Hyper-V is the path most likely to be quietly cost-free on the hypervisor line, because it ships as a role in Windows Server you may already own. That makes it the natural first stop for Microsoft shops facing a VMware renewal. The work is real, though: every VM gets converted, and your management and backup tooling changes.

The conversion toolchain
Migrating to Hyper-V means converting each VM's virtual disks and swapping VMware Tools for Hyper-V Integration Services. The common tools:
| Tool | Cost | Best for |
|---|---|---|
| StarWind V2V Converter | Free | Straight VMDK to VHDX conversion, smaller estates |
| Windows Admin Center | Free | Browser-based management for Hyper-V hosts and clusters; free alternative to SCVMM for small-to-medium estates |
| System Center VMM (SCVMM) | Licensed (~$1,300/core/yr for System Center) | Managed conversions and ongoing management at larger scale; adds meaningful cost to the Hyper-V savings case |
| Veeam / backup-based restore | Licensed | Restoring VMware backups directly as Hyper-V VMs |
| Azure Migrate | Free | Paths toward Azure Stack HCI or Azure |
Note that Microsoft's old standalone Virtual Machine Converter (MVMC) is retired, so most teams now standardize on StarWind for ad-hoc conversion or a backup tool for wave-based moves with built-in rollback.
The licensing math that decides it
This is where Hyper-V wins or loses. Windows Server is licensed per physical core, and the edition sets your VM rights:
- Datacenter edition: unlimited Windows Server VMs per licensed host. If you run Windows-heavy and already own Datacenter, the hypervisor is effectively free.
- Standard edition: rights for two VMs per license; stacking gets expensive past a few VMs per host, so dense hosts should be on Datacenter.
- Linux VMs: run free on Hyper-V from a licensing standpoint; you still cover the host's Windows Server cores.
Trade-offs to plan for
- Management at scale. vCenter's single-pane experience is replaced by Windows Admin Center or System Center; large estates feel the difference.
- Backup and DR re-platforming. Your vSphere-tuned backup stack needs Hyper-V support or replacement.
- Admin retraining. Day-two operations, clustering, and live migration all work differently from vMotion and DRS.
- Networking. Virtual switches and VLAN/NIC teaming concepts map over but require reconfiguration.
The comparison nobody runs: staying on VMware for less
If the only goal is to stop overpaying Broadcom, a managed VMware provider keeps vSphere intact and avoids conversion entirely, which can be less disruptive than a Hyper-V replatform. Hyper-V usually wins on long-run cost for Microsoft shops; managed VMware wins on speed and zero rework. Our VMware vs. Hyper-V comparison and the full alternatives matrix lay it out.
How to decide
Compare 3-year TCO: status quo (Broadcom renewal × 3) against Hyper-V (one-time conversion plus any incremental Windows Server licensing). For most Windows-dominant shops with a hardware refresh due, Hyper-V pays back fast.

VMware to Hyper-V migration FAQ
What tools convert VMware VMs to Hyper-V?
Common tools include Microsoft System Center Virtual Machine Manager (SCVMM) for managed conversions, StarWind V2V Converter (free) for VMDK to VHDX conversion, Veeam and other backup tools that can restore VMware backups directly as Hyper-V VMs, and Azure Migrate for VMware-to-Azure-Stack-HCI paths. Disks convert from VMDK to VHDX and VMware Tools is replaced with Hyper-V Integration Services.
Is Hyper-V cheaper than VMware?
For most Microsoft-centric shops, yes. Hyper-V is a role included with Windows Server, and Windows Server Datacenter edition allows unlimited Windows VMs per licensed host, so if you already license Datacenter the hypervisor cost is effectively absorbed. That removes the separate VMware licensing line entirely.
What is the catch with migrating to Hyper-V?
The hypervisor is mature, but management tooling at scale is less unified than vCenter. Large estates lean on System Center or Windows Admin Center, and third-party ecosystems (backup, monitoring) differ from vSphere. Plan for admin retraining and for re-platforming backup and DR around Hyper-V APIs.
