This is a case-study blueprint; no deployment results or customer endorsement are claimed.
Business challenge
Multiple source systems need to contribute to an agreed destination without losing provenance.
Migration approach
Apply approved canonical mappings, survivorship rules, source namespaces, and reconciliation controls. Highlight competing definitions and suggest resolution options for data stewards.
Deterministic work
Apply approved canonical mappings, survivorship rules, source namespaces, and reconciliation controls. Record rule versions, target constraints, and unresolved exceptions; verify outputs against an agreed baseline.
Agentic assistance
Highlight competing definitions and suggest resolution options for data stewards. Review generated proposals before adopting them as implementation or access rules.
Acceptance evidence
Retain source identifiers and history; review duplicate decisions, disputed values, and destination ownership.
Delivery time
The 30 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.
