Windows: Migrating a queue manager to a later version
Follow these instructions to migrate a queue manager from Version 7.1 to Version 7.5.
Before you begin
- Create a migration plan. Use the planning task, Windows: Planning to migrate to a later version as a guide.
- The migration paths to IBM WebSphere MQ Version 7.5
on Windows Vista are listed in Table 1
Table 1. IBM WebSphere MQ Version 7.5 on Windows Vista or Windows Server 2008: supported migration paths From: To: IBM WebSphere MQ Version 6.0 plus fix pack 6.0.2.1 on Windows Vista or Windows Server 2008 IBM WebSphere MQ Version 7.5 on Windows Vista or Windows Server 2008 IBM WebSphere MQ Version 7.0.1 on Windows XP Professional SP2 IBM WebSphere MQ Version 7.5 on Windows Vista or Windows Server 2008 - Review the IBM WebSphere MQ system requirements for Version 7.5; see System Requirements for IBM WebSphere MQ.
- Back up your system before you install IBM WebSphere MQ Version 7.5 over Version 7.1. Once you have started a queue manager you cannot revert to the previous release. If you must restore the system, you cannot recover any work, such as changes to messages and objects, performed by IBM WebSphere MQ Version 7.5. For more information about backing up your system, see Backing up and restoring IBM WebSphere MQ queue manager data .
- Review any other installed SupportPacs for their applicability to IBM WebSphere MQ Version 7.5.
- If you are running on a server with multiple IBM WebSphere MQ installations, that is, IBM WebSphere MQ Version 7.0.1, Fix Pack 6 (or later), you must identify the installation. Make sure that the commands you enter run against the correct installation; see setmqenv.
About this task
Complete this task to migrate a queue manager to IBM WebSphere MQ Version 7.5 from Version 7.1.
All the objects that you previously created are maintained. The components that were previously installed are preselected in the feature options when you install the new level. If you leave these components selected, you can keep them or reinstall them. If you clear any of these components, the installation process uninstalls them. By default, a typical migration installs only the same features that were installed in the previous version installation.
For example, if IBM WebSphere MQ Explorer was not installed in the Version 7.1 installation, it is not installed in a Version 7.5 installation. If you want IBM WebSphere MQ Explorer, select a custom installation, and select the IBM WebSphere MQ Explorer feature on the Features panel. If you do not want IBM WebSphere MQ Explorer, uninstall the IBM WebSphere MQ Explorer feature by selecting a custom installation. Then clear the IBM WebSphere MQ Explorer feature on the Features panel. For more information about how to uninstall features, see Modifying the installation using WebSphere MQ Installation Launchpad.
You can also migrate a Version 7.1 queue manager to IBM WebSphere MQ Version 7.5 on a system where a previous version has been uninstalled. The queue manager data must have been retained, or restored from a backup.
Procedure
What to do next
You might be restoring Version 7.1 on a server with multiple IBM WebSphere MQ installations. If one of the installations is primary, after restoring Version 7.1, the Version 7.1 installation will be by default, the primary. You must review how applications connect to an installation. After restoring Version 7.1 some applications might connect to the wrong installation.
