An administrator is migrating a virtual machine from a Test cluster to a Production cluster. The two environments do not have any shared storage. What is the easiest way to accomplish this task?

Storage vMotion relocates a VM's disk files to a different datastore while keeping the VM on the same host, so it cannot move the VM across clusters and does not satisfy the cross-cluster compute relocation requirement.

In vSphere 6.x, the migration wizard's vMotion capability supports cross-cluster migration without shared storage by simultaneously moving the VM's compute context and relocating its disk files to a datastore accessible by the destination cluster - all in one operation with no downtime, making it the simplest and fastest approach available.

Virtual-to-Virtual (V2V) migration is a conversion process for moving VMs between different hypervisor platforms such as Hyper-V to vSphere, not for live migration between clusters within the same vSphere environment.

A backup-and-restore workflow using VMware Data Protection requires powering down the VM, running a backup job, restoring to the target cluster, and reconfiguring - a multi-step process far more complex than a single vMotion operation.
