Looking for the alternative

I’m looking for an alternative for this specific part of the import.

import { Nav } from “ionic-angular”; <— This is for ionic 3 and Angular 6

What could be its alternative for ionic 5 and Angular 12?

Many thanks in advance.

This Question indicates that you are not really knowing what you are doing, so i would recommend to follow the Migration Guide: Migration Guide - Ionic Documentation

FYI: In the past, when i had to migrate Apps from v3 to a higher Version, i was best with creating a complete new Project and copy and adjust stuff step by step.
