Migrating an existing Ionic 2 app to Ionic 4.0

Hello, I have an existing Ionic 2 app and have decided that it’s time to migrate it to Ionic 4. I have looked around and found various guides for migrating to 4, however most of them are either from Ionic 1 or Ionic 3. My question is would a Ionic 3 to 4 guide work well for me, or should I take a different approach to migrating?

The jump from Ionic 2 to 3 wasn’t very big, therefore a 3 to 4 upgrade guide should work for 2 to 4 as well.
