To migrate to the Next.js App Router, you need to map your existing pages to the new app directory structure, update data fetching methods to use Server Components, and replace getServerSideProps with Server Actions. This transition provides better rendering strategies and nested layouts.

Structuring routing in the Next.js App Router involves using the app directory to define nested routes and layouts, leveraging Server Components by default to optimize rendering. Define route segments with folders and use layout files to share UI across multiple routes.

Next.js Server Components handle data fetching by executing directly on the server, allowing direct database access. Server Actions enable you to mutate data and handle form submissions without creating separate API endpoints.

Yes, the Next.js App Router supports middleware, allowing you to run code before a request completes. This is ideal for multi-tenant applications to handle authentication, rewrite redirects, and dynamic routing based on user context.

Yes, you can implement Next.js caching strategies like fetch caching and use Vercel for deployment. Vercel natively supports App Router features, optimizing Server Components and middleware execution for fast global distribution.
