However, you can easily meet Drupal's Composer requirement and be compatible with Pantheon's platform by using Integrated Composer. Composer-managed sites are not compatible with Pantheon's One-click updates. Drupal 8 Composer-Managed SitesĪs of Drupal 8.8, you are required to use Composer to manage your dependencies if you want to use all contributed modules.

Site maintainers can combine these one-click updates with Pantheon's Autopilot service to automate site module updates. Integrated Composer allows you to use one-click core updates through the Dashboard. The latest version of Drupal automatically includes Integrated Composer.

When possible, large site upgrade migrations should be performed locally, where the full system resources can be allocated to the task.This doc includes instructions to make core updates to WordPress and Drupal sites hosted on the Pantheon WebOps platform.

Migrations of particularly large sites to updated Drupal versions can sometimes hit the limits of memory allocated to sites on Pantheon. Troubleshooting Timeouts or Max Memory Errors Otherwise, follow instructions within the Site Dashboard when adding a domain. For details, see Relaunch Existing Pantheon Site. If your source site is on Pantheon and has your domain name pointing to it, you will need to follow special steps to move the domain name to the new site. While this might initially seem like more work, it can often lead to a cleaner result more quickly, especially if your new site includes major architectural changes, features, or a redesign. If you are not having much luck with update.php, consider setting up the new site and using tools like the migrate module to import your existing content. Depending on the specific module stack and configuration of your current site, it may be faster and more direct to plan and execute a content migration to the new site rather than trying to use the built-in update tools. While you can try to get Drupal to handle all the data architecture changes between major revisions (importing the old database and running update.php), this is often not a complete solution. Terminus drush v - migrate-import -all Content and Configuration We have an example repository that shows how all the steps of a migration (from first configuring the migration to running it) can be done with Drush. Scripting migrationsĭepending on the complexity of your site, there is a good chance you will need to script and rerun migrations. See the developer documentation for more details. If needed, you can customize your migration using hooks and plugins. You should review the configuration produced by these migrations by exporting your configuration to yml files ( a best practice for any Drupal site). Content and configurationĭrupal migrations automatically create the needed content types and establish the mappings between the old and new fields by default. Since the latest version of Drupal currently has the same end-user features as Drupal 8.9, and because many contrib modules are not yet compatible with the latest version of Drupal, we recommend that users upgrade their Drupal sites to the latest version of Drupal first. We do not support upgrading to a new major version from within an existing site. WarningIf you have already created a site and want to upgrade it to a new major version, you must start by creating a new site with the new Drupal version you want to use.
