Large-Scale Divi to Gutenberg Migration for 290 Healthcare Sites
Executive Summary
The project involved modernizing a network of 290 WordPress sites across the East and West US regions, all originally built using the Divi theme. To establish a future-ready foundation, the platform was transitioned to a Full Site Editing (FSE) architecture with Gutenberg-based blocks, enabling improved performance, consistency, and editorial control.
Data migration was executed efficiently using the core WordPress REST API combined with HTML scraping, ensuring content integrity while minimizing disruption across the network.
