This section informs you about what to expect when migrating virtual machines within a datacenter, by using the vCenter Server migration options.
vMotion
vMotion moves a virtual machine's state and configuration to another host while the machine's disks remain in the same location on shared storage.
vMotion of Agent for VMware is not supported and is disabled.
vMotion of a virtual machine is disabled during a backup. Backups will continue to run after the migration, but will be managed by the agent on the target host. If there is no Agent for VMware on the target host, a new agent will be deployed.
Storage vMotion
Storage vMotion moves virtual machine disks from one datastore to another.
Storage vMotion of Agent for VMware is not supported and is disabled.
Storage vMotion of a virtual machine is disabled during a backup. If a backup starts while storage vMotion is in progress, storage vMotion fails. Backups will continue to run after the migration.
