If you're stuck maintaining an AngularJS app and need to modernize it to Angular 2+, this walks you through the three main migration strategies: big bang rewrites, incremental hybrid apps using ngUpgrade, and vertical slice migrations. It covers the practical stuff like downgrading Angular services for use in AngularJS controllers, upgrading old factories to work with new components, converting directives to components with proper Input/Output decorators, and migrating ui-router to Angular's RouterModule. The hybrid approach examples are solid for teams that can't afford downtime. Skip this if your app is already on modern Angular or you're just fixing bugs without touching the framework layer.
