Moving from Create React App to Next.js means rewiring your entire mental model, from client-side routing to server components, and this guide gives you 148 prioritized rules to do it systematically. It covers the critical path first (project setup, routing conversion, data fetching patterns) before diving into fonts and deployment minutiae. The gotchas section alone has 24 rules, which tells you this migration has sharp edges. One thing worth noting: it enforces Next.js 16.x or later and explicitly forbids 14.x or 15.x, so you're working with the latest patterns. If you're staring down a CRA codebase that needs SSR or better performance, this is basically a migration checklist with opinions baked in.
