Business challenge
A modernization team needs to separate business logic from batch and platform assumptions.
Migration approach
Inventory authorized programs, copybooks, job steps, record layouts, encodings, and file dependencies. Explain control flow and prepare bounded target-code proposals for engineer review.
Deterministic work
Inventory authorized programs, copybooks, job steps, record layouts, encodings, and file dependencies. Record rule versions, target constraints, and unresolved exceptions; verify outputs against an agreed baseline.
Agentic assistance
Explain control flow and prepare bounded target-code proposals for engineer review. Review generated proposals before adopting them as implementation or access rules.
Acceptance evidence
Validate packed-decimal and encoding behavior, file contracts, job sequencing, and restart scenarios.
Delivery time
The 40 months (estimated) assumes the stated migration inventory, accessible source definitions, available reviewers, and an agreed target environment. Plan discovery, design, build, parity testing, business review, and release readiness as separate checkpoints. Re-estimate when access, custom features, data issues, or acceptance scope changes.
