Enterprise software modernization in Maharashtra often faces legacy database schemas locked inside on-premise Windows servers. Rewriting everything at once risks operational chaos.

At InfynoSpark, we use the Strangler Fig migration pattern. We deploy a Next.js 15 web application layer in front of the existing system, isolating legacy SQL tables behind RESTful microservices.

By utilizing Server Actions and React Server Components (RSC), we reduced administrative dashboard payload sizes by 64% while enabling real-time inventory tracking for manufacturing units across PCMC and Chakan industrial corridors.
