How OpenLegacy AtomIQ Powers Process-by-Process Modernization

Every modernization program eventually hits the same wall: nobody knows exactly what the mainframe does anymore. Decades of COBOL, CICS transactions, JCL jobs, BMS maps, and copybooks have fused into a system that runs the business but resists explanation. The original architects have retired. Documentation, if it exists, is outdated. And yet leadership wants a migration plan with timelines, costs, and risk estimates by next quarter.

The Data Your Business Runs On Is Harder to Reach Than It Should Be

Enterprises running IBM mainframes aren’t doing so by accident. These systems process millions of transactions every day across vital enterprises like banking, insurance, healthcare, and government.

The Legacy Data Problem Nobody Talks About

Every enterprise sitting on a mainframe has a hidden productivity drain: getting to the data. Analysts wait for DBA tickets. Developers reverse-engineer schemas from decades-old documentation. Integration teams stitch together SSH tunnels, emulators, and desktop SQL clients just to run a simple query against DB2 on z/OS.

The average global enterprise wastes more than $370 million annually due to being unable to efficiently modernize outdated legacy systems. Mainframe modernization projects, meanwhile, delivered between 288% and 362% ROI in 2025, according to a major survey.

OpenLegacy vs Broadcom: Which Fits Enterprise Modernization?

leigh-ann.s@openlegacy.com (Leigh-Ann Silver) — Tue, 30 Sep 2025 05:54:07 GMT

OpenLegacy vs Broadcom is a comparison some enterprises make when modernization becomes urgent but disruption is not an option. Broadcom provides a broad enterprise software portfolio including governance, security, automation, and mainframe tooling that helps run and secure the estate you have. OpenLegacy focuses specifically on phased, risk‑managed legacy‑to‑cloud transformation.

What Is Platform as a Service (PaaS)? [Types, Benefits & Examples]

For enterprises with mainframe or IBM i, PaaS accelerates app delivery—but legacy modernization succeeds when you change one boundary at a time: decouple → coexist → migrate. That approach reduces risk and keeps mission-critical channels online.
