I just upgraded this blog from WP-1.5.2 to WP-2.0.1. There were only a couple of snags - one when the server disconnected me in the middle of the 2.0.1 files being uploaded, nothing major, and also there were some files which I could not overwrite, delete, or rename, so I had to rename their containing folders. But overall, that was slick.

Now I must reactivate some plugins, hoping that they still work with WP2.
