Reverting a client to an earlier maintenance level on Windows

For a client, the way in which you revert to an earlier maintenance level depends on whether your client installation was installed from the server DVD or eImage, or from the MQC8 IBM® MQ Clients SupportPac.

About this task

If your client installation was installed from the IBM MQ server DVD or eImage, you can revert to an earlier maintenance level by rolling back the fixpack installation.

Important: Client only installations installed from the MQC8 IBM MQ Clients SupportPac cannot be restored to an earlier maintenance level on Windows. If you need to do this, you must first uninstall the currently installed version of the client and then reinstall client at the appropriate earlier maintenance level.

Procedure

To revert to an earlier maintenance level for a client installation that you installed from the server DVD or eImage:

Log on as an Administrator.
Remove the maintenance either interactively or silently (see Windows: Removing maintenance level server updates).

To revert to an earlier maintenance level for a client only installation that you installed from the MQC8 IBM MQ Clients SupportPac:

Uninstall the current version of the client as described in Uninstalling IBM MQ on Windows.
Reinstall the client at the earlier maintenance level.
