The AI-First Enterprise Migration Playbook: Legacy CMS to Drupal 11

FAQs

 

Most migration guides focus on the technical execution of moving content between platforms. This playbook focuses on the decisions that precede execution, specifically the scoping, governance, and organizational readiness decisions that determine whether a migration succeeds or fails before a line of code is written. The central argument is that most enterprise migrations fail during scoping, not execution, and the framework is structured around that claim.

 

 

It means treating migration as the prerequisite for AI readiness rather than a standalone infrastructure project. Drupal 11's API-first architecture and structured content model make it possible to connect content to intelligent search, personalization engines, and automated workflows. Legacy CMS architectures, tightly coupled, monolithic, built before API-first design was standard, cannot support those capabilities regardless of the tools layered on top of them. A migration done well positions the organization to act on AI investments it is likely already making. A migration done poorly, or deferred, delays that capability by years.

 

 

Timeline varies significantly based on which migration archetype is appropriate for the organization. A Rehost engagement, moving infrastructure without changing code or content structure,  can be completed in four to eight weeks. A Replatform, which is the most common path for enterprise organizations with existing Drupal investment, typically takes three to five months. A Refactor, which involves rewriting custom modules and modernizing architecture, takes five to nine months. A full Greenfield replacement from a non-Drupal platform can take six to twelve months or more. The playbook covers all four paths and the organizational conditions that determine which one is appropriate.
