This is a case-study blueprint; no deployment results or customer endorsement are claimed.
Business challenge
A source and target database represent types, keys, timestamps, and transactions differently.
Migration approach
Apply approved field, type, key, and reference mappings with explicit rejection rules. Propose mappings for ambiguous values and investigate source-to-target differences.
Deterministic work
Apply approved field, type, key, and reference mappings with explicit rejection rules. Record rule versions, target constraints, and unresolved exceptions; verify outputs against an agreed baseline.
Agentic assistance
Propose mappings for ambiguous values and investigate source-to-target differences. Review generated proposals before adopting them as implementation or access rules.
Acceptance evidence
Validate precision, nulls, generated keys, relationships, deletes, and application expectations.
Delivery time
The 24 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.
