Migrating a queue manager to the latest version on IBM i
Follow these instructions to migrate a queue manager on IBM i to the latest MQ version.
Before starting
- Create a migration plan. Use the planning task, Plan migration to the latest version, as a guide.
- Review the IBM MQ system requirements for the latest version of the product; see System Requirements for IBM MQ
- Review any other installed SupportPacs for their applicability to the latest version of the product.
About this task
There are two types of migration:
- The migration takes place on the same machine, optionally accompanied by a hardware upgrade. This migration is referred to as a slip installation. On IBM i, uninstalling the earlier version before you install the later version is optional.
- The migration takes place on a different machine. This migration is referred to as a side-by-side installation.
A side-by-side installation lets you prepare the new environment first, without interrupting the queue manager. It also gives you the limited option of reverting to use the earlier version installation, if the migration is unsuccessful. It is limited, because we cannot restore the queue manager data from the later version. We must restart processing with the queue manager data at the point you stopped the queue manager on the earlier release.
If you decide to do a side-by-side installation, we must prepare the new server first, installing the prerequisite software.
To add Advanced Message Security to the system, we must select Option (2) when you install the product; see Installing Advanced Message Security on IBM i for further information.
- Installation methods on IBM i
Select a slip installation or a side-by-side installation to upgrade IBM MQ for IBM i.- End IBM MQ activity on IBM i
End IBM MQ applications and connections, and remove any unwanted or indoubt messages.- Quiesce IBM MQ on IBM i
Stop all queue managers. If necessary force all queue managers to stop, tidy up shared memory and end all jobs in the QMQM subsystem.- Save IBM MQ data on IBM i

Install the IBM MQ server in its primary language.- Install samples on IBM i
Install the IBM MQ samples- Install translated versions on IBM i
Install translated versions of IBM MQ from a choice of national-languages.- Verify the installation on IBM i
How to check that your installation has been successful.- Verify the upgrade on IBM i
After you have verified the installation, start the IBM MQ subsystem, check the queue managers, and take a fresh media recovery checkpoint.- Restore queue managers after upgrading IBM MQ on IBM i
Complete the side-by-side upgrade by restored the saved queue managers onto the server that we have upgraded.- After Upgrading on IBM MQ for IBM i
