I'm curious - when rewriting an application from AngularJS to Angular 2+, do you need to be familiar with both, or is knowing just Angular 2+ sufficient?

Understanding the concepts may not be necessary from the start, but having a strong grasp on them will be crucial as you progress. You may need to learn specific techniques that were used to decipher their purpose and functionality, and how to adapt them to the updated framework.
However, not everything will seamlessly transition -- some parts may be straightforward, others may pose challenges, and certain aspects might require complete reimplementation.
It's also important to be mindful of steering clear of outdated methods or ideologies when moving to the new application. Having a solid foundation in your target framework (Angular 2) will play a key role in this process.
When considering whether to rewrite your application, the size and complexity of the project are crucial factors to take into account. In some cases, starting fresh with Angular may be a smoother approach than attempting to refactor the existing codebase.
It's important to note that AngularJS and the current version of Angular (version 13) have significant differences. Prior to diving into either framework, it is advisable to have a solid understanding of JavaScript, and familiarity with TypeScript will be beneficial for working with Angular. For those embarking on a rewriting process, having a grasp of how AngularJS functions is essential - advanced knowledge may not be necessary.
If you're contemplating a phased migration of your application, the NgUpgrade library developed by the Angular team can facilitate the coexistence of AngularJS and Angular components within the same setup.
For guidance on transitioning from AngularJS to Angular, resources like the official Angular guide and wiki offer valuable insights. Additionally, there are third-party companies specializing in assisting with AngularJS upgrades.
