This is a case-study blueprint; no deployment results or customer endorsement are claimed.
Business challenge
Operational logic is spread across Python, Perl, shell, and platform-specific scripts.
Migration approach
Inventory arguments, file formats, exit codes, environment variables, and supported syntax transformations. Explain undocumented logic and propose maintainable replacements with exception handling.
Deterministic work
Inventory arguments, file formats, exit codes, environment variables, and supported syntax transformations. Record rule versions, target constraints, and unresolved exceptions; verify outputs against an agreed baseline.
Agentic assistance
Explain undocumented logic and propose maintainable replacements with exception handling. Review generated proposals before adopting them as implementation or access rules.
Acceptance evidence
Compare input/output contracts, resource limits, failure signals, and rerun behavior without exposing secrets.
Delivery time
The 23 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.
