Abstract
A method for migrating from an old communication switch to a new communication switch is provided according to the invention. The old communication switch interfaces between a packet telephony network and a circuit switched telephony network. The method includes configuring the old communication switch to signal the new communication switch and swinging one or more logical links from the old communication switch to the new communication switch until all logical links between the circuit switched telephony network and the old communication switch have been swung.
