SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

Migrates legacy COBOL systems by extracting structure, dependencies, and business logic to inform Java-era modernization, enabling a clear migration pathway.

Core Features & Use Cases

  • Program Analysis: Analyze COBOL PROGRAM-ID, divisions, data, and procedure logic to map dependencies and data structures.
  • Copybook & JCL Processing: Extract copybooks and JCL references to generate accurate POJOs and migration strategies.
  • Dependency Mapping: Build a graph of CALLs, copybooks usage, and file dependencies to visualize migration scope.

Quick Start

Provide your COBOL source directory to start automated analysis and generate a migration plan.

FAQPage Schema
How do I analyze COBOL source code to plan a Java migration?▼

To plan a Java migration, you analyze COBOL source directories to extract program structures, JCL jobs, and copybook dependencies, generating a comprehensive modernization pathway.

What is the best way to map COBOL copybooks and JCL references for modernization?▼

Mapping COBOL copybooks and JCL references involves extracting their structures to generate accurate Java POJOs and inform targeted migration strategies across the application architecture.

Can I visualize dependency graphs for COBOL programs before migrating to Java?▼

Yes, you can build a dependency graph mapping COBOL CALLs, copybook usage, and file dependencies to visualize the exact migration scope and extraction requirements.

How does extracting COBOL procedure logic help generate Java architecture?▼

Extracting COBOL procedure logic maps the divisions and data structures, directly translating the legacy business rules into a suggested Java architecture to guide modernization.

Do I need to provide a full COBOL source directory for automated migration analysis?▼

You need to provide your COBOL source directory to start automated analysis, ensuring all programs, JCL jobs, and copybooks are available for accurate dependency mapping.
