1. A computer system for managing communications between client computers and systems network architecture resources, the computer system comprising: one or more processor units and one or more computer readable storage devices that store program instructions, wherein at least one of the one or more processor units executes the program instructions to: identify the systems network architecture resources that each of a set of client computers communicates with based on configuration information stored on each of the set of client computers regarding use of the systems network architecture resources by each of the set of client computers; configure a group of servers to host communications between each of the set of client computers and the systems network architecture resources based on a schedule to migrate the communications between each of the set of client computers and the systems network architecture resources at different times, wherein the set of client computers communicate with the group of servers via an internet protocol and the systems network architecture resources communicate with the group of servers via a systems network architecture protocol; and modify the configuration information stored on each of the set of client computers to use the group of servers for communicating with the systems network architecture resources.
