The document discusses how testing helped with migrating to API version 0.6 of OpenStreetMap. It notes some of the key changes in the migration like moving the backend database from MySQL to Postgres and adding foreign keys. It then explains that testing on a development server called "cruise" helped uncover problems with the migration, like invalid translation files and issues with applications that needed to be fixed before full deployment. The document emphasizes that thorough testing was important for the successful migration to the new API version.
