IBM MQ and migration to IBM App Connect Enterprise Version 11.0
Options for IBM MQ integration when you migrate to IBM App Connect Enterprise Version 11.0.
Greater flexibility was introduced in IBM Integration Bus Version 10.0 in its interactions with IBM MQ; IBM App Connect Enterprise Version 11.0 maintains this enhanced flexibility. See Enhanced flexibility in interactions with IBM MQ and IBM MQ topologies.
As part of your migration process, you might want to configure your IBM App Connect Enterprise Version 11.0 deployment to take advantage of the greater flexibility.
In IBM Integration Bus Version 9.0, the integration layer of your architecture must contain IBM MQ (or IBM MQ) queue managers. If you have queues that you use in integration applications, you must have an existing IBM MQ (or IBM MQ) topology in which application messages are routed to the queue manager that is specified on the integration node by using IBM MQ (or IBM 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 topology that you need to manage. This simplification requires that you redesign your message flows and your 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 IBM MQ or (IBM MQ) queue managers to be a part of the integration layer of your IBM App Connect Enterprise Version 11.0 architecture, and which components are using capabilities that can integrate with IBM MQ application queues on a remote queue manager, see Installing IBM MQ.
Depending on whether you can change your IBM MQ topology during the migration process, you have the following options for migrating integration nodes:
