SQL Server 2008 Upgrade Lab at Microsoft

Tools
I got an invite to take part in a lab at the Microsoft Technology Center in Waltham. I took advantage of it. I'll use this post to describe the experience so that anyone else with the opportunity will know what to expect.  [caption id="attachment_333" align="alignnone" width="450" caption="They knew I was coming"] [/caption] First, you recieve a very explicit set of pre-requisites.
