without huge modifying in codebase

This is not going to be possible.

Ionic 1 to 2/3 is a large jump from AngularJS to Angular2, which requires a switch to typescript and other fundamental framework alterations.

Here is a good post about AngularJS vs Angular2

Here is a good write up for the migration from Ionic 1 to Ionic 2 that should help.

Then once that's done, the migration from 2 to 3 is not that big of a leap.
