Having different navigation in phone and tablet inside same app

I’m a very new in Ionic.

I’m working with a team and we are working in the second phase of a previous app. The first version of the app was just for phones, the second version (we are working now) is oriented to tablets.

The idea is to keep the same app package (.ipa, .apk) for phones and tablets because of the backend and all the logic that already was developed for the first version.

In the design we have two different navigations:

  • Phones: Tabs (already implemented).
  • Tablets: Side menu (hidden until tap).

I want your help to figure out how to solve it.

Is possible have two different navigations in the same Ionic app? Any idea to make this works?
How do you solve this topic in your apps? Maybe you can tell me about your architecture level.
