Can you handle our mainframe data formats?

Yes. We read EBCDIC-encoded data, packed decimal fields, COMP-3 formats, and VSAM files, converting to modern UTF-8 and standard data types.

Do you do automated COBOL-to-Java conversion?

We avoid automated 1:1 transpilation as it produces unmaintainable code. Instead, we redesign for modern patterns while preserving the exact business logic.

How do you handle batch processing replacement?

We convert batch COBOL jobs to scheduled cloud functions or event-driven pipelines, maintaining the same processing windows and data integrity guarantees.

Migrate from COBOL to Modern Cloud Applications

Replace aging COBOL systems with modern, maintainable applications before the last COBOL developers retire.

Migration: COBOL to Modern

From COBOL to Modern Cloud Application

Why Migrate

Talent Crisis: The average COBOL developer is over 55. Finding replacements is increasingly difficult and expensive.
Mainframe Costs: Mainframe licensing, hardware, and specialized staff cost millions annually. Cloud infrastructure costs a fraction.
Business Agility: COBOL systems take months to modify. Modern applications deploy changes in hours with CI/CD pipelines.

Migration Roadmap

COBOL System Analysis (3–4 weeks): Catalog all COBOL programs, copybooks, JCL jobs, and data structures. Map business processes and dependencies.
- Program inventory
- Business process maps
- Data dictionary
- Migration strategy document
Modular Rebuild (8–16 weeks): Rebuild COBOL functionality as modern microservices, migrating batch jobs to scheduled cloud functions.
- Modern application services
- Batch job replacements
- API layer
Data Migration & Parallel Run (3–4 weeks): Migrate mainframe data, run both systems in parallel for validation, and execute the cutover.
- Migrated database
- Parallel run validation
- Production cutover

Risks & Mitigation

Decades of undocumented business rules in COBOL code: We use static analysis tools to trace COBOL program flow and validate with domain experts through structured interviews and test scenarios.
Batch processing timing and sequencing dependencies: We map all JCL job schedules and dependencies, recreating them as orchestrated workflows with the same ordering guarantees.

Estimated Scope

Hours: 400–800 | Cost: $800–$1,600 | Timeline: 14–24 weeks
