Can I automate porting Angular 1 code to Angular 2 ?

No, currently there is not any such tool available that ports the Angular 1 code to the Angular 2 code.

In the process of porting, the Angular 1 code to Angular 2, the side by side manual conversion of Angular 1 directives to the Angular 2 components takes place because they are two different frameworks and hence requires different approaches to solve the same problem.
