Abstract
In-service upgrade of software can be achieved efficiently when software modules pass data using message or data queues. The use of data queues facilitates the transition from a software module's old behavior to a new behavior without risking a deadlock or dropped module call. Upgradeable objects connect to process objects that maintain the queues and their state data, and upgrade objects connect to the process objects of their predecessors.
