Drupal Migration &
Upgrade Services

We migrate and upgrade Drupal platforms with code-level precision, stable architecture, and zero data loss. At Melity, we manage Drupal transitions with structured planning, compatibility reviews, and full-stack readiness. Whether moving from legacy systems or upgrading to the latest Drupal release, our process ensures data integrity, performance continuity, and module compatibility — all without disruption to your platform logic or business operations.
