Mainframe & COBOL Modernization
De-risk the mainframe, one capability at a time.
From API-enabling your mainframe to fully migrating COBOL workloads to the cloud, we modernize incrementally with AI-assisted analysis, automated testing and parallel runs.
Why it matters
The skills cliff is real. So is the rewrite risk.
Mainframes still run critical transactions in banking, insurance, government and retail. They are reliable, but the people who understand their COBOL, JCL and CICS are retiring, MIPS costs keep rising, and integrating mainframe data with modern analytics and AI is slow.
The answer is rarely "rewrite everything." We start by making the system understandable, using AI-assisted analysis to document programs, data flows and business rules. Then we choose a per-application path: API enablement, rehosting, automated refactoring or targeted rewrite.
What we deliver
Capabilities
Delivered by senior architects and specialist engineers, with security and governance designed in.
AI-assisted discovery
Program documentation, call graphs, data lineage and business-rule extraction.
API enablement
Expose mainframe transactions and data as secure APIs and events.
Rehost & replatform
Move workloads to cloud or distributed platforms with minimal change.
Automated refactoring
Tool-assisted conversion of COBOL to Java or C# with test-proven equivalence.
Data migration
DB2, IMS and VSAM data migration with full reconciliation.
Parallel run & cutover
Side-by-side validation before any transaction moves.

FAQ
Frequently asked questions
Straight answers to the questions CIOs, CTOs and procurement ask us first.
Should we move off the mainframe entirely?
Not always. Some organizations keep core processing on the mainframe and modernize around it; others exit fully. We model cost, risk and capability for both paths.
Can AI convert COBOL to Java automatically?
AI and specialized tools can accelerate translation significantly, but production-quality conversion still requires architecture decisions, testing and expert review to ensure functional equivalence.
How do you prove the new system behaves the same?
Characterization tests built from production behavior, plus parallel runs comparing outputs transaction by transaction before cutover.
