Migrating a WebSphere Message Broker Version 6.1 broker that is configured on Microsoft Cluster Services (MSCS)

You must complete a specific set of steps to migrate a broker on an MSCS cluster to WebSphere® Message Broker Version 8.0.

Before you start:

Use the following procedure to migrate a broker that is configured on MSCS.

Migrating from WebSphere Message Broker Version 6.1 to WebSphere Message Broker Version 8.0.

  1. Install WebSphere Message Broker Version 8.0 on the same computer as WebSphere Message Broker Version 6.1. Install at least the Broker component; other components are optional. You must specify a new location for this installation.
  2. Open the WebSphere Message Broker Toolkit Version 6.1, and remove the broker from the domain configuration.
  3. Stop all channels that are connected to the Version 6.1 broker.
  4. In MSCS bring the broker resource and WebSphere MQ offline, keeping the cluster disk online on your primary node
  5. Optional: If you have publish/subscribe applications and you want to preserve the publish/subscribe state of these applications, migrate the publish/subscribe information; see Migrating publish/subscribe information to WebSphere MQ.
  6. Optional: If your message flows access user databases by using ODBC connections, update the ODBC definitions to Version 8.0 format; see Updating ODBC definitions when migrating.
  7. In a WebSphere Message Broker Version 8.0 command console run the following command:
    mqsimigratecomponents BROKER1 -m
    where BROKER1 is the name of your broker
  8. With the broker resource offline, move the broker cluster group to the secondary node.
  9. In a WebSphere Message Broker Version 8.0 command console run the following command:
    mqsimigratecomponents BROKER1 -m -1
  10. Copy all additional custom environment settings from your previous environment into your WebSphere Message Broker Version 8.0 environment; for example: MQSI_FILENODES_ROOT_DIRECTORY.
  11. Bring the cluster disk and WebSphere MQ resource offline.
  12. Start the broker cluster group on its primary node.
Migrating from WebSphere Message Broker Version 8.0 to WebSphere Message Broker Version 6.1 .
  1. In MSCS bring the broker resource offline, keeping the cluster disk and WebSphere MQ resource online on your primary node.
  2. In a WebSphere Message Broker Version 8.0 command console run the following command:
    mqsimigratecomponents BROKER1 -s 8.0 -t 6.1
  3. In a WebSphere Message Broker Version 6.1 command console run the following command:
    mqsistart BROKER1

    This step is required to update the Windows service to point at the WebSphere Message Broker Version 6.1 binary files.

  4. In a WebSphere Message Broker Version 6.1 command console run the following command:
    mqsistop BROKER1
  5. With the broker resource offline, move the broker cluster group to the secondary node.
  6. In a WebSphere Message Broker Version 8.0 command console run the following command:
    mqsimigratecomponents BROKER1 -m -s 6.1 -t 8 -1
  7. In a WebSphere Message Broker Version 8.0 command console run the following command:
    mqsimigratecomponents BROKER1 -s 8.0 -t 6.1 -1
  8. In a WebSphere Message Broker Version 6.1 command console run the following command:
    mqsistart BROKER1

    This is required to update the Windows service to point at the WebSphere Message Broker Version 6.1 binary files

  9. In a WebSphere Message Broker Version 6.1 command console run the following command:
    mqsistop BROKER1
  10. Bring the cluster disk and WebSphere MQ resource offline.
  11. Start the broker cluster group on its primary node.

Due to changes in the file security model used in WebSphere Message Broker Version 8.0, you might need to alter the file permissions of the shared resource.

If necessary, create a domain group, add the userID of your broker to this group, and give the group full access to the shared files.
