From mainframe to cloud, without stopping the operation
We modernize legacy COBOL and mainframe systems incrementally: business rules preserved, cost and risk under control, and the public service always online.

one incremental, safe migration: from COBOL/mainframe to modern architecture, without stopping the operation
The legacy runs the service — and traps the operation
The COBOL/mainframe system still works, but every year of maintenance gets more expensive, riskier, and more dependent on a handful of people. The gaps we see most:
Critical system locked to the mainframe
The service that runs the operation lives in COBOL on a mainframe. Every update is risky, every outage hits the public, and the hardware gets harder to sustain each year.
Maintenance cost that only grows
Licenses, support contracts, and running the legacy consume a rising share of the budget — money that could fund new services instead of just keeping the lights on.
Few people understand the legacy
Knowledge of the system sits with a small group, many near retirement. When they leave, the memory of how the business rules actually work leaves with them.
Fear of migrating and halting the operation
The fear of a blackout stalls any modernization. The system is too essential to switch off, and a big-bang cutover is a risk no agency wants to take.
Off the legacy, in safe steps
We modernize with the method we learned shipping critical and management systems for the public sector in production — no blackout, with the business rules intact.
Mapping the business rules
Before migrating, we understand what the legacy really does: we read the COBOL, recover the undocumented rules, and turn that knowledge into a living specification — the same way we structured a management system for the public sector, with well-defined processes and compliance.
Incremental migration (strangler)
Instead of a risky cutover, we replace the legacy in parts: each new module responds in place of the old one, with no blackout. The system stays online as it migrates, module by module.
Cloud and new architecture
We rebuild the modules on a modern architecture, with process automation and integration — the way we digitized intake, procurement, and contract management in a management system for public agencies. Scalable infrastructure, with no dependence on proprietary hardware.
Validation and continuity
Every migrated module is validated against the legacy to guarantee the same result, with rollback available at each step. The operation never stops, and regulatory compliance is preserved from start to finish.
