SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams migrate COBOL legacy code to modern Java or C# by providing source analysis, deterministic code transformation, test case generation, and diff verification, reducing manual effort and risk.

Core Features & Use Cases

  • Deterministic COBOL parsing and AST generation to guide migration.
  • Automated Java/C# code generation with naming conventions and type mappings.
  • Test case generation and diff verification to ensure behavioral parity.
  • Use Case: Migrate a COBOL module handling customer records to Java/C# and validate outputs against original COBOL results.

Quick Start

Run the cobol-migration skill on your COBOL source to generate Java/C# artifacts and test suites.

FAQPage Schema
How do I migrate COBOL code to Java or C#?▼

To migrate COBOL code to Java or C#, this Skill automates source analysis, generates modern code with type mappings, creates test suites, and verifies output parity to ensure production-ready artifacts.

What is the best way to convert COBOL legacy code to Java?▼

Converting COBOL legacy code to Java is best handled by deterministic code transformation, which parses the source, enforces naming conventions, and generates test cases to validate behavioral parity.

Can I automate COBOL to C# migration for an entire project?▼

Yes, you can automate COBOL to C# migration for project-wide conversions, handling data types and program structures while generating test suites to compare outputs against original results.

How does COBOL code transformation handle ambiguous logic during migration?▼

COBOL code transformation handles ambiguous logic by applying deterministic mapping rules during analysis and flagging those specific parts for manual review to ensure migration accuracy.

Does COBOL to Java migration generate test cases for validation?▼

Yes, COBOL to Java migration generates test suites and performs diff verification to compare outputs, ensuring the modernized code maintains behavioral parity with the original legacy system.

What do I need to validate COBOL to C# code conversion results?▼

To validate COBOL to C# code conversion results, you need the generated test suites that perform diff verification, comparing the new outputs against original COBOL results to confirm parity.
