL 2008 enterprise to MSSQL 2008 R2? I download the R2 version but it will not take my Key. I want to start taken advantage of Reporting server but cannot connect Report Builder 3.0 because of version issues. Any other options I have? Thank you Roy

Please refer: Upgrading to SQL Server 2008 R2 (http://msdn.microsoft.com/en-us/library/bb677622.aspx) This has detailed procedure for upgrading to SQL Server 2008 R2. A lot of new things with SSRS 2008 R2, What's New (Reporting Services) : http://msdn.microsoft.com/en-us/library/ms170438.aspx Hope this helps!!Chaitanya
