Case Study: Leicestershire County Council achieves near‑zero downtime server, SAN and Hyper‑V migration with Vision Solutions' Double‑Take Move

Leicestershire County Council - Customer Case Study

Leicestershire County Council, the municipal authority serving more than 60,000 residents from Glenfield, UK, needed to replace ageing Sun servers/SAN and move from VMware to Microsoft Hyper‑V to save about £20,000 a year. Because many critical, custom applications run across two mirrored clusters with shared storage, a traditional unload/reload migration (requiring days of downtime) and previous unreliable tools were unacceptable.

Dell GICS managed a migration using Vision Solutions’ Double‑Take Move, which performed a background initial copy and continuous real‑time replication so cutovers were scheduled, reversible and nearly instantaneous. Completed in under three months, switchovers took under 30 minutes per server (20–30 servers per night), with virtually no downtime, maintained application availability, reduced labour and vulnerabilities, and delivered the planned £20,000 annual savings.
