  • building a cutover facility for transitioning a first and a second set of subscribers from a first communication system to a second communication system, wherein the cutover facility couples a pre-cut switch to a post-cut switch;

    assigning a route to the pre-cut switch associated with the first communication system for the first and second set of subscribers, each subscriber having a unique directory number;

    assigning a route for the first and second set of subscribers to the post-cut switch associated with the second communication system;

    migrating subscribers in at least one of the first and second sets of subscribers from the pre-cut switch to the post-cut switch;

    identifying a transition midpoint, the transition midpoint being the point when approximately half of the subscribers have been migrated from the pre-cut switch to the post-cut switch; and

    shifting end office traffic routed to the pre-cut switch to the post-cut switch in response to the transition midpoint being identified.
