COBOL, read once. Java, generated under guardrails.
Business rules recovered from COBOL paragraphs, sections and copybooks, then rebuilt as tested Java and Spring services, with the original logic traced rather than guessed.
- Weeks to hoursTo deploy, after the refactor to Java
- 75%Lower token spend, with persistent context
- 100%Of work orders traceable end to end
- ZeroMainframe licensing in the target state
Sources needed
Four ways COBOL conversions stall.
Dialect ambiguity
EBCDIC, COMP-3 and VSAM details get assumed instead of detected, and the assumptions are wrong.
Dialect detection
Trapped business logic
Decades of rules live only in the COBOL, and the people who wrote them have left.
Living Specs
Unstructured batch flow
JCL job chains and paragraph-level control flow resist a clean rewrite by hand.
Deterministic mapping
No test coverage
Legacy paths that have never been tested get converted with no way to check the behavior matches.
Traceability
COBOL to Java, in four passes.
Ingest and map
COBOL, JCL and copybooks parsed to paragraphs, sections and a real call graph.
Specify business rules
Rules recovered from the code become Living Specs, confirmed by your SMEs.
Convert
Deterministic tiers run first, and AI handles the residual, routed by complexity.
Review and ship
Council review, then an engineer's approval, then a gated deploy with the record intact.
Same foundation.
The same platform converts Sybase, IDMS and CODASYL, and RPG portfolios.
Other modernization paths
Pick one COBOL application. We'll show you the specs it has been hiding.
We map the dependencies and business rules, scope wave one, and hand back the specs.
