Lower Virtualization Costs Without Disrupting Operations
A phased VMware-to-Hyper-V migration reduced licensing costs, preserved existing infrastructure, and kept the business operating throughout the transition.
Challenge
A financial services organization faced a significant increase in VMware licensing costs. At the same time, the organization still had substantial value remaining in its existing Dell server and DataCore storage investments, which continued to meet performance and capacity requirements.
The environment also supported a Citrix platform for application and desktop delivery, along with Veeam backup software and ExaGrid backup storage. Replacing these technologies would have introduced unnecessary capital expense, complexity, and operational risk.
The business needed a practical path to reduce virtualization costs without interrupting business services or replacing infrastructure that continued to deliver value.
Business requirements
Reduce ongoing virtualization licensing costs
Preserve existing compute and storage investments
Retain the Citrix environment
Maintain Veeam and ExaGrid backup operations
Minimize disruption to users and applications
Avoid unnecessary capital spending
Solution
The business migrated from VMware to Microsoft Hyper-V using a phased approach designed to maintain business continuity. Hyper-V provided a straightforward platform change because the existing hardware was supported, Microsoft licensing was already owned, and the customer had operated Hyper-V previously.
The solution changed the virtualization layer while retaining the surrounding infrastructure and operational processes.
Existing investments retained
Dell server infrastructure
DataCore shared storage
Citrix application delivery environment
Veeam backup and recovery platform
ExaGrid backup storage
Existing Microsoft licensing
Migration Approach
The migration was performed while the company continued normal operations. Veeam was used to move virtual machines from VMware to Hyper-V in controlled waves, limiting downtime to the workloads included in each planned outage.
Rather than taking the full environment offline, only small portions of the infrastructure were unavailable during scheduled cutovers. This reduced business disruption and allowed application validation to occur incrementally.
The team converted VMware hosts as additional Hyper-V resources were needed. After workloads were moved from a VMware host, that server was rebuilt as a Hyper-V host and returned to service to provide capacity for subsequent migration waves.
Results at a Glance
Business operations continued throughout the migration
Veeam moved workloads between hypervisors
Cutovers occurred during planned maintenance windows
Only affected workload groups experienced downtime
Hosts converted as Hyper-V capacity was required
No temporary compute platform was needed
Why Hyper-V
Hyper-V aligned with both the company’s financial objectives and technical requirements. It allowed the organization to reduce VMware licensing exposure without forcing a broader infrastructure refresh.
Platform fit
Existing Dell hardware remained supported
DataCore storage integration was preserved
Citrix workloads remained on a familiar architecture
Veeam supported migration and ongoing protection
Hyper-V licensing was already paid for
Internal staff had prior Hyper-V experience
Business Outcomes
Reduced Virtualization Costs: The Business avoided the quoted VMware licensing increase and used Hyper-V licensing already owned.
Protected Existing Investments: Dell servers, DataCore storage, Citrix, Veeam, and ExaGrid remained part of the operating environment.
Maintained Business Continuity: The company remained operational while small workload groups transitioned during planned outages.
Minimized Migration Risk: Veeam-enabled migration waves limited the scope of each cutover and supported incremental validation.
Extended Infrastructure Life: Existing hosts were converted as capacity was required, preserving hardware value and avoiding temporary infrastructure.
Preserved Operational Familiarity: Prior Hyper-V experience and retained backup processes reduced the change introduced to the operations team.
Results
The company successfully transitioned from VMware to Hyper-V while keeping the business running. Veeam moved workloads in planned waves, and only the applications included in each cutover experienced limited, scheduled downtime.
As VMware hosts were emptied, the team converted them to Hyper-V and returned them to service when additional capacity was required. This approach allowed the platform to expand throughout the project without purchasing temporary compute resources or replacing hardware that still had useful life.
The completed migration reduced virtualization licensing costs while preserving Dell servers, DataCore storage, Citrix, Veeam, and ExaGrid. The customer gained a lower-cost virtualization platform without a disruptive infrastructure replacement or broad business outage.
Challenge:
Rising VMware licensing costs threatened the economics of an otherwise capable infrastructure.
Solution:
Migrated workloads to Hyper-V with Veeam while retaining Dell servers, DataCore storage, Citrix, and ExaGrid.
Outcome:
Reduced virtualization costs and completed the transition during normal operations with only limited, planned workload outages.
