What is the recommended strategy for migrating large AngularJS apps?

The Incremental (Hybrid) approach is best for large apps, as it allows running AngularJS and Angular side-by-side using ngUpgrade for feature-by-feature migration without a full stop in development.

Can I use modern Angular services in my legacy AngularJS code?

Yes, by using the downgradeInjectable function from @angular/upgrade/static, you can make modern Angular services available to your legacy AngularJS controllers and services.

How do I handle routing during a framework migration?

This skill provides patterns for migrating from $routeProvider to the Angular Router, including strategies for managing routes in a hybrid environment where both frameworks coexist.

Should I migrate services or UI components first?

It is generally best practice to start with services and utility functions. They are typically easier to migrate and can be provided to both frameworks, creating a solid foundation for component migration.
