Enable the "Put site into maintenance mode" checkbox and save the
configuration.
-3. Remove the 'core' and 'vendor' directories. Also remove all of the files
- in the top-level directory, except any that you added manually.
+3. Determine if your project is managed by Composer.
- If you made modifications to files like .htaccess, composer.json, or
- robots.txt you will need to re-apply them from your backup, after the new
- files are in place.
+ On a typical Unix/Linux command line, this can be determined by running the
+ following command (replace /PATH/TO/composer with the appropriate location
+ for your system):
+
+ /PATH/TO/composer info drupal/core
+
+ If this is successful, your project is managed by Composer.
+
+ If you don't have Composer installed or access to the command line, you can
+ check the contents of composer.json. If "drupal/core" is present in the
+ "require" section of your composer.json file, then the project is managed by
+ Composer.
+
+ If the project is not managed by Composer, follow the steps under "UPDATING
+ CODE WITHOUT COMPOSER", otherwise go to "UPDATING CODE WITH COMPOSER".
+
+UPDATING CODE WITH COMPOSER
+---------------------------
+1. On a typical Unix/Linux command line, run the following command from the root
+ directory (replace /PATH/TO/composer with the appropriate location for your
+ system):
+
+ /PATH/TO/composer update
+
+ Note, if Composer is not installed you will need to install it in order to
+ update Drupal.
+
+ Note, if you want to only update drupal/core the following command will
+ probably work:
+
+ /PATH/TO/composer update drupal/core symfony/* --with-all-dependencies
+
+2. Check the release notes for the updated version of Drupal to find out if
+ there is a change to default.settings.php.
+
+ You can find the release notes for your version at
+ https://www.drupal.org/project/drupal. At bottom of the project page under
+ "Downloads" use the link for your version of Drupal to view the release
+ notes. If your version is not listed, use the 'View all releases' link. From
+ this page you can scroll down or use the filter to find your version and its
+ release notes.
- 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:
+ If there is a change to default.settings.php, follow these steps:
- Locate your settings.php file in the /sites/* directory. (Typically
sites/default.)
database information, and you will also want to copy in any other
customizations you have added.

+3. Determine if there are any modifications to files such as .htaccess or
+ robots.txt and re-apply them. The Drupal Scaffold composer plugin
+ (https://github.com/drupal-composer/drupal-scaffold) can help you with
+ excluding files you'd like to always preserve when updating Drupal.
+
+4. Go to the "UPLOADING THE CODE" section
+
+UPDATING CODE WITHOUT COMPOSER
+------------------------------
+1. Remove the 'core' and 'vendor' directories. Also remove all of the files
+ in the top-level directory, except any that you added manually.
-4. Download the latest Drupal 8.x.x release from https://www.drupal.org to a
- directory outside of your web root. Extract the archive and copy the files
- into your Drupal directory.
+ If you made modifications to files like .htaccess, composer.json, or
+ robots.txt you will need to re-apply them from your backup, after the new
+ files are in place.
+
+ This should leave you with the modules, profiles, sites, and themes
+ directories. These directories should only contain code that you've used to
+ extend Drupal.
+
+2. Download the latest Drupal 8.x.x release from https://www.drupal.org/download
+ to a directory outside of your web root. Extract the archive and copy the
+ files into your Drupal directory.
+
+ Copy all the files, but do not accidentally overwrite your modules, profiles,
+ sites, or themes directories.
On a typical Unix/Linux command line, use the following commands to download
and extract:
cp -R drupal-x.y.z/* drupal-x.y.z/.htaccess /path/to/your/installation
If you do not have command line access to your server, download the archive
- from https://www.drupal.org using your web browser, extract it, and then use
- an FTP client to upload the files to your web root.
+ from https://www.drupal.org using your web browser and extract it locally.
+
+3. Check the release notes for the updated version of Drupal to find out if
+ there is a change to default.settings.php.
+
+ You can find the release notes for your updated version at
+ https://www.drupal.org/project/drupal. At bottom of the project page under
+ "Downloads" use the link for your updated version of Drupal to view the
+ release notes. If your updated version is not listed, use the 'View all
+ releases' link. From this page you can scroll down or use the filter to find
+ your updated version and its release notes.
+
+ If there is a change to default.settings.php, follow these steps:
+
+ - Locate your settings.php file in the /sites/* directory. (Typically
+ sites/default.)
+
+ - Make a backup copy of your settings.php file, with a different file name.
-5. Re-apply any modifications to files such as .htaccess, composer.json, or
- robots.txt.
+ - 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. 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
+ If you have added requirements in composer.json, it is recommended that you
+ re-add the requirements using Composer instead of applying the changes by
+ hand. For example, on a typical Unix/Linux command line, to reinstall the
+ Address module and its dependencies run (replace /PATH/TO/composer with the
+ appropriate location for your system):
+
+ /PATH/TO/composer require drupal/address
+
+ If you do not have command line access to your server, you will need to run
+ the Composer commands locally before uploading the file system to your
+ server.
+
+5. Go to the "UPLOADING THE CODE" section
+
+UPLOADING THE CODE
+------------------
+1. If you updated the code in a different environment from where it is running
+ you need to upload the files to your web root including the vendor/
+ directory.
+
+2. Go to the "UPDATING THE DATABASE" section
+
+UPDATING THE DATABASE
+---------------------
+1. 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.
- Once the update is done, $settings['update_free_access'] must be reverted
to FALSE.
