VerraDyne is a world leader in legacy application migration and modernization. For more than two decades we have converted mainframe and midrange systems — IBM Mainframe, IBM AS400 / iSeries, HP3000 / MPE, OpenVMS, Unisys ClearPath / MCP, Honeywell Bull, Wang VS, CA Ideal and COBOL — into clean, native, maintainable code on Windows, UNIX, Linux and the cloud.
We don’t emulate legacy systems — we convert them. Every program, screen, data file, batch job and interface is transformed into modern code your team can own, and our AI-powered toolset LexAI makes the whole migration faster, safer and more predictable.
Choose your platform. Each service converts the complete application ecosystem — code, screens, data and batch — not just the programs.
COBOL, CICS, IMS, DB2, JCL and security converted to native open systems.
COBOL, RPG, CL, DDS screens and DB2 data modernized to .NET.
COBOL, BASIC, VPLUS, KSAM / IMAGE and MPE JCL to Windows or UNIX.
COBOL, Fortran, FMS / DEC FORMS, RMS, DBMS / RDBMS and DCL converted.
COBOL, ALGOL, TIP / COMS screens and ECL / WFL batch modernized.
COBOL, GCOS screens, IDS / VSAM data and JCL to open systems.
Wang COBOL, VS screens, ISAM files, procedures and USERSUBS converted.
CA Ideal / Datacom panels, programs and data files to COBOL, VB.NET or C#.
Any COBOL dialect to Micro Focus, Fujitsu .NET, VB.NET or C#.
Complete conversion to modern C# on .NET with data migration and testing.
AI-driven analysis, business-rule extraction and automated code conversion.
Your applications run natively on modern platforms in industry-standard languages and databases. No runtime, no lock-in, no legacy layer left behind.
LexAI maps dependencies, extracts business rules and automates conversion, compressing months of discovery and rewriting into weeks.
Over one million lines of COBOL converted to C# on .NET for a state educational organization serving more than 150 school districts.
VerraDyne has a reputation for delivering migration projects on schedule and at a fixed rate, with predictable outcomes.
Programs, screens, data, batch jobs, interfaces and security all move together, so nothing is left on the old platform.
Teams in the United States, Canada and Australia serving finance, healthcare, retail, manufacturing and city, county, state and federal government.
