Upgrade Drupal

NOTE: It is advisable to create a backup before starting the update process. If you have important data, create and try to restore a backup to ensure that everything works properly.

Put your site into maintenance mode

  • Log in to the Drupal administration panel.

  • Browse to the “Administration -> Configuration -> Development -> Maintenance mode” section. Enable the “Put site into maintenance mode” checkbox and save the configuration:

Drupal Maintenance mode

Enable the Maintenance mode

  • Disable the maintenance mode when the upgrade is finished.

Upgrade Drupal

You can update Drupal core with a minor version change using Composer, a dependency management tool and drush, a command-line shell and scripting interface for Drupal. Both tools are already included in Bitnami Drupal Stack. To upgrade Drupal, follow the steps below:

  • Change your working directory to the Drupal application:

      $ cd /opt/bitnami/drupal/

  • Upgrade the application with Composer and drush by executing the commands below:

      $ drush cache:rebuild
  $ sudo composer update drupal/core-recommended --with-dependencies
  $ drush updatedb
  $ drush cache:rebuild

  • Check that the application has been successfully updated:

      $ drush core:status

  • Restore any persisted file under /bitnami/drupal if necessary.
