WebSphere MQ and migration to IBM Integration Bus Version 10.0
Options for WebSphere MQ integration when you migrate to IBM® Integration Bus Version 10.0.
Support for WebSphere MQ is extended in IBM Integration Bus Version 10.0, introducing greater flexibility in the interactions between IBM Integration Bus and WebSphere MQ; see Enhanced flexibility in interactions with WebSphere MQ and WebSphere MQ topologies.
As part of your migration process, you might want to configure your IBM Integration Bus Version 10.0 deployment to take advantage of the greater flexibility.
In IBM Integration Bus Version 9.0 or earlier, the integration layer of your architecture must contain WebSphere MQ queue managers. If you have WebSphere MQ queues that you use in integration applications, you must have an existing WebSphere MQ topology in which application messages are routed to the queue manager that is specified on the integration node by using WebSphere MQ channels, remote queue definitions, and distributed messaging. It might be possible to simplify your system so that your message flows interact directly with remote queue managers, which might simplify the WebSphere MQ topology that you need to manage. This simplification requires that you redesign your message flows and your WebSphere MQ topology, and is more than just a migration of your existing solution. However, you might want to include these activities as part of your migration plans.
To determine which components of your existing deployment are using capabilities that require WebSphere MQ queue managers to be a part of the integration layer of your IBM Integration Bus Version 10.0 architecture, and which components are using capabilities that can integrate with WebSphere MQ application queues on a remote queue manager, see Installing WebSphere MQ.
Depending on whether you can change your WebSphere MQ topology during the migration process, you have the following options for migrating integration nodes:
