Drupal 10 to 11 Upgrade Guide: Six-Step Migration Process

Joshi Consultancy Services outlines the benefits of upgrading a Drupal site from version 10 to 11, including stricter API controls for better security, optimized caching for faster performance, and new features such as CKEditor 5 autoformatting and Symfony 7 support. The guide notes that Drupal semantic versioning ensures smoother major upgrades and stresses backing up codebases, databases and files, updating to Drupal 10.3 or newer, auditing hosting requirements and removing unused modules to streamline the process.

The article describes checking module and theme compatibility with the Upgrade Status plugin and Drupal Rector tools, setting up a separate staging environment, running Composer commands to update core packages, performing Drush database updates and configuration exports, and restoring file permissions after the upgrade. It recommends testing key site functions across browsers and devices and offers troubleshooting advice for composer conflicts, missing modules and caching performance issues.

The clear structure and practical code examples equip developers to minimize risk and downtime during the upgrade, though the content assumes command line proficiency and familiarity with Linux environments. The absence of instructions for Windows or macOS systems and lack of performance benchmarks or visual diagrams may limit its usefulness for some readers.
