Migrating from Ionic 1 to Ionic 2


We have been using Ionic 1.x for the past year and we had very good results with it. We are in the last version of V1 with Angular 1.5.3 Now that Angular 2 is released we were thinking to upgrade to Angular 2 and Ionic v2. Our App is quite big so we need to do this migration gradually.

I’ve been reading a bit about migration from Angular 1.x to Angular 2 and there seem to be a process to gradually be doing that. Is it possible to do a smooth transition with ionic as well? As I see some tags are the same in Ionic 1 and Ionic 2. As well regarding Css there might be some collisions right?

What should be the best process to gradually integrate Ionic 2 into our project? Unfortunately the App is quite big and it can’t be done all at once.

It will be super helpful if there was a kind of guideline to point devs into the right direction.

many thanks,


I think there’s no way to upgrade from 1 to 2.
Version 2 is totally different from 1, mainly because it use’s Angular 2. You’ll have to rewrite it.

I was thinking on a gradual migration. Angular 2 can run Angular 1
