Chapter Upgrading your site

Upgrading your Drupal site whether for a point release or a full release follows the same basic steps.

1. Backup your database and Drupal directory - especially your "sites" directory which contains your configuration file and added modules and themes, any contributed modules in your "modules" directory, and your "files" directory which contains uploaded files.

Note: for a single site setup the configuration file is the "settings.php" file located at sites/default/settings.php. For multisite configuration the configuration file is located in a structure like the following:

sites/default/settings.php sites/ sites/ sites/

More information on multisite configuration is located in the INSTALL.txt file.

2. Log on as the user with user ID 1. User ID 1 is the first account created and the main administrator account. User ID 1 needs to be logged in so that you can access update.php (step 9) which can only be run by user ID 1. Do not close your browser until step 10 is complete.

3. Place the site in "Off-line" mode, to mask any errors from site visitors.

4. Disable contributed modules and switch to a core theme (Blue Marine or Garland).

5. Remove all of the old files and directories from the Drupal installation directory.

6. Unpack the new Drupal files and directories into the Drupal installation directory.

7. Copy the backed up "files" and "sites" directories to the Drupal installation directory. If the original .htaccess or robots.txt files have been modified, copy the backed up versions of these files to the installation directory as well.

8. Verify the new configuration file to make sure it has the latest and correct information.

9. Re-install contributed modules.


Note: make sure the version of a module matches your version of Drupal. Modules from previous versions may not be compatible with the current version. Check for the version of a module to match your version of Drupal.

10. Run update.php by visiting (replace with your Dru-pal installation's domain name and path). This step will update the database to the new Drupal installation.

Note if you are unable to access update.php do the following:

Open update.php with a text editor. - There is a line near top of update.php that says $access_check = TRUE;. Change it to $access_check = FALSE;. - As soon as the script is done, you must change the update.php script back to its original form to $access_check = TRUE;.

11. Finally, return site to "Online" mode so your visitors may resume browsing.
