MINOR VERSION UPDATES
---------------------
To update from one minor 7.x version of Drupal to any later 7.x version, after
following the instructions in the INTRODUCTION section at the top of this file:

1. Log in as a user with the permission "Administer software updates".

2. Go to Administration > Configuration > Development > Maintenance mode.
   Enable the "Put site into maintenance mode" checkbox and save the
   configuration.

3. Remove all old core files and directories, except for the 'sites' directory
   and any custom files you added elsewhere.

   If you made modifications to files like .htaccess or robots.txt, you will
   need to re-apply them from your backup, after the new files are in place.

   Sometimes an update includes changes to default.settings.php (this will be
   noted in the release notes). If that's the case, follow these steps:

   - Make a backup copy of your settings.php file, with a different file name.

   - Make a copy of the new default.settings.php file, and name the copy
     settings.php (overwriting your previous settings.php file).

   - Copy the custom and site-specific entries from the backup you made into the
     new settings.php file. You will definitely need the lines giving the
     database information, and you will also want to copy in any other
     customizations you have added.

4. Download the latest Drupal 7.x release from http://drupal.org to a
   directory outside of your web root. Extract the archive and copy the files
   into your Drupal directory.

   On a typical Unix/Linux command line, use the following commands to download
   and extract:

     wget http://drupal.org/files/projects/drupal-x.y.tar.gz
     tar -zxvf drupal-x.y.tar.gz

   This creates a new directory drupal-x.y/ containing all Drupal files and
   directories. Copy the files into your Drupal installation directory:

     cp -R drupal-x.y/* drupal-x.y/.htaccess /path/to/your/installation

   If you do not have command line access to your server, download the archive
   from http://drupal.org using your web browser, extract it, and then use an
   FTP client to upload the files to your web root.

5. Re-apply any modifications to files such as .htaccess or robots.txt.

6. Run update.php by visiting http://www.example.com/update.php (replace
   www.example.com with your domain name). This will update the core database
   tables.

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

   - Open settings.php with a text editor.

   - Find the line that says:
     $update_free_access = FALSE;

   - Change it into:
     $update_free_access = TRUE;

   - Once the upgrade is done, $update_free_access must be reverted to FALSE.

7. Go to Administration > Reports > Status report. Verify that everything is
   working as expected.

8. Ensure that $update_free_access is FALSE in settings.php.

9. Go to Administration > Configuration > Development > Maintenance mode.
   Disable the "Put site into maintenance mode" checkbox and save the
   configuration.
