A method for pre-staging data includes obtaining a DST configuration of a virtual volume at a first point in time. The method also includes creating a Point-in-Time copy (PiT) in a destination storage pool when the virtual volume includes at least one PiT, or reconfiguring at least one virtual volume segment to contain a hot-spot. The virtual volume may or may not have PiTs. The method further includes recording the DST configuration, specifying the DST configuration be applied to the storage array at a second point in time, and applying the DST configuration to the storage array at the second point in time.
