Uninstalling the earlier version
Uninstall the earlier version of the product using the Windows control panel.
Before starting
Before starting this task, we must first stop the queue managers, close IBM MQ Explorer and stop IBM MQ as described in Stopping the queue manager.
About this task
In this task, you uninstall Version 9.1 using the Windows control panel. The queue manager data is not removed as part of the uninstallation process, which means that the sample queue managers used in this scenario are retained and can be detected when you install the newer version of the product.
Procedure
- Open the Windows Control Panel by clicking Start > Control Panel > Uninstall a program.
- In the Programs and Features window, find the entry for the installation that we want to remove, for example IBM WebSphere MQ (Installation1), and click Uninstall. The uninstallation process begins and runs to completion. When the process completes, Version 9.1 is removed from your computer and is no longer displayed in the list of programs.
Results
The earlier version of the product has been removed from your computer. However the queue manager data has not been removed.
What to do next
You are now ready to make IBM MQ Version 9.2 the primary installation as described in Making IBM MQ Version 9.2 the primary installation.
