Reducing Legacy Modernization Time from Eight Months to Two Through Intelligent Code Reverse Engineering

Customer Overview

A leading global financial institution relied on mission-critical COBOL applications to support core banking and financial operations developed over several decades. These systems contained complex business logic that remained essential to daily operations but had become increasingly difficult to understand, maintain, and modernize due to limited documentation and shrinking availability of specialized legacy expertise.

As digital transformation initiatives accelerated, the organization required a faster and more reliable approach to interpret legacy code, uncover business rules, and prepare its application landscape for modernization without disrupting critical financial operations.

The Challenge

Legacy COBOL systems represent decades of accumulated business knowledge. Understanding relationships between programs, data structures, and processes requires extensive manual analysis by specialists. This manual dependency makes modernization initiatives costly and slow.

A lack of explicit documentation further complicates reverse engineering. It increases project timelines and creates risks from incomplete logic mapping.

The organization faced several challenges:

Extensive manual effort to analyze complex COBOL applications

Limited visibility into source code and business rules

Heavy dependence on scarce legacy technology specialists

Long modernization timelines delaying digital initiatives

High project costs from manual reverse engineering

Difficulty preparing legacy applications for downstream modernization

The Solution

Scry AI implemented its Reverse Engineering of COBOL & PL-1 for Financial Institutions solution to automate the analysis and interpretation of legacy enterprise applications.

Intelligent code analysis

The platform automatically analyzes COBOL programs. It maps exact relationships between source code, business logic, and underlying data elements.

Automated dependency mapping

The system automatically connects source and target data points. This process replaces manual code reviews and makes hidden dependencies explicitly visible.

Structured insight generation

The solution generates structured insights detailing application behavior. Modernization teams can then understand complex legacy systems with significantly less manual investigation.

Modernization readiness

Converting undocumented application logic into actionable intelligence reduces dependency on specialized experts. This provides a reliable foundation for future application migration and integration.
