I’d been looking at how to upgrade our Windows 2000 machines to XP at work recently, without losing all the data on them. We would normally just reimage them, and put up with the lost data, but that seemed awfully heavy handed. Nobody on the web seemed to have detailed how to do it with Zenworks, so I came up with my own method. In the process of writing it up for our wiki, I put on the web for others to use as a resource should they need it.
