I wanted to upgrade the aegir tools on the -dev and -prod sites. I ran into some problems running the upgrade steps; which are probably due to some mistake I had made in managing the changes made since the original install. During the upgrade process, I was getting a variety of database error messages. I'm assuming that part of the problem was that I had originally installed 0.2, then upgraded to 0.3 and somewhere along the line, upgraded drush. Another symptom I was seeing was that my crontab for aegir was gone, so I could not process tasks.
