Drupal database update

Use this utility to update your database whenever a new release of Drupal or a module is installed.

For more detailed information, see the upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.

Back up your code. Hint: when backing up module code, do not leave that backup in the 'modules' or 'sites/*/modules' directories as this may confuse Drupal's auto-discovery mechanism.
Put your site into maintenance mode.
Back up your database. This process will change your database values and in case of emergency you may need to revert to a backup.
Install your new files in the appropriate location, as described in the handbook.

When you have performed the steps above, you may proceed.
