Migrating to Next.js App Router with zero downtime

The blog post discusses a migration strategy to adopt Next.js App Router incrementally without disrupting ongoing work. It outlines steps such as upgrading Next.js, migrating routing hooks, creating a temporary /app/new directory, importing existing code from /pages, using a query param to access the App Router, and removing the /pages directory. The post also highlights the benefits of React Server Components when applied in load-bearing code paths.
