Abstract
A method for upgrading redundant network components is disclosed. An application is installed on a network component. The network component is related as a redundant peer with a mate network component operating in an active mode and processing a stable call. The network component is placed in a standby mode. Data of a first version is transferred from the mate network component to the network component. The transferred data is converted from the first version to a second version. The mate network component is switched from the active mode to a standby mode. The network component is switched from the standby mode to an active mode to process the stable call.
