Next.js - Migrate from Pages to App Router

A few months ago, Next.js introduced App Router, a new way to build React applications using the latest features like React Server components and streaming. This was included in Next.js version 13 and is meant to replace the Pages Router eventually. I have been using the App Router for all my builder projects for a while now. In fact, I usually kicked off projects with the standard create-next-app script that starts a new app from scratch.
