Nutanix Move is a tool that allows you to migrate VMs from different sources to Nutanix AHV with minimal downtime and complexity. Nutanix Move supports migration from Hyper-V to AHV, including VMs configured for UEFI-boot. UEFI stands for Unified Extensible Firmware Interface, which is a standard for the software interface between the operating system and the firmware. UEFI-boot is a mode of booting that uses UEFI instead of BIOS (Basic Input/Output System) to load the operating system. UEFI-boot offers some advantages over BIOS-boot, such as faster boot time, larger disk support, and better security features1.

To migrate a VM configured for UEFI-boot from a Nutanix Hyper-V cluster to AHV, you need to use Nutanix Move and follow these steps2:

Download and deploy the Nutanix Move appliance on the AHV cluster.

Log in to the Nutanix Move web console and add the source Hyper-V environment and the target AHV environment.

Create a migration plan and select the VMs that you want to migrate. You can choose either automatic or manual preparation mode for the migration.

Start the migration plan and monitor the progress. The migration plan will perform data seeding, which is the process of copying the VM data from the source to the target in the background.

When the data seeding is complete, perform a cutover, which is the process of shutting down the source VMs and powering on the target VMs. The cutover will also configure the boot device for the UEFI-boot VMs on AHV.

Verify that the migrated VMs are working as expected on AHV.
