Files Changed by Drupal Upgrades

Upgrading Drupal

Drupal recommends taking the following steps to upgrade to the latest version of Drupal:

• Backup your database and Drupal directory - especially your configuration file in 'sites/default/settings.php'.
• Log on as the user with user ID 1.
• If you are upgrading to a new major release (ie. 5.x to 6.x), you may want to disable contributed modules (leave only core modules on) and put your site "offline" while upgrading.
• Remove all the old Drupal files then unpack the new Drupal files into the directory that you run Drupal from.
• Modify the new configuration file to make sure it has the latest and correct information.
• Run update.php by visiting http://www.example.com/update.php.

This process upgrades all the core Drupal files, including ones that may not have changed in minor updates. For this reason, we are going to list version-specific files that have changed for those wishing to simply update the necessary files. This is how we update our Drupal installations. In other words, we simply replace the files that were updated, and run update.php. This achieves the same result as removing all the old files and replacing them by all the new ones, as long as you carefully observe which versions of Drupal you are upgrading. While we've done our best to maintain their accuracy, we do not guarantee the correctness of these lists, and will not be held responsible for any problems you encounter as a result of their use. If unsure, please follow the official upgrade instructions included in your distribution's download. Remember to check your changelog file (in root directory) to see which version of Drupal your site is currently running.

Request Older Revisions

Because it takes more time than we have to post revisions for all previous Drupal versions, we are currently only posting a list of files changed by the latest update, plus specific revisions requested by users.
