About Mitel
Mitel is a global market leader in business communications, providing Unified Communications as a Service (UCaaS) to more than 70 million business users in over 100 countries. With 30 data centers worldwide, Mitel’s operations are always-on and mission-critical.
The Business Challenge
According to Rick Cirigliano, Senior VP of Cloud Operations at Mitel:
With 30 data centers globally, high OpEx and CapEx expenditures and longer lead times to bring innovations to market, the company looked to cloud services to overcome these issues and leverage more advanced IT infrastructure and services.

Why RiverMeadow
Mitel is a global market leader in business communications, providing Unified Communications as a Service (UCaaS) to more than 70 million business users in over 100 countries. With 30 data centers worldwide, Mitel’s operations are always-on and mission-critical.
Seamless Migration, Zero Downtime
With a migration scope of 1,000 VMs, speed and stability were non-negotiable. At peak, the team was migrating up to 200 VMs per week.
Through RiverMeadow’s expertise and services-led approach, the migration timeline was reduced from nine months to under six months, with zero disruption to Mitel’s 24/7 global operations.
The Right Tools for the Job
Not all use cases were suited for standard tooling like HCX. That’s why RiverMeadow leveraged its proprietary Migration Platform, offering the flexibility and speed required to meet aggressive timelines and contract-bound maintenance windows.
Impact Across the Business
After completing the migration, Mitel realized:
- A 4x increase in monthly operational output
- Reduced OpEx and CapEx
- Standardization of global service delivery
- Accelerated time to market for new UCaaS services
- Improved security controls and business continuity
What’s Next
Following the successful U.S. data center migration, Mitel is planning to expand its cloud footprint to Europe and Australia, with an additional 350 VMware workloads set to move to Google Cloud.
