Plan migration from legacy CDP to Data Cloud with parallel run

Real World Scenario

Enterprise runs Adobe CDP and new Data Cloud contract; CMO wants Big Bang cutover in 90 days without losing active journeys.

Expected Answer

• Parallel run period with segment parity validation metrics • Identify journey dependencies on legacy segment APIs early • Migrate identity rules first — segments second — activations last • Freeze new legacy CDP use cases during migration window • Rollback plan with legacy segments maintained read-only • Staff training on new segment builder before cutover • Success criteria: match rates, activation volumes, campaign KPIs within tolerance
