SMVI has the capability to restore individual virtual disks (VMDKs) of a VM. This feature also allows disks to be restored to a different datastore. This is referred to as out-of-place restore. This allows VM administrators to test the consistency of the disks before attaching the disk to the VM. SMVI doesn’t attach the restored disks automatically if the VMDK is removed from the current configuration of the VM or restored to a different datastore. Out-of-place restore copies the virtual disk files to the destination datastore after which users have to attach the disks manually.
So you can select the VMDK. Then from the drop down you can select the datastore and click on next.
