In preparation for an eventual upgrade to Drupal 7, today I practiced my Drupal development skills by updating this site from Drupal 6.17 to 6.20. Sure, it was just a minor update but it was also a necessary prelude to the big upgrade to Drupal 7 which I hope to tackle next month. As always, the Drupal documentation made the update process very straightforward. It was really just a matter of backing up the database and all of the Drupal files, and then copying the new files over to the server and running "update.php."
