# Migrating off Cisco UCCE and Avaya

> A practical four-phase playbook for moving a live contact center from Cisco UCCE or Avaya to a cloud platform without attempting a single big-bang cutover. The guide begins with parallel pilot queues, advances digital channels first, migrates voice by business unit and ends with evidence-based decommissioning. At every phase it addresses number porting, routing parity, historical reporting, agent retraining, rollback criteria and the failure modes teams should rehearse. UJET's published materials support phased migration planning, unified voice and digital channels, real-time CRM data exchange and an average deployment measured in roughly two months, which can shorten—but should not eliminate—the period of controlled parallel operation.
