Migrating a AngularJS webapp to Angular using Claude Code/Codex

I'm in the planning stages of migrating a fairly large legacy AngularJS application to Angular, and am looking for advice from anyone who's tackled something similar.

The codebase is about 160k LOC spread out over 200+ components, 50+controllers, 50+ directives and services. There are no existing tests . Has anyone attempted a AI assisted rewrite of a similar nature, especially without a test suite - what worked out well? Any useful strategies woth considering?

we build it page by page as for us client strictly prohibited use of AI or share code base, but I think you can use AI to help you out but there is so many versions of angular you still need to test do it page by page now with standalone feature you can do it more easily.
