Automated TELON Migration

Why Modernize?

CA Telon accelerated development for batch and online workloads by generating COBOL, but today organizations face rising vendor costs, limited TELON skill sets, and integration constraints. An automated Telon‑to‑COBOL migration preserves proven business logic while removing vendor dependencies, simplifying maintenance, and enabling future modernization.

Reduce Cost & Risk

Lower license and platform spend; eliminate single‑vendor lockin.

Improve Maintainability

Deliver readable, documented COBOL with standard copybooks and clear I/O layers.

Enable Modernization

Adopt CI/CD, SQL data access, API integration, and cloud‑ready deployment patterns.

Automated Approach

  1. Discovery & Inventory. Parse Telon models, procs, maps, JCL, and external dependencies to build a comprehensive catalog.
  2. Static Analysis. Identify data structures, copybooks, database calls, screen flows, and cross‑program dependencies.
  3. Code Generation. Produce structured COBOL with modular I/O, replacing Telon constructs and generator artifacts.
  4. Data Access Modernization. Optionally replace Datacom/IDMS/VSAM calls with SQL (Db2, SQL Server, or Oracle), or retain existing access patterns when required.
  5. Build & JCL Updates. Generate or update compile/bind steps, link‑edit, and JCL to align with target runtimes.
  6. Test Harness & Equivalence. Create automated test cases and parallel runs that compare reports, files, and key metrics.
  7. Tuning & Cutover Support. Optimize performance, finalize runbooks, and assist with production transition.

Automation accelerates delivery while keeping IT resources in the loop for exception handling and business‑rule validation.
