Whitepaper: Modernize legacy systems before your expertise disappears

Legacy modernization projects fail 74% of the time and the engineers who understand your COBOL, mainframe, and legacy systems are retiring faster than you can replace them.

The Large Codebase SDK from OpenHands fills that gap. By combining AI coding agents with static analysis, it maps the full dependency structure of your codebase and orchestrates migration work in the right order so agents can run in parallel without producing conflicting changes, making enterprise-scale refactors practical for the first time. Model-agnostic and deployable on-prem or in the cloud, it's built for organizations where data sensitivity and regulatory compliance aren't optional.

What you'll learn in the whitepaper:

Why 74% of modernization projects fail (and what’s actually missing)
How dependency-aware orchestration unlocks safe parallel refactoring
How AI agents bridge the legacy + modern expertise gap
Architecture of the OpenHands Large Codebase SDK
Real-world workflows for migrating COBOL and large systems
How to evaluate if your system is a fit
