CodeLift migrated NHG Referentiemodel’s healthcare IT platform from Drupal 7 to Drupal 10, focusing on data integrity, compliance, and uninterrupted access to critical medical coding tools.
The process began with a review of the legacy database, viewers, and reference tools used in healthcare workflows. AI-assisted migration pipelines were built using the Drupal Migrate API to transform structures, migrate data, and preserve existing business logic. Access to coding tables, APIs, and online viewers was maintained throughout the process.
Staged rollouts mirrored the production environment, with full functionality tested before switch-over. Automated screenshot comparisons, table audits, and manual reviews by healthcare professionals ensured visual and functional accuracy.
The result was a complete Drupal 10 platform with verified data parity across 100+ coding tables, less than one hour of downtime during cutover, and fully preserved functionality for all medical reference tools.
