Angular 2 to 4/5/6: What are some things to know/do/check before upgrading?

I have to convert an Angular 2 project to Angular 6. It has its backend made with WebAPI which is connected to SQL Server. I think it is based on the MVC.

Also, I have to make the application modular i.e. I have to combine all the components that are dependent on each other: make a module for them and then import that module in app.module.

So what are some things that I should know/do/check before upgrading to Angular 2 to 6?

And how will I check which component is dependent on some other component because the app has 250+ components?

Updating:

There is so much going on between these versions, I recommend slowly moving forward along each of the major versions (2->4->5->6).

You should check out https://update.angular.io/, that site will tell you what to look out for for each of these version jumps.

Modularity:

Concerning modularity: ngModules was introduces before the final version of Angular (2), you can probably consider upgrading and ngModule consolidation two distinct projects.

Dependency checks:

You could use a tool like https://github.com/compodoc/ngd to visualize your dependency graph.
