Migrating from Cordova to Capacitor

So i’ve started following the guide here: https://capacitor.ionicframework.com/docs/cordova/migrating-from-cordova-to-capacitor/

I’m still using ionic v3 for now until i’m able to migrate the codebase, but I want to start fully using capacitor ahead of migrating as I like the idea of being able to check in the platforms source code.

So out of the 3 links, what am I supposed to use? Do I abandon all non capacitor plugins & imports and only use the instructions outlined in the capacitor docs? Or do I use some sort of a hybrid?
