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 |
| System Center VMM (SCVMM) | Licensed | Managed conversions and ongoing management at scale |
| 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.
