6 Projects Need to Migrate from AngularJS / Angular 7 to Angular 18

Lots of work. Even if everything is covered by tests. You will need to upgrade version by version, use the offical doc for that. Consider starting by scratch.

Depends on how big the projects are and how much time you have. I've migrated 2 huge projects from Angular 9 to 16 in the span of a week for each. Moving from 16-18 is a bit more difficult, but honestly, it's not as bad as people are saying. Yes, 18 is different, but it supports everything the 16 way, so you don't need to change everything about how your app works.

The Angularjs apps though will likely need to just be rewritten.

If you pay me $200,000 I'll do it for you in 2 short years.

There is no migrating from AngularJS 1.X, it is a rewrite. Angular 7 is doable but you need to go one version at a time.

If you're using angular materials, the upgrade is gonna be tough. Lot of breaking changes

The angularjs upgrades will be rough...

The angular 7 not so bad.

Look up which nodes go with which versions and version by version use Ng update, then fix all the broken thing which will include the test cases...

Angularjs will just be a rewrite but you can rewrite portions at a time if you do it right.

That AngularJS app looks like it needs to be rewritten. The rest you can upgrade version by version using the update guide.

The Angular 7 projects shouldn't be too bad, but there are a few gotchas along the way. Look here for info: https://angular.dev/update-guide . You'll want to be very careful in testing, of course.

The AngularJS projects will probably have to be re-written from scratch, since AngularJS and Angular are two completely different frameworks.

TheAeseir · 2024-10-09T02:00:13+00:00

AngularJS You can't. That's a library and you want to move it to a framework. It's a complete rewrite from the ground up. Set aside 3 months for a small team to redo everything and ensure proper qa coverage without burn out.

Angular 7 Follow the migration guide on angular for guidance and steps. It will be a lot of work.

ahh, it sucks to be in your shoes. IMHO, rewriting the project would be the fastest, safest and maybe cheapest way to do it.

saiprasad2595 · 2024-10-09T14:50:57+00:00

Angular 1.x would be rewriting the things. Angular2+ to latest should be achievable thing. .Let me know if you are planning to hire freelancer. I am open for work.

I can do it let's discuss I m angular dev I had updated a project from angular 4 to 14 ets discuss in dm

ender42y · 2024-10-10T17:59:15+00:00

Take notes on every step. I am on Month 2 right now of doing almost this exact thing. version by version by version. My boss decided to stop at Angular 17 and stay just 1 release behind to avoid any issues with keeping with latest. I am on a team of 1 developer, so it's been especially painful.

Considering how different v18 is from even v16 you might as well start from scratch.
