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.
