Organizations on GCOS aren't just stuck on old hardware — they're starving for functionality the platform can't deliver. GCOSHelp doesn't just migrate your COBOL. We study your operations, find the gaps and shadow IT your team built to compensate, and redevelop the application to fit your organization today.
We don't just convert code line-by-line. We learn how your organization actually works, identify what the legacy system can't do, and deliver an application that covers both.
We inventory every COBOL program, EC script, database file, and VISION screen form. But we also study your operations — the workarounds, the spreadsheets, the shadow IT your team built because the GCOS system couldn't keep up.
AI-assisted redevelopment of your application on the platform and language of your choice. We preserve all working functionality while closing the gaps your organization has been living with for years.
Rigorous validation of both migrated functionality and new capabilities. Unit testing with your subject-matter experts, full UAT, and a managed go-live with post-implementation warranty.
Yes, the platform is unsupportable. But the real cost is years of frozen functionality — and the shadow IT your team built to compensate.
No one modifies GCOS applications anymore. So your team built workarounds — spreadsheets, Access databases, manual processes — to fill the gaps. A straight code conversion just preserves those gaps. We eliminate them.
DSS database structures, file organizations, and data types have no direct SQL equivalent. We map every record type, column, and relationship to your target DBMS — SQL Server, Postgres, Oracle, MariaDB, or DB2 — with validated data conversion.
GCOS EC scripts control scheduling, file handling, batch sequencing, and error recovery. We extract that operational logic and re-implement it in modern orchestration tools on your target platform.
VISION screen forms and TPS/6 transaction processing can't be lifted-and-shifted. We re-architect every screen interaction for web, desktop, or API on your target platform while preserving the underlying workflow.
A line-by-line conversion gives you the same limitations on a newer platform. We deliver an application that works the way your organization actually needs it to.
Before writing a line of code, we interview stakeholders, map workflows, and catalog the shadow IT your team built around the GCOS system. The result is an application scoped to your organization — not just a copy of what you had.
We use AI-assisted code analysis and generation to accelerate redevelopment, but every functional decision is made by engineers who understand both the source platform and your operational needs.
We start with a thorough evaluation — cataloging every asset, scoring complexity, and identifying enhancement opportunities — before quoting the engagement. GCOSHelp is a focused brand of Greymine, backed by a broader legacy modernization practice.
The hardware is gone. The emulator is unsupported. And your organization has been working around the system's limitations for years. Tell us about your environment and we'll show you what's possible.
