Migrating from the Next.js Pages Router to the App Router requires restructuring file conventions to use Server Components, updating data fetching logic, and defining new server-client boundaries for scalable architecture.

Next.js Server Components fetch data directly on the server and stream content to the client using partial prerendering and parallel routes, improving initial load performance without manual loading states.

Structuring routing and server-client boundaries in Next.js 14 involves leveraging App Router file conventions, isolating Client Components, and using Server Actions to maintain progressive enhancement and optimal data flow.

Yes, parallel routes and route handlers enable advanced data fetching in Next.js by allowing simultaneous rendering of multiple route segments and exposing API endpoints for complex full-stack React data flows.

Manage cache strategies and SEO metadata in a Next.js App Router project by utilizing built-in caching mechanisms for data fetching and exporting dynamic metadata objects from layout and page files.

Use Server Actions instead of API routes in Next.js when handling form mutations and progressive enhancement directly within Server Components, reducing client-side JavaScript and simplifying server-client data mutations.
