UPGRADING
---------
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/example.com/settings.php
sites/sub.example.com/settings.php
sites/sub.example.com.site3/settings.php
More information on multisite configuration is located in
the INSTALL.txt file.
2. Disable contributed modules and switch to a core theme
(bluemarine or garland).
3. 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
file (step 8) which can only be run by user ID 1. Do not
close your browser until step 9 is complete.
4. Remove all of the old files and directories from the
Drupal installation directory.
5. Unpack the new Drupal files and directories into the Drupal
installation directory.
6. Copy the backed up files-directory 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
directory as well.
7. Verify the new configuration file to make sure it has the
latest and correct information.
8. (Optional) 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
http://drupal.org/project/Modules for the version of a
module to match your version of Drupal.
9. Run update.php by visiting http://www.example.com/update.php
(replace www.example.com with your drupal installations domain
name). This step will update the database to the new Drupal
installation.
Note: If you are unable to access update.php as user ID 1
do the following:
- With a text editor find the update.php file on your system.
It should be in the main Drupal directory that you installed
all the files into.
- 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;.
Note: Upgrading sequentially is recommended, one release at a time.
It is possible to skip releases, but is not advised.
