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, including multi-dimensional tables, REDEFINES, and 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.
The reason a migration runs in weeks and not years is throughput. Renovix serves its COBOL-tuned models on NVIDIA GPUs and pushes millions of transactions through the verifier in parallel.
Domain models trained with NVIDIA NeMo on H100 clusters, using verified COBOL-to-Java pairs from every prior migration.
NVIDIA Triton and TensorRT-LLM serve translation across your whole estate at a rate a CPU stack cannot match.
The shadow verifier replays production traffic across parallel GPU workers, so a single rounding drift is caught before cutover.
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.
