The SQL Server 2008 Upgrade Technical Reference Guide is now Live and available to download.
It is a 490-page white paper (hold on, do not get scared, you don’t need to read it all :-)) which covers the essential phases and steps to upgrade existing instances of SQL Server 2000 and 2005 to SQL Server 2008 by using best practices.
These include preparation tasks, upgrade tasks, and post-upgrade tasks. It is intended to be a supplement to SQL Server 2008 Books Online.
