Installation of IBM MQ client and IBM MQ server for IBM i

When you install an IBM® MQ server on an IBM i system, the client is also automatically installed.

The installed version of the IBM MQ client for IBM i can be refreshed by using a "slip installation" which replaces an existing installation with a fresh image.

Installing a client over an existing client results in a successful installation.

Installing a client over an existing server results in a failure with a CPDB6A4 error.

Installing a server over an existing client results in a successful upgrade of the client to both server and client capabilities.
