Migrating from Next.js Pages Router to App Router requires updating file conventions to the new directory structure, adapting routing strategies, and applying middleware or proxy patterns to ensure performance optimizations and maintainable architecture.

Fetching data in Next.js Server Components is best handled by executing requests directly on the server within the component, leveraging modern rendering strategies and caching mechanisms to optimize performance without sending client-side JavaScript.

Generating metadata for Next.js App Router routes involves exporting a metadata object or generateMetadata function from your route files, allowing you to dynamically configure titles, descriptions, and other meta tags for robust SEO.

Use Next.js Route Handlers for standard HTTP request processing and building explicit API endpoints, whereas Server Actions are better suited for mutations and form submissions that interact directly with the Server Components architecture.

Deploying a Next.js App Router project outside of Vercel is fully supported, though you must adjust deployment considerations and environment configurations to ensure the server components and middleware function correctly on your chosen hosting platform.

Next.js Server Components may fail to cache data as expected if the caching strategies are misconfigured, requiring you to audit your fetch requests, route segment configurations, and middleware behavior to ensure proper data retention.
