A method for handling upgrades of systems comprising two circuit packs which contain memory. In one embodiment, on some trigger signal to a circuit pack, that circuit pack acts as a slave circuit pack, and causes version information for the data stored in the memory of the second circuit pack, which acts as a master circuit pack, to be transferred to the slave circuit pack. If the transferred version information indicates that the data in the slave circuit pack should be updated, the slave circuit pack causes a transfer of information from memory in the master circuit pack to the slave circuit pack, and stores the new information in the memory of the slave circuit pack.
