Enterprise Drupal Migrations: Two Case Studies on Performance, Scale, and Automation

Martin Schlögl of amazee.io shares two in-depth Drupal migration case studies for enterprise clients. The first involved Renesas, migrating a mission-critical Drupal 10 site with zero downtime. Key improvements included Redis caching, backend optimizations, and strict access controls for enterprise-grade security. A collaborative process with Renesas’ developers ensured stability and performance post-migration.

The second project focused on automating the migration of over 180 Drupal multi-sites for a global pharma company. Using Ansible, AWX, and base image workflows, amazee.io achieved rapid, consistent deployments. Secure S3-based data transfer and comprehensive documentation minimized client effort while supporting long-term maintenance. Built on Lagoon, the platform improved developer experience with faster, controlled releases.

Both examples highlight best practices: early technical discovery, automation at scale, and investing in clear, useful documentation. The article effectively positions migrations as strategic upgrades, not just technical chores. It offers practical insights for large-scale Drupal operations and modernization.
