   3  UPGRADING
   4  ---------
   5  
   6  1.  Backup your database and Drupal directory - especially your
   7      "sites" directory which contains your configuration file and
   8      added modules and themes, any contributed modules in your
   9      "modules" directory, and your "files" directory which contains
  10      uploaded files.
  11  
  12      Note: for a single site setup the configuration file is the
  13      "settings.php" file located at sites/default/settings.php.
  14      For multisite configuration the configuration file is located
  15      in a structure like the following:
  16  
  17        sites/default/settings.php
  18        sites/example.com/settings.php
  19        sites/sub.example.com/settings.php
  20        sites/sub.example.com.path/settings.php
  21  
  22      More information on multisite configuration is located in
  23      the INSTALL.txt file.
  24  
  25  2.  Log on as the user with user ID 1.  User ID 1 is the first
  26      account created and the main administrator account.  User
  27      ID 1 needs to be logged in so that you can access update.php
  28      (step 9) which can only be run by user ID 1.  Do not close
  29      your browser until step 10 is complete.
  30  
  31  3.  Place the site in "Off-line" mode, to mask any errors from
  32      site visitors.
  33  
  34  4.  Disable contributed modules and switch to a core theme
  35      (Bluemarine or Garland).
  36  
  37  5.  Remove all of the old files and directories from the Drupal
  38      installation directory.
  39  
  40  6.  Unpack the new Drupal files and directories into the Drupal
  41      installation directory.
  42  
  43  7.  Copy the backed up "files" and "sites" directories to the
  44      Drupal installation directory. If the original .htaccess or
  45      robots.txt files have been modified, copy the backed up
  46      versions of these files to the installation directory as
  47      well.
  48  
  49  8.  Verify the new configuration file to make sure it has the
  50      latest and correct information.
  51  
  52  9.  Re-install contributed modules.
  53  
  54      Note: make sure the version of a module matches your
  55      version of Drupal.  Modules from previous versions may
  56      not be compatible with the current version.  Check
  57      http://drupal.org/project/Modules for the version of a
  58      module to match your version of Drupal.
  59  
  60  10. Run update.php by visiting http://www.example.com/update.php
  61      (replace www.example.com with your drupal installation's
  62      domain name and path).  This step will update the database to
  63      the new Drupal installation.
  64  
  65      Note: if you are unable to access update.php do the following:
  66  
  67        - Open update.php with a text editor.
  68  
  69        - There is a line near top of update.php that says
  70          $access_check = TRUE;. Change it to $access_check = FALSE;.
  71  
  72        - As soon as the script is done, you must change the update.php
  73          script back to its original form to $access_check = TRUE;.
  74  
  75  11. Finally, return site to "Online" mode so your visitors may resume
  76      browsing.
