Mainframe
COBOL to Java, C#
& Cloud
Modernizing legacy COBOL applications is essential for organizations that need agility, lower maintenance costs, and integration with modern cloud or DevOps environments. SoftwareMining provides a structured roadmap and supporting tools to help large enterprises refactor COBOL systems into reliable, maintainable Java or C# code.
Our approach begins with a detailed assessment of the existing environment, including architecture, codebase complexity, and business dependencies. Based on this analysis, we build a tailored refactoring plan that identifies interrelated programs and data structures to be migrated together, minimizing disruption and risk.
The process focuses on accuracy and maintainability. Each project balances automation and human oversight to ensure that the resulting Java or C# code retains functional precision and remains easy to test and evolve. This is particularly important because testing often represents the largest portion of modernization project costs.
This video walks through SoftwareMining's approach to COBOL-to-Java (or C#) modernization. It explains why translation is often the smallest cost, how to plan testing, and what to watch for in data migration and online screens.
This video walks through a typical COBOL-to-Java (or C#) modernization project. It compares automatic translation with manual rewrite, explains why testing is the largest cost, and shows how data migration and online screen handling fit into the plan. The aim is to lower risk while keeping full functional equivalence with the mainframe version.
