The website www.ATF.gov recently migrated to Drupal 10, using a progressive migration strategy to move from D7 to D10. The ATF team was able to transition by section, or as they call them, "islands." This approach allowed a single domain, www.atf.gov, to seamlessly serve content from two Drupal websites as one.

In this session, you will learn:
- Goals of the atf.gov migration
- Why a progressive approach was chosen
- The challenges of a progressive migration approach
- Prioritization of the island process
- Tips for taking a progressive migration approach
