Replacing React Router with Next.js file-based routing involves adopting the app router to structure routes and layouts, guided by comprehensive migration checkpoints that validate routing modernization and data fetching patterns.

Adopting Server Components when moving from CRA enables zero-JS hydration and improved performance by migrating data fetching patterns to Next.js Server Components and Server Actions.

Handling image optimization when migrating from CRA to Next.js requires aligning existing asset handling with the Next.js image system, applying specific guidance and validation checks to ensure proper optimization.

Yes, you can use Next.js Server Actions to replace CRA data fetching by migrating existing data retrieval patterns to Next.js Server Components and Server Actions with enforced validation and safety checks.

Migration limitations include ensuring all React Router structures correctly map to Next.js app-router file-based routes and layouts, requiring careful validation and safety checks to prevent data fetching and asset handling conflicts.
