Part 1: FAQ – Migrating VMs to Hyper-V

Q1. What is Hyper-V?
Hyper-V is Microsoft’s native hypervisor that lets you run and manage multiple virtual machines (VMs) on Windows Server or Windows 10/11 Pro/Enterprise.

Q2. Why migrate to Hyper-V?

• Built into Windows Server (no extra licensing).
• Integration with Microsoft ecosystem (Active Directory, Azure, System Center).
• High availability (Failover Clustering, Replica).
• Cost-effective compared to VMware.

Q3. What migration methods exist?

• P2V (Physical → Virtual).
• V2V (VMware/VirtualBox → Hyper-V).
• Backup/restore migration.
• Export/import if the VM uses VHD/VHDX.

Q4. What tools can I use?

• StarWind V2V Converter (free).
• Disk2VHD (P2V).
• System Center Virtual Machine Manager (SCVMM) (enterprise).
• Azure Migrate/ASR (to the cloud).

Q5. What formats does Hyper-V support?

• VHD and VHDX (preferred).
• VMware’s VMDK must be converted.

Q6. Key considerations?

• Remove VMware snapshots before migration.
• Windows licensing may require reactivation.
• Networking must be reconfigured (VMware vSwitch ≠ Hyper-V vSwitch).

Part 2: Step-by-Step Guide – VMware → Hyper-V

Step 1: Prepare the Source VM

• Shut down the VM in VMware.
• Remove snapshots.
• Record CPU, memory, and NIC settings.
• Copy the VM’s .vmdk file.

Step 2: Convert the Disk

• Use StarWind V2V Converter.
• Input: .vmdk
• Output: .vhdx
• Save to the Hyper-V host.

Step 3: Create the VM in Hyper-V

Hyper-V Manager → New VM → Name → CPU/Memory → Virtual Switch → Use Existing VHDX

Step 4: First Boot

• Start the VM in Hyper-V.
• Windows may re-detect hardware.
• Linux may need Hyper-V integration components.

Step 5: Install Hyper-V Integration Services

• Windows Server 2012 R2 and earlier: Insert services ISO.
• Windows 10/11 and Server 2016+: Built-in.

Step 6: Validate

• Test boot, drivers, networking, apps.
• Check Event Viewer for errors.

Step 7: Cleanup

• Uninstall VMware Tools.
• Apply Windows/Linux updates.
• Configure backups (Windows Server Backup, Veeam, etc.).

Start/Stop

Start-VM -Name "MyMigratedVM"
Stop-VM -Name "MyMigratedVM"

Export/Import

Export-VM -Name "MyMigratedVM" -Path "E:\VMBackups"
Import-VM -Path "E:\VMBackups\MyMigratedVM"

Convert VHD → VHDX

Convert-VHD -Path "C:\VMs\vm-disk.vhd" -DestinationPath "C:\VMs\vm-disk.vhdx" -VHDType Dynamic

Check Resources

Get-VM
Get-VM -Name "MyMigratedVM" | Get-VMNetworkAdapter
