Department of Transportation is a huge Drupal multisite installation that needed support with their Dev Ops and deployments. Most of the work was on the backend with various agencies in DOT.
Their cloud provider forced the DOT Drupal multisite installation to update their PHP version fron 5 to 7. Unfortunately its not as simple as updating your personal computer's operating system. There were a ton of dependencies that all needed to be accounted for.
Created a comprehensive test plan for over a 100 modules and custom code on the main DOT Drupal installation. When compatibility issues arose, we developed patches for those specific modules. The migration was ultimately successful and helped prepare for the Drupal 8 migration.
We also managed weekly deployments and contributed improvements to build scripts and integrations with their cloud provider. Also contributed code to their main theme implementation.
