Abstract
A production upgrade is described for a multiprotocol gateway. This upgrade allows various modules and components within the gateway to be upgraded independently without impacting traffic flow in the gateway. The upgrade can be performed by deploying a new version of the module alongside an older version of the same module. New client requests can then be directed to the new version, while requests requiring the older module can be continued to be serviced by the prior version. A distinction is made between stateless and stateful conversation during the upgrade of various components. For stateful conversations, request traffic can be versioned according to the session to which each request belongs. A highly available state storage scheme allows new versions of the module to consume state information used by the older versions. For stateless conversations, all new requests can be immediately routed to the new version of the module.
