In this chapter, we are going to take a look at migrating an existing Ionic 1 app to Ionic 2/Ionic 3. We are first going to build a simple Todo app using Ionic 1 and then understand how we would go about migrating the same to Ionic 2:
- Why migration?
- Building a simple Ionic 1 Todo app
- Migration game plan
- Migrating the Ionic 1 Todo app to Ionic 2
This migration guide will still be valid if you would like to migrate from Ionic 1 to Ionic 3 as well. Refer to Chapter 11, Ionic 3 to better understand the changes in Ionic 3.
