Case Study: Spotless Group achieves zero‑downtime migration of its mission‑critical IT helpdesk to Microsoft Lync with Enghouse Interactive

Spotless Group Migrate to Lync with no Downtime

Spotless Group, an international facilities‑management company, faced a four‑week deadline to move 600 staff into new headquarters and migrate from a 15‑year‑old PBX to Microsoft Lync without disrupting its mission‑critical IT helpdesk. To manage the risk they engaged Zeacom (now part of Enghouse Interactive) and deployed Zeacom Communications Center (ZCC) to provide enterprise contact‑center features during the transition.

Zeacom/Enghouse Interactive implemented ZCC as a bridge between the legacy PBX and Lync, enabling a hybrid rollout so the helpdesk kept operating with no missed calls during the move. The migration of 600 users was completed on schedule with zero downtime, continued support for payroll operations serving over 40,000 workers, and Spotless now runs its helpdesk on a single Lync infrastructure without maintaining the old PBX.
