Nutanix Move Overview
Nutanix Move is a tool that allows virtual machine migrations from VMware ESXI, Hyper-V, Azure, and AWS to AHV.
It can also be used to migrate from Nutanix AHV to AWS.
This software works on a virtual machine whose sources are available on the Nutanix website with a customer account.
For optimal use, we recommend installing Nutanix Move as close as possible to the destination.
The Nutanix Move software is the only software that communicates between the source and the destination.
Note: It is strongly discouraged to use Nutanix Move with virtual machines on a Windows Server running Active Directory or Microsoft Exchange. It is best to migrate as recommended by Microsoft.
For VMs that use databases in Microsoft SQL, it is best to stop the database service when completing a migration.
Ensure that the original virtual machine is compatible with the destination Nutanix environment.
Instructions
We will look at how to migrate between a remote environment on Hyper-V to an OVHcloud Nutanix environment.
The source and the destination are on two interconnected private networks through an IPSEC VPN.
Preparing the original virtual machines before migration
The virtual machine must be in the list of supported virtual machines in the compatibility matrix for the migration to work.
Log in to the Nutanix Accounting Matrix site to verify the compatibility of the source machines with the destination environment on Nutanix.
Specificity of virtual machines on LINUX
Some virtual machines will not start correctly after migration via Nutanix Move.
Check the compatibility list as it is likely that the SCSI driver is not supported and needs to be changed with the PCI driver.
In this case, you will need to follow this procedure to change the disk controller of a Virtual Machine after the virtual machine is migrated.
Specificity of the Microsoft environment
Microsoft does not provide the SCSI adapter and network card Virtio drivers. These drivers must be installed before migration. These drivers are available on the Nutanix website with a customer account.
Note: Microsoft Windows 2008 is no longer supported by Microsoft or Nutanix. However, you can install older Virtio drivers and attempt a migration.
Login to the Nutanix website with a customer account to download the VIRTIO drivers.
Enter your user name in Email, your password in Password, and click Log In.
Click the Download link that suits your needs.
For our example, we will download the driver for amd64.
From a Windows virtual machine in the Hyper-V environment, double-click Nutanix-VirtIO-1.1.7-amd64.
Read the license terms and conditions, accept them by ticking the box, and then click Install.
Click Finish to complete the installation without having to restart the virtual machine.
