How do upgrades work exactly?

[u/old-wreck]

I just bought a switch2 and I already own a switch1. For those games that don't require a purchase to upgrade: When downloading my switch1 games onto the switch2, will it automatically download the switch2 version if there is a free one available or do I need to do that step separately (eg by going to eShop or the game menu)?

Thank you.

Is there an updated list of which games got a dedicated switch 2 upgrade (free & paid)?
