EDF Energy Consolidates Six Websites in Drupal 10 Migration Project

Moving multiple enterprise websites to a new major Drupal version required EDF Energy to reassess both its technical platform and its publishing workflows. In a case study published by Drupal agency ComputerMinds, the organisation describes how it rebuilt and migrated six websites to Drupal 10 while using the transition as an opportunity to review functionality that had accumulated over the previous five years.

The project is relevant to the wider Drupal ecosystem because it illustrates how major version upgrades can be combined with platform rationalisation efforts. Stakeholders reviewed existing features to determine which would be retained, redesigned, or removed, with usage data and analytics informing some of those decisions. The case study describes a process focused on simplifying the platform rather than reproducing legacy functionality unchanged.

EDF Energy also migrated content into a new structure. The published account states that custom automations were used to support the migration and help ensure content displayed correctly within the new system. The source additionally notes that the old and new sites operated in parallel during testing and review phases, allowing editorial teams to evaluate migrated content before launch. However, no technical details are provided about the migration tooling, workflows, content architecture, or implementation approach.

The case study reports positive results from internal customer testing and describes the migration as a successful project outcome. However, it does not disclose benchmark data, testing methodology, sample sizes, or comparative performance figures, limiting independent assessment of the reported results. As presented, the project demonstrates how organisations can use Drupal upgrades to review content structures, workflows, and accumulated functionality alongside platform changes.
