Enterprise Software Modernisation

Legacy systems, while often mission-critical, can become significant barriers to business agility, innovation, and growth. Patron Technology's enterprise modernisation services help organizations transform outdated systems into modern, cloud-native applications that reduce maintenance costs, improve performance, enhance security, and enable new capabilities. With 24+ years of experience and 500+ successful modernisation projects, we bring proven methodologies and deep technical expertise to safely transform critical business systems without disrupting operations.

Our modernisation practice, based in Mumbai, India, has successfully transformed legacy systems for global clients across banking, healthcare, manufacturing, and government sectors. We've migrated 15-year-old monolithic applications to microservices, transformed COBOL and mainframe systems to modern platforms, re-platformed applications for cloud environments, and rebuilt outdated interfaces with modern UX. Our approach balances business continuity with technical transformation, ensuring zero data loss, minimal downtime, and continuous value delivery throughout the modernisation journey.

Enterprise modernisation is not a one-size-fits-all endeavor. Our comprehensive approach starts with assessment of your existing systems, business requirements, technical debt, and organizational constraints. We then recommend the optimal modernisation strategy – whether rehosting to cloud, re-platforming for cloud optimization, refactoring code, re-architecting for modern patterns, rebuilding from scratch, or replacing with COTS solutions. We execute modernisation in controlled phases, maintaining parallel systems where necessary, conducting extensive testing, and ensuring smooth cutover with comprehensive migration plans.

What sets Patron Technology apart is our holistic approach combining technical excellence with business understanding. We don't just lift-and-shift; we architect for the future, implementing microservices, containerization, API-first design, modern databases, and cloud-native patterns. Clients benefit from India's cost advantages – our modernisation services cost 30-50% less than US/UK firms – while receiving expertise backed by successful transformations including a 15-year banking platform now serving 2M+ users, a healthcare system modernised with zero downtime, and a government system transformed from mainframe to cloud, reducing costs by 60% while improving performance 300%.
