While working on ippocra.com, I’ve found myself in a bit of a predicament when I was trying to update angular (which they release a new version every 6 months, so it’s kind of something you’ve got to do).
I’ve figured out that the classic command that is written everywhere it may works for folks that have a set of dependencies that are pretty standard:

ng update @angular/core@20 @angular/cli@20

That will update form angular 19 to 20. Which is fine. But it may breaqk if you use other dependencies like ngrx .

So here is the thing to update also these in one go:

ng update @angular/core@20 @angular/cli@20 @ngrx/store@latest

That will update everything you need in one go.

If you have a problem with a dependencies, you need to pass it to that command.

Hope it helps.
