Case Study — Controlled Migration to Drupal 11

Demonstrative case study

Demonstrative case study: migration to Drupal 11 with audit, SEO preservation, content takeover and a clear maintenance path.

Context

An aging Drupal platform carried important content, several languages and technical dependencies that had become difficult to maintain. The team needed to modernize without losing editorial and SEO value.

Problem

Technical debt slowed down changes, modules had to be assessed and public aliases could not be treated as a secondary detail.

Solution

The project started with an inventory of content, modules, risks and URLs. The migration was then organized in batches, with validation before writing, dry-runs and continuity for important journeys toward Drupal migration, Drupal maintenance and Drupal audit.

Stack

  • Drupal 11, PHP 8.4 and MariaDB.
  • DDEV for local validation.
  • Drush, Composer, Content Sync and quality checks.

Results

  • Migration framed around real risks.
  • Better protected SEO continuity.
  • More predictable future maintenance.
