Ugh!

I tried to update to Drupal 4.7 this evening. It didn't work. I followed the directions, ran the update the script, and the site woulnd't come back up. The script that was supposed to update the database ... didn't. The site came back up with dozens of mysql errors. I played around with it and then tried to back out. That didn't work. Eventually, I had to wipe the database and restore from backups. Sigh... At least now I know enough to be cautious about trying to update any of my "real" drupal sites. :-/
