Problem
Enterprises that rely on mainframe, IBM i, or other legacy applications face opaque codebases, hidden dependencies, and costly, risky modernization projects that often require extensive rewrites and cause service disruptions. Inability to safely expose legacy functionality hampers integration with modern cloud services and slows digital transformation. The lack of automated tools for mapping and migrating these systems leads to prolonged timelines and high migration costs.
Solution
OpenLegacy offers an AI‑driven platform that automatically discovers and maps legacy system dependencies, then generates standardized, documentation‑rich APIs without requiring code rewrites. The platform enables a phased, hybrid migration strategy where legacy and modern services run in parallel, eliminating downtime and reducing risk. Generated integration bridges can be deployed to any cloud or on‑prem environment, providing technology‑agnostic flexibility. Built‑in safety planning, testing, and continuous monitoring ensure that business operations remain uninterrupted throughout the migration. By delivering usable APIs within days, OpenLegacy accelerates time‑to‑market and lowers overall modernization expenses.
Target Audience
Primary customers are large enterprises—such as banks, insurers, and other organizations—that operate critical mainframe or legacy applications and need to integrate these systems with modern cloud architectures while avoiding downtime.
Features
- AI‑powered analysis that securely connects to mainframes/IBM i, automatically maps dependencies, and defines safe modernization boundaries
