React Website Server Migration

I need to move my live React-based website from its current host to a new server and want the transition to be completely seamless for users. The job covers copying the full codebase or production build, recreating environment variables, configuring Node.js and a web server such as Nginx or Apache on the destination machine, migrating SSL, pointing DNS to the new IP, and confirming that every page, route, and API call works exactly as before.

Deliverables
• Site running flawlessly on the new server, accessible over HTTPS
• Step-by-step documentation of the migration and any configuration changes
• Quick rollback or recovery plan in case we need to revert

I will open a low-traffic window for the switchover so downtime stays near zero. Let me know what access or preliminary details you need and your estimated timeline, and we can get started right away.
