Banking & financial services

For tier-2 banks with COBOL core systems.

Move core banking, payments, and lending workloads off mainframe COBOL without taking the customer-facing system offline. Designed around FFIEC, OCC, and NYDFS 500 expectations.

  • Core banking modulesDemand deposits, savings, term, credit cards, loan origination.
  • Payments railsACH, FedWire, RTP/FedNow, SWIFT — preserve message contracts.
  • Regulatory reportingCall reports, BSA/AML rule engines, OFAC screening.

Reference outcome

A regional commercial bank migrated its 2.4M-line COBOL core banking module to a Kotlin/Spring Boot platform in 11 months. Achieved 100% transactional parity, eliminated $4.2M in annual mainframe MIPS costs, and passed OCC examination on the new stack.

Insurance

For carriers with policy admin built before the web.

Replace legacy policy admin, claims, and rating engines while preserving every actuarial rule. NAIC-aligned audit trail throughout.

  • Policy adminPALS, Genelco, in-house COBOL — all in scope.
  • Claims systemsFNOL workflows, reserves, and reinsurance recovery preserved end-to-end.
  • Rating enginesState-by-state rate filings translated with regulator-friendly traceability.

Reference outcome

A regional P&C carrier replaced its 38-year-old claims engine. Actuarial sign-off achieved on day one of cutover. State DOI audit packages exported directly from Renovix.

Healthcare

For health systems with MUMPS, AS/400, and EDI batch.

Modernize claims processing, EDI 837/835, eligibility, and revenue cycle systems — without touching PHI any more than necessary.

  • EDI X12837, 835, 270/271, 276/277 mapped to FHIR or modern internal contracts.
  • HL7 v2 → FHIRBidirectional translation during cutover so partners aren't forced to change.
  • HIPAA-safe pipelinePHI redaction at ingest; BAA-compliant deployment options.

Reference outcome

A non-profit health system retired its IBM i revenue cycle. ROI inside 14 months, primarily from eliminated outsourced AR work.

Government

For agencies under modernization mandates.

Federal, state, and local agencies operate the largest COBOL estates on earth. Renovix is FedRAMP-track and built for ATO timelines that don't slip.

  • FedRAMP trackModerate baseline in process. SSP and POA&M support included.
  • Air-gapped optionOn-prem and GovCloud deployment for classified workloads.
  • Procurement-readyGSA schedule, OTA-friendly, sole-source justification packages.

Reference outcome

A federal benefits agency reduced its modernization timeline from 7 years to 18 months on a flagship subsystem, with continuous IV&V review.

Manufacturing

For factories with RPG, COBOL, and custom ERPs.

Modernize MES, custom ERP, and shop-floor systems written on AS/400 or .NET Framework — without disrupting the line.

  • MES & shop floorReal-time control loops preserved. OT/IT boundary kept clean.
  • ERP modernizationHome-grown ERP modules unbundled into composable services.
  • EDI to partnersTier-1 OEM integrations (EDI, AS/2) preserved through cutover.

Reference outcome

A precision parts manufacturer modernized its 1.8M-line RPG ERP in nine months. Zero scheduled downtime on the line.

By workload

Common modernization journeys.

Core banking platform

COBOL + DB2 + CICS → Kotlin/Spring Boot + Postgres + Kafka, with payments rails preserved.

Policy admin

Mainframe COBOL or PALS → modern policy lifecycle on EKS, with actuarial traceability.

Claims platform

Legacy claims engine → event-sourced platform with audit-friendly state transitions.

Revenue cycle

IBM i + custom RPG → modular billing and AR pipeline with EDI continuity.

Public benefits

State eligibility systems → modular workflow platform with appeal trails.

Custom ERP

Home-grown RPG ERP → composable services that leave Tier-1 EDI untouched.

FAQ

Common solution questions.

Yes. The most common starting engagement is a single subsystem of 100k–500k lines. We expand from there once the model is proven on your code.
Renovix works alongside them. Many of our deployments are co-sold with Accenture, Deloitte, and Capgemini — they own change management, we own the engine.
No. Renovix offers VPC and on-prem deployments. For air-gapped environments we ship a hardened single-tenant appliance.
Java 21, Kotlin, TypeScript, C# (.NET 8), Go, Python. Output matches your platform team's existing conventions.

"Renovix is the only vendor we've worked with that signed a fixed-price deal on legacy modernization — and met it."
