Legacy Modernization
COBOL isn't dead — it's mission-critical. We modernize what needs modernizing and stabilize what needs to keep running, without betting your operations on a full rewrite.
The Problem
Your retirement platform runs on COBOL, mainframe batch jobs, and OmniScripts written 20 years ago by people who no longer work here. You can't hire replacements. You can't afford a full rewrite. But the systems have to keep running.
How We Help
We bridge legacy and modern — 21+ million lines of COBOL code migrated, documented, and supported. Over 300 COBOL applications migrated to Java on mainframe and distributed platforms. 250 retirement applications migrated to AWS and Azure. We've managed 12 successful OMNI upgrades and implementations, performed assessments and rewrites of thousands of legacy OmniScripts, and built tools that parse 35,000+ custom scripts. We help clients develop 3-4 year decommissioning roadmaps while keeping production systems stable.

The Translation Gap
Why Most Retirement Technology Modernization Fails — And What the Winners Do Differently
The future of retirement technology will not be won by the firms with the most tools, the biggest teams, or the loudest AI announcements. It will be won by the firms that can translate domain knowledge into technical execution faster than their competitors.
Mid-market Recordkeeper — Stabilizing a Platform in Crisis
A mid-market recordkeeper had retirement systems running without standardized production environments and no dedicated ops staff. Convergent deployed 5 senior consultants to stabilize operations, establish change management, and build a Relius decommissioning roadmap.
Legacy Is Not a Failure State
The recordkeeping platforms that run American retirement aren't broken. They're old, complex, and politically inconvenient — but they work. Treating them as problems to be erased usually creates the problem you set out to avoid.
