I am trying to migrate my angularjs(1.6) to angular 5. As of now I am focusing over migration of one page and want to go for both frameworks angular js and angular 5 running in same application.

I have gone through various links and found some approaches like going for incremental migration i.e. from angular js to angular 2 then angular 4 later angular 5 ; Modifying the scope syntaxes etc

My query is that should I modify the above scope related syntaxes in my current angular js application or I should create a new angular 2 /5 project and then move my js application code to newly created angular 2/5 app.My application is huge one. Also, I want to use ngUpgrade. Not sure where to use. Pls verify the approach and help in this migration

  • This link might help you. But I think you should create a completely new project to be able to edit and upgrade later, that's a good solution Commented May 2, 2018 at 9:44

'create a new angular 2 /5 project and then move your js application code to newly created angular 2/5 app' is better in my opinion

there are some huge architecture differences between Angularjs and angular2+.

angular.js is a classic MV* architecture framework, you may write code in controllers, services, splitting these files into different folders like a MVC structure.

while angular2+ is a component based framework.you can write app in component based pattern.just like react or vue .although you still can write it as a MVC structure.but remember why you want to refactor your project.

But my application is a huge one.It will take time to rewrite the entire code.Cant I go live using angular-hybrid approach?
we also had a huge Angularjs project and we refractored it to a react version.what we tried to do was when we got new requirements ,we developed on the new one and moved the old project's funcs to the new project gradually.
did u rewrite the entire code again i.e. old project's functions to the new application? manually using angular 2/react syntaxes?
yeah, we did, it's not that difficult.all you need is some time actually . so why you want to refactor your project? think Angularjs is slow or just wanna use new framework.
yes, we want to use new features of angular 5 and angular js is bit slow.Any idea over the medium.com/contentsquare-engineering-blog/…
