Overview
Mainframe & Legacy Modernization
Studio 402 transforms brittle legacy systems into durable, cloud-native software infrastructure. We help you migrate mainframes, refactor aging codebases, and eliminate technical debt.

Maintaining legacy infrastructure often creates a bottleneck for innovation and growth. Our approach to custom software development ensures that your modernization journey results in a production-ready system that supports real-world scale.
Strategic Transformation for Critical Systems
Mainframe transformation is not just about moving code; it is about preserving business logic while unlocking the flexibility of modern environments. We audit, stabilize, and rebuild systems that have outgrown their original architecture.
- Mainframe to cloud migration and re-platforming
- Legacy code refactoring and production hardening
- API-first integration for isolated legacy silos
- Database modernization and data integrity preservation
- Security audits for aging application stacks

From monolithic bottlenecks to modular agility.
Why Modernize Your Legacy Infrastructure?
Info.
// The Cost of Inaction
We specialize in rescuing projects that have hit a ceiling, whether they are decades-old mainframes or more recent prototypes that lack the security and maintainability required for today's compliance standards.
