VMware vMotion is a foundational feature of vSphere that enables the live or hot migration of running VMs from one physical server to another without interruption of downtime. VMware has extended the capabilities of vMotion since its groundbreaking release, increasing performance, extending the distance, and adding additional capabilities from there.
With the release of vSphere 5.1 in 2012, VMware added the ability to performance vMotion without shared storage. This enables the migration of VMs from one vSphere cluster to another vSphere cluster, as long as they are within the same vCenter. This capability is also known as cross-cluster migration.
In 2015 with the release of vSphere 6.0 VMware added the ability to migrate VMs between vCenter Server instances. This capability is known as cross vCenter migration. Leveraging the capability of vMotion, workloads can move between PowerStore X and VxRail, from vVol to vSAN storage, regardless of vCenter configuration.
