Renovix COBOL ingests Enterprise COBOL, JCL, CICS, and DB2 workloads and produces idiomatic Java, Kotlin, or TypeScript — verified against your production traffic before cutover.
Renovix COBOL is built for production estates — not toy examples. We've seen the COPYBOOK with 1,400 lines of nested REDEFINES. We've migrated the program that no one has touched since 1997.
IBM Enterprise COBOL for z/OS through 6.4, including OO-COBOL extensions.
Visual COBOL, Server Enterprise Edition, ACUCOBOL, and Net Express.
Open-source COBOL implementations including embedded EXEC SQL.
BMS maps, EXEC CICS commands, pseudo-conversational state — all handled.
Full JCL parsing, PROC expansion, GDG handling, and SORT/MERGE translation.
EXEC SQL extraction, DCLGEN regeneration, IMS DB/DC segment hierarchies.
Renovix recognizes data structure patterns — multi-dimensional tables, REDEFINES, OCCURS DEPENDING ON — and produces clean, statically-typed equivalents in your target language.
Every output line is annotated with a citation back to the original COBOL source.

Renovix COBOL's verifier replays a window of production traffic against both the legacy program and the generated equivalent. Every diff — including subtle rounding, NULL handling, or sort-order changes — is flagged for SME review before cutover.
The verdict is mathematically grounded, not vibes-based. You sign off on the report, not the engineer.
SCM, JCL, runtime traces, and SME interviews loaded into the workspace.
Call graph, copybook lineage, and business-domain partitioning produced.
Module-by-module generation with target stack, style guide, and tests.
Parallel execution on a traffic slice. Reports for every diff.
Gradual rollout with per-module rollback for the full cutover window.
SOC 2 Type II, OCC heightened standards, FFIEC, NYDFS 500 evidence packs.
NAIC model law alignment, state DOI audit trail exports, actuarial sign-off workflow.
FedRAMP Moderate (in process), CJIS controls, ATO-ready documentation.
"The COBOL we migrated had three living engineers and 38 years of patches. Renovix produced the cleanest specification of that codebase we have ever owned."
We will produce a per-module migration risk report — at no cost — within two weeks.
