Microsoft Cluster Server (MSCS) users

 

WebSphere MQ V6.0 and WebSphere MQ V5.3 contain components that provide MSCS support that were previously shipped in SupportPac™ MC74. If you install WebSphere MQ V6.0, you no longer need the SupportPac and you should not install it. The files included with WebSphere MQ V6.0 supersede those in the SupportPac.

If you are using SupportPac MC74 with your previous version of WebSphere MQ, uninstall before you install WebSphere MQ V6.0. We can upgrade the machines in your cluster without losing your configuration parameters by upgrading to WebSphere MQ V6.0 using a rolling upgrade, that is, upgrade each node in turn, waiting for one to complete before starting the next node.

If you want to install WebSphere MQ V6.0 into a different directory from that used by WebSphere MQ, we cannot use a rolling upgrade.
