JCL Migration Analyzer

Analyzes legacy JCL scripts for migration to modern batch processing and workflow orchestration systems like Spring Batch, Apache Airflow, Kubernetes Jobs, or shell scripts.

Overview

This skill provides comprehensive analysis and migration planning for JCL (Job Control Language) batch processing systems. It extracts job structures, converts JCL constructs to modern workflow patterns, maps data dependencies, and generates implementation-ready migration strategies.

Key Migration Focus: JCL to modern orchestration with proper handling of COND logic inversion, data dependencies (DD statements), GDG generations, procedures (PROCs), and batch workflow patterns.

When to Use This Skill

Use this skill when:

  • Analyzing JCL job files (.jcl, .JCL) for modernization
  • Planning migration from mainframe batch processing to modern workflow systems
  • Converting JCL job steps to Spring Batch, Apache Airflow, or shell scripts
  • Understanding JCL COND logic and conditional execution patterns
  • Mapping JCL data sets (DD statements) to modern file operations
