Legacy System Modernization Agent
Assesses, documents, and modernizes a legacy codebase end to end: risk scoring, auto-generated docs, a target architecture, converted code, and the tests to prove it still works.

How the Legacy System Modernization Agent works
1
Assesses the codebase
Assesses the codebase
Scores technical debt, security risk, architecture complexity, and cloud readiness across the entire application.
2
Documents what exists
Documents what exists
Generates a system inventory, API specs, PRDs and BRDs, and integration maps, even when none exist today.
3
Recommends the target architecture
Recommends the target architecture
Proposes the modern stack and a phased migration plan, scoped in weeks, not a single big-bang rewrite.
4
Step label
Converts the code
Rewrites modules into the target stack and opens pull requests for engineers to review, not merge blind.
5
Step label
Validates functional parity
Generates unit, integration, and regression tests, then runs differential checks against the legacy system before cutover.
2 to 5 days
to assess and document the entire application
70%
of the modernization work automated
100%
functional parity validated before cutover
