What is the best strategy for migrating a large AngularJS app?

The incremental hybrid approach using ngUpgrade is recommended for large applications, as it allows you to run both frameworks side-by-side while migrating feature by feature without a full stop in delivery.

Does it support routing migration?

Yes, it includes guidance on moving from legacy ngRoute or UI-Router systems to the modern Angular Router while maintaining navigation consistency.

Can this skill help with service migration?

Yes, it provides specific patterns for converting AngularJS factories and services into Angular Injectables and bridging them across frameworks using dependency injection.

How do I handle dependency injection during a hybrid migration?

The skill demonstrates how to use downgradeInjectable to make Angular services available to AngularJS and InjectionTokens to make legacy services available to the new Angular code.
