Implement the solution using the graphical user interface

Implement the solution in this scenario involves using the graphical user interface to migrate from an earlier release of IBM MQ, running on a Windows operating system, to a later release, also running on a Windows operating system, then verifying that the queue managers and queues have been successfully migrated to the later release.


Before starting

To try out the scenario, first follow the instructions to set up a copy of the sample messaging infrastructure as described in Create a sample initial IT configuration. This sample configuration is based on IBM MQ Version 9.1.


The migration process described in this scenario shows migrating a queue manager from IBM MQ Version 9.1 to IBM MQ Version 9.2.

The scenario includes two options for the migration method. We can choose to try out one or the other of these options, or both.

    Option 1: Single-stage migration

    In single-stage migration, the installation of the later version of the product replaces an earlier version in the same installation location.

    The advantage of single-stage migration is that it changes the configuration of a queue manager on the earlier version as little as possible. Existing applications switch from loading the libraries from the earlier version, to loading the libraries of the latest version, automatically. Using this approach, the system will be unavailable for the entire process.

    Option 2: Side-by-side migration

    In side-by-side migration, you install the later version of IBM MQ alongside an earlier version. The queue managers continue to be associated with the earlier version until we are ready to migrate them to the later version.

    With the side-by-side approach, because you uninstall the earlier version before starting any migrated queue managers in the later version, we can assign the installation of the later version to be the primary installation.

  • Create a sample initial IT configuration
    This scenario was developed using a sample initial (IT) configuration. Follow the instructions to set up this sample configuration to try out the scenario in the same way as it was originally developed.
  • Option 1: Single-stage migration
    Option 1 of this scenario shows how to migrate from an earlier to a later version of IBM MQ when using the single-stage migration method. With a single-stage migration, the installation of a later version of IBM MQ replaces an earlier version in the same installation location.
  • Option 2: Side-by-side migration
    Option 2 of this scenario shows how to migrate from an earlier to a later release of IBM MQ when using the side-by-side migration method. With a side-by-side migration, you install the latest version of IBM MQ alongside the earlier version that we want to migrate from. Queue managers and applications continue to be associated with the earlier release until we migrate them to the later release.
