Actually, I was quite worried that I was going to be stuck in the office all day Saturday performing the upgrade, but
in my case the entire process only took
about 2 hours and I didn't run into any issues fortunately. It was an immaculate install. The only hiccup I had was from 5.1 to 6.0 because I transitioned both the databases and the web server to different servers at that time because of the need for .NET 4.0.
Thanks Linda for all your wonderful help. I greatly appreciate your support over the phone and email during this process. It would not have been possible to have such a clean install without your help.
