Produce a migration plan from [CurrentKeyway] to [TargetKeyway] (restricted keyway or interchangeable core system) prioritizing [CriticalAreas]. Respect change freezes on [ChangeFreezeDates] and maintain service within [BudgetCap]. Address inventory conversion, code system mapping, legacy adapter needs, and phased cutover.
Output requirements:
Gap Analysis (table: Capability, Current, Target, Remediation).
Stakeholder Map (roles, interests, influence, engagement).
Implementation Roadmap (phases, milestones, dependencies).
Cutover Runbook (hour-by-hour steps, backout plan).
Risk Register (risk, likelihood, impact, owner, mitigation).
Post-Implementation Validation (acceptance tests, signoffs, success metrics).
