Angular version upgrade from 8 to 17 lts version

#angular #javascript #webdev #frontend

Hello Readers,

I'm working on big application with around 18 angular modules. Involving Microarchitechture framework as well.
Our angular project is currently build on Angular 8.

Issue:
Client requires a VAPT report and for that we need to migrate our Angular 8 and Angular 12 project to Angular 17 lts version.
My team is able to upgrade version for some of the modules to Angular 12. For some we are unable to do it.
Since, some of our modules are also using external 3rd party libraries, some of which have removed support after angular 12.

Inputs from anyone on how to approach or any tools which can help in doing it in less time will be highly appreciated.
