Enterprise Transformation at Industry-Leading Financial Services and Data Processing Provider
The Customer
A U.S.-based financial services and data processing enterprise.
The Challenge
The customer wanted to rewrite its highly complex, massive, and monolithic legacy application written in COBOL, Assembler and JCL—including the analysis and extraction of its core business rules—to Java. The system was comprised of over 25,000 programs across 50 million lines of code within one application.
The Approach
The AveriSource Platform™ enabled this enterprise to immediately gain insight and knowledge into its large legacy portfolio, supporting an Accelerated Rewrite™ of a complex mainframe application via generation of business rule reports and other application artifacts.

- Application Overview
- Connections
- Clusters
- Data Lineage
- Data Source File Mapping
- Dependencies
Analyze
Using AveriSource Analyze, they identified, analyzed and extracted core business rules, while reducing technical debt and optimizing a complex codebase. The results delivered use cases and requirements documentation to support an Accelerated Rewrite™️ of the highly complex mainframe application to a modern, Java-based architecture.
