As I was preparing for some labs, I decided to see if there were any updates for Upgrade Advisor.  There is a new version as of April 18th.  Be sure to grab this latest version as you prepare to Upgrade to SQL Server 2005.  If you haven't heard about Upgrade Advisor, it is a free download from www.microsoft.com/sql that analyzes the meta data in your database for possible issues.  It is very good.  It even allows you to specify a trace file to analyze so that you will know what issues that may appear from your application.  This tool is updated occasionally and I cannt tell a difference from the January version from my brief experience with this tool this past week.
