Migrating a queue manager to a later version on IBM i
Follow these instructions to migrate a queue manager from an earlier release to a later release.
Before you begin
If you decide to do a side-by-side installation, you must prepare the new server first, installing the prerequisite software.
- 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 release of the product; see System Requirements for IBM MQ
- Review any other installed SupportPacs for their applicability to the latest release of IBM MQ.
About this task
There are various 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 of the product 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 gives you the option of preparing the new environment first, without interrupting the queue manager. It also gives you the limited option of reverting to use the earlier release installation, if the migration is unsuccessful. It is limited, because we cannot restore the queue manager data from the later version. You must restart processing with the queue manager data at the point you stopped the queue manager on the earlier release.
If you want to add Advanced Message Security to your system, you must select Option (2) when you install the product; see Install Advanced Message Security on IBM i for further information.
