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 you begin

  1. Create a migration plan. Use the planning task, Planning migration to the latest version, as a guide.
  2. Review the IBM MQ system requirements for the latest version of the product; see System Requirements for IBM MQ
  3. 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 you 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 decide to do a side-by-side installation, you must prepare the new server first, installing the prerequisite software.

If you want to add Advanced Message Security to your system, you must select Option (2) when you install the product; see Installing Advanced Message Security on IBM i for further information.
