In my last post on SQL Server 2005 I mentioned that SQL Server 6.5, 7.0 and 2000 are no more supported on Longhorn and Vista and I recommend to prepare for an upgrade to SQL Server 2005 with SP2.

And now a good news for all of them who are running on earlier versions. Microsoft has published a technical whitepaper on "SQL Server 2005 Upgrade Technical Reference Guide" which could be used as a reference to successfully upgrade from earlier versions. This 360 pages lengthy document covers the Backward compatibility issues to Clustering to Security considerations.

A must read.
