Restoring an IBM MQ MQI client to an earlier version on Windows

If you revert an IBM MQ MQI client from a later version of the product to an earlier version of the product, we must undo the configuration changes manually.

About this task

It is unusual to revert earlier IBM MQ MQI client libraries to a workstation. The principal tasks are listed in the following steps.

Procedure

1. End all IBM MQ activity on the workstation.
2. Uninstall the later version of the IBM MQ MQI client code.
3. Follow the client installation procedure for the platform to install the earlier version of the IBM MQ MQI client code.
4. If you configured a Client Connection Definition Table (CCDT) for a queue manager on a later version of the product, revert to using a table created by a queue manager on the earlier version. The CCDT must always be created by a queue manager on the same, or earlier, release to the client.
