Generating Agile Ready Backlogs from Legacy Systems using GenAI – PoC

Executive Summary

Migrating hundreds of legacy applications from mainframe to cloud is not just an engineering task, it is a transformation bottleneck that spans requirement discovery, test coverage, and delivery readiness. Many large enterprises face delays due to outdated documentation, incomplete test suites, and the manual effort needed to translate legacy logic into Agile-ready artifacts.

To address this, a GenAI-powered automation engine was developed by Factspan to reverse-engineer business logic, generate structured requirements, create user stories, and auto-draft test cases directly from legacy codebases. Built for scale and auditability, the solution enables faster backlog transformation and accelerates delivery across modernization initiatives

Business Impact:

• ~75–80% reduction in total effort for requirement, story, and test case creation
• 60% improvement in alignment between generated test cases and legacy functionality
• 50% faster test planning cycle for target migration modules
• Higher migration confidence through standardized documentation and validation
