Overview

This article explains various use cases when a Nutanix AHV virtual machine is migrated from one cluster to another.

Migration of a virtual machine with the same UUID:

Once you migrate a VM, 

• It will be automatically detected in the new cluster during the next Discovery process, either initiated manually or through automated daily runs. 

• The migrated VM will already be configured as a backup set in the new cluster, ensuring backups continue as scheduled. 

• All previously created restore points (RPs) will be retained for uninterrupted data continuity. 

• The migrated backup set will be assigned to the default pool, but if no proxies are available in the default pool, it will be disabled temporarily.

Migration of a virtual machine with a new UUID:

In the case of VM migration resulting in a new UUID, 

• The VM will be recognized as a fresh entity during the subsequent Discovery process in the new cluster, regardless of whether it's triggered manually or through automation. 

• As it is treated as a new instance, you will need to configure it as a new backup set. For more information on VM configuration, please see Configure virtual machines for backup.

Note: Previous restore points will not be retained, since the VM is considered a distinct entity in this scenario.
