Designing AngularJS applications by component centric is good practice rather than designing them by controller centric. If you had developed your application following this practice, then it will be easier for you to migrate. Component Directives in AngularJS will have their template, controller, and binding similar to Angular components. But make sure your AngularJS application Component Directives did not use the attributes such as compile, replace, priority, and terminal. If your application implemented Component Directives with these attributes then it is not liaising with Angular architecture. If your AngularJS application was developed using AngularJS 1.5 and the components are implemented using the component API, then you might have noticed the similarities in Angular components.
