Every dialect, every artifact, every edge case.

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.

Dialect

Enterprise COBOL

IBM Enterprise COBOL for z/OS through 6.4, including OO-COBOL extensions.

Dialect

Micro Focus COBOL

Visual COBOL, Server Enterprise Edition, ACUCOBOL, and Net Express.

Dialect

Open / GnuCOBOL

Open-source COBOL implementations including embedded EXEC SQL.

Runtime

CICS transactions

BMS maps, EXEC CICS commands, pseudo-conversational state — all handled.

Runtime

JCL & batch

Full JCL parsing, PROC expansion, GDG handling, and SORT/MERGE translation.

Data

DB2 & IMS

EXEC SQL extraction, DCLGEN regeneration, IMS DB/DC segment hierarchies.

Translation example

From COPY-pasted REDEFINES to typed data classes.

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.

Verifier

Old and new, run in parallel on real traffic.

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.

Workflow

How a COBOL migration runs.

01

Discover

SCM, JCL, runtime traces, and SME interviews loaded into the workspace.

02

Map

Call graph, copybook lineage, and business-domain partitioning produced.

03

Translate

Module-by-module generation with target stack, style guide, and tests.

04

Shadow

Parallel execution on a traffic slice. Reports for every diff.

05

Cut over

Gradual rollout with per-module rollback for the full cutover window.

Integrations

Plugs into your mainframe toolchain.

Source

Endevor, ChangeMan, RTC, Git on z/OS.

Schedulers

Government

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."
