Upgrading an IBM MQ client installation using the GUI installer

How you upgrade an IBM® MQ client installation on Windows to a newer version, release, or modification, using the GUI installer.

Before you begin

Ensure that you have:

Stopped all your IBM MQ applications
Shut down your listeners
Stopped all your queue managers. If the queue manager is part of a cluster, suspend the queue manager before you stop it. For more information, see Maintaining a queue manager in a cluster.
Backed up your data

Access the IBM MQ installation image.

See Where to find downloadable installation images.
Locate Setup.exe in the Windows directory of the IBM MQ installation image.
Start the installation process.

Either run Setup.exe from a command prompt, or double-click Setup.exe from Windows Explorer.

Note: If you are installing on a Windows system with UAC enabled, accept the Windows prompt to allow the launchpad to run as elevated. During installation, you might also see Open File - Security Warning dialog boxes that list International Business Machines Limited as the publisher. Click Run to allow the installation to continue.

The IBM MQ Installation window is displayed.
Follow the instructions on screen. When you click the Launch IBM MQ Installer button, if you see a panel asking you to choose between installing a new instance, or maintaining or upgrading an existing instance, select Installing a new instance.
On the next panel, choose between Install leaving the existing installation(s) untouched or Upgrade an existing named installation already on the machine, and click Next.

Attention: If you do not see this screen, it means that there was no IBM MQ client installation on the machine that could be upgraded by this installer.
Follow the installer prompts to upgrade your IBM MQ client installation.
