Case Study: Global Bank Achieves 70% Faster Legacy Analysis with Xebia Ace

Global Bank reduces legacy analysis effort by 70% with Xebia

The customer, Global Bank, faced the challenge of modernizing its 25-year-old legacy portfolio and model management systems. The critical business logic embedded within the platform was undocumented, creating significant complexity and risk for the modernization program. To address this, the bank partnered with vendor Xebia and utilized its AI-Native digital engineering framework, Xebia Ace™.

Xebia implemented an AI-enabled legacy modernization accelerator powered by Xebia Ace™ and Claude Opus 4.5. This solution systematically analyzed the legacy code to extract and document all hidden business rules, workflows, and validations. As a result, Global Bank reduced its legacy analysis effort by 60-70%, achieved backlog readiness within weeks, and significantly lowered its dependency on scarce subject matter experts, creating a trusted foundation for its modernization roadmap.
