Abstract

A sequence for distributing at least one of a plurality of code packages to the at least one facility according to different states of a fixed state machine is set. The at least one of the plurality of code packages is installed in at least one staging area. The at least one of the plurality of code packages is maintained in the at least one staging area in a valid, dormant mode while the fixed state machine is stopped. Pursuant to a resumption of the fixed state machine at a subsequent time, a current code package is swapped with the at least one of the plurality of code packages in the at least one staging area to activate the at least one of the plurality of code packages.
