Ionic Angular Migration to 5.0.0

With 5.0 released recently, upgrading a project to the latest version of Ionic is as simple as updating a few dependencies. Check out how to update an Ionic Angular project.

Thanks so much for the video, I had a lot of trouble upgrading to Angular 9 where I couldn't get my app to compile as I did the package change manually. However your instructions 4:32 worked. I highly recommend posting this instruction in the changelog or in the ionic readme as this is critical information and can save many hrs of headache. Thanks again!

Thanks for the Video. This Video is specific to upgrading ionic 4 to Ionic 5. My question is what are the steps in order to upgrade Ionic 2/3 app to Ionic 5 ?

Interesting overview. For my simple prototype app that I had made last year (just a demo that let me reorder a list) I tried to update but almost immediately came off the rails.



So I tried to upgrade to Angular 8 first with `npm i @angular/core@"~8.x.x"` but that failed as it needed `npm i zone.js@~0.9.1`.

Initially I posted my full solution here in the comments but it was a bit of a mess so I've moved it over to StackOverflow:
