Summary.

The University of San Francisco (USF) intranet was having issues with usability, performance, extensibility, and maintainability. This can often be the case when you maintain a complex and big site built on Drupal 7 Open Atrium over an extended period of time. USF needed to take a step back and plan for the next iteration of their intranet so they called Tandem.

Challenge 1: Complex Migration

One of the biggest challenges identified was migrating the existing Drupal 7 Organic Groups setup to utilize Drupal 8 Groups. Previously, there was no migration path that existed for this, however, now there is. 😃

Tech:

• Drupal 8
• Groups Module
• Custom Modules

Entities Migrated:

250K

Challenge 2: Custom Functionality

On top of the Organic Group to Group migration, there was numerous other internal functionality that needed to rebuilt. Some of this included, but not limited to:

• Custom user weighted draggable tables
• Integration and functionality with two internal APIs
• Custom CAS integration with the Group module.

Challenge 3: Performance

Tandem also went through rigorous performance testing and tweaking of the custom functionality via New Relic, Blazemeter and Blackfire.
