Drupal database update

  1. Use this script to upgrade an existing Drupal installation. You don't need this script when installing Drupal from scratch.
  2. Before doing anything, backup your database. This process will change your database and its values, and some things might get lost.
  3. Update your Drupal sources, check the notes below and run the database upgrade script. Don't upgrade your database twice as it may cause problems.
  4. Go through the various administration pages to change the existing and new settings to your liking.
