An administrator needs to migrate a powered off virtual machine to another cluster with no shared storage. What option should be selected?

When migrating a powered-off virtual machine (VM) to another cluster that lacks shared storage, the best option is to change both compute resource and storage. This process involves not only moving the VM to a new cluster but also relocating the associated virtual disks to the appropriate storage within the target cluster.

Changing both compute resources and storage allows for a complete migration of the virtual machine, facilitating the placement of the VM on the desired host within the new cluster while also ensuring that the storage is configured correctly for that environment. Since there is no shared storage between the clusters, the virtual disks need to be copied or moved to a storage location that is accessible within the target cluster, making this option necessary.

In contrast, simply changing the compute resource only would not suffice since the VM's virtual disks would remain in the original storage location, which is not accessible from the new cluster. Choosing to change storage only wouldn't address the need to also migrate the compute resources to the new cluster. The option to migrate virtual machine(s) to a specific datacenter is broader and does not specifically address the storage migration required in this scenario. Therefore, selecting to change both compute resource and storage is essential to ensure a successful migration without any access issues after the operation.
