Migrating data from an old storage device to a new storage device includes creating new paths to the new storage device, freezing old paths to the old storage device, transferring metadata corresponding to the old storage device to the new storage device, where state information is transferred from the old storage device to the new storage device, and thawing the new paths. In one embodiment, a ballizing unit having a distal end removably coupled to a ballizing member moves the ballizing member from a first position within the bore hole to a second position. Insulated gate bipolar transistors are provided that have a voltage blocking substrate. The digital controller is operable to schedule the operation of the digital transceiver path, and to inform the concealment device of start and end points of the activity of the digital transceiver path.
