Data Center Consolidation: 3-Site Infrastructure Migration

A regional financial services firm needed to consolidate three aging data centers into a single co-location facility to reduce cost and improve resilience. The migration involved 200+ servers, multiple line-of-business applications, and strict uptime requirements driven by regulatory and client SLA obligations.

Embedded a senior infrastructure PM to own the full migration program — from inventory and dependency mapping through cutover sequencing and hypercare. Developed a phased migration schedule with defined rollback procedures for each workload. Coordinated across IT infrastructure, application owners, networking, and the co-lo provider to maintain communication and accountability.

All three sites fully decommissioned within 8 months. Zero unplanned downtime during any migration window. Annual infrastructure cost reduced by $620K. Program completed 3 weeks ahead of original schedule.
