As of my last knowledge update in September 2021, Drupal 10 had not been released yet. However, I can provide you with some general information on how to approach upgrading from Drupal 9 to Drupal 10, based on typical practices for upgrading between major versions of Drupal.
Keep in mind that the information might have changed since then, so I recommend checking the official Drupal website or relevant resources for the most up-to-date information.
When upgrading from Drupal 9 to Drupal 10, you would typically follow these steps:
- Check Compatibility: Before upgrading, ensure that your current Drupal 9 website is using compatible modules, themes, and custom code. Some contributed modules might not be ready for Drupal 10 immediately after its release.
- Update Core and Modules: Make sure your Drupal 9 installation is up-to-date with the latest stable release. Update all contributed modules and themes to their latest compatible versions as well.
- Audit Custom Code: Review and update your custom code to ensure it is compatible with Drupal 10. API changes and deprecated functions may affect your custom code.
- Prepare the Testing Environment: Set up a testing environment that mirrors your production site. This allows you to test the upgrade process and identify any issues before applying changes to the live site.
- Upgrade Core: Follow the official upgrade documentation provided by Drupal when Drupal 10 is released. Typically, you would replace the core files with those from the Drupal 10 release and run the necessary database updates using the update script.
- Update Modules and Themes: Once Drupal core is upgraded, work on updating your contributed modules and themes to their Drupal 10 versions. Some modules might have undergone significant changes, so make sure to read their release notes and documentation.
- Test and Debug: Thoroughly test the upgraded site in the testing environment. Test functionality, content display, forms, user interactions, and any custom features. Address any issues that arise during testing.
- Migrate Content and Configuration: If necessary, use the appropriate migration tools to transfer content and configuration from the Drupal 9 site to the Drupal 10 site.
- Theme Updates: If your theme is custom-built, make sure it is compatible with Drupal 10. Update the theme as needed to ensure proper rendering and responsiveness.
- Deployment: Once the testing is successful, schedule a maintenance window to apply the updates to the live site. Back up your live site and database before making any changes.
- Post-Upgrade Testing: After the upgrade on the live site, thoroughly test all functionality again to ensure everything is working as expected.
- Monitor and Maintain: Keep an eye on the site's performance and functionality post-upgrade. Address any issues that arise promptly.
