Now that everything is ready, it is time to migrate the virtual machines from the old Hyper-V and ESXi clusters to the new Nutanix AHV cluster using the migration plans previously created.

The different states

A migration plan can be in different distinct states depending on the stage of the migration:

• Not Started: You have created the migration plans but have not yet started them
• In Progress: The migration plan is launched, the data is starting to be replicated.
• Ready to Cutover: The data migration is complete, Nutanix Move continues to synchronize the changes, the virtual machines are waiting to be switched to the target cluster.
• Paused: You have paused the process for some reason. The data migration is suspended.
• Failed: Error during the process of preparing the machines in general. The anomaly must be corrected in order to resume the operations.
• Completed: The virtual machines that have been successfully migrated.

Starting migrations

If you have planned to start one of your migration plans like me, you should already have virtual machines in “Ready to Cutover” status.

This means that they are ready to complete their migration.

For other pending migration plans, you need to start them manually. To do this, check the box in front of the migration plans you want to start, click on the “Action” menu at the top of the list and click on “Start”:

The migration plan starts to execute:

If you followed all the steps correctly, the migration plan should go smoothly. You can track the progress of the plan on the corresponding line, and of the virtual machines in the boxes at the very top:

By clicking on the “2 VMs” in the banner, you will have a step by step guide for each virtual machine:

You can get more details on the operations carried out in the “Events” menu at the top right of the interface:

Synchronizing the data with the new cluster is the longest step of the process and will depend on the volume of your virtual machines.

The cutover

The cutover is the operation that will allow you to finalize the migration from the old cluster to the new one.

You can only perform a Cutover on virtual machines that are in the “Ready to Cutover” state:

To check the status of the virtual machines and proceed with the cutover, click on the “2 VMs” in the “Ready to cutover” frame:

You will then have the list of VMs ready to switch to the new cluster. You can do them all at once, or one by one, it doesn’t matter. It’s up to you. I will migrate Ubuntu_4 by checking the box at the beginning of the line and then clicking on “cutover”:

Validation is required to start the process:

The failover process only takes a few minutes during which Nutanix Move will:

• Power off the VM
• Create a final snapshot
• Synchronize it with the target cluster
• Create the target VM
• Clean up the source VM (disconnect network cards)
• Delete all snapshots created by Move
• Consolidate the virtual machine disks
• Clean up the target VM

The migration status for this virtual machine then changes to “Completed” and I find it on my Nutanix AHV, started and functional:

The virtual machine is successfully migrated, I just have to do all the others.
