To migrate a Next.js 15 app to Next.js 16, handle breaking changes by adopting async params and searchParams, enabling Turbopack defaults, and configuring cacheComponents. This ensures your upgraded project follows official patterns and avoids runtime errors.

The Next.js 16 proxy.ts file replaces middleware.ts to handle request interception and routing logic. Implementing proxy.ts follows updated Next.js 16 best practices, ensuring proper App Router patterns and project structure configuration.

Parallel routes and dynamic routes in the Next.js App Router are implemented using specific folder conventions for rendering multiple UI segments simultaneously. Following Next.js 16 patterns ensures correct route handler usage and updated project structure.

Next.js 16 uses Turbopack defaults to maximize build performance, and cacheComponents must be explicitly configured in your next.config file. Applying these updated Next.js configurations ensures optimal rendering and caching behaviors.

Updated image usage patterns in Next.js 16 require adjusting image component imports and configurations to align with new caching and rendering behaviors. Implementing these patterns correctly avoids breaking changes during migration.
