THE CHALLENGE

An Outdated Platform Made Modernization Difficult

The ACS-AEC website was built on Drupal 6 and contained a complex ecosystem of content, users, taxonomies, Webform submissions, files, metadata, and custom functionality. Moving this data to Drupal 10 required more than a standard platform upgrade.

Legacy functionality also needed to be rebuilt for the new Drupal architecture while preserving business logic, data relationships, user access, and existing functionality. The migration had to be carefully managed to protect data integrity and minimize disruption to the organization’s digital operations.

OUR APPROACH

Modernized the Platform Around Data Integrity

We began by auditing the existing Drupal 6 environment and mapping its content structures, users, media, Webforms, taxonomies, custom fields, and functionality before defining the migration roadmap.

The modernization was then built around custom migration scripts, extensive validation, functionality rebuilding, access-control auditing, and a responsive interface designed to retain familiarity for existing users.

I used to spend my mornings scrolling through leads trying to figure out who needed a follow up. Now I just ask the agent, and it tells me with the follow up already drafted.”
