Before you start
WebSphere MQ Event Broker and WebSphere MQ Integrator Broker might be installed on the same system, or there might be no system in the two domains on which both products are installed. You can use the procedure that follows in either case.
To migrate a WebSphere MQ Event Broker Version 2.1 broker domain and a WebSphere MQ Integrator Broker Version 2.1 broker domain into a single WebSphere Business Integration Message Broker Version 5.0 broker domain, do the following:
For information about how to use this and other WebSphere MQ Event Broker commands, see the WebSphere MQ Event Broker Version 2.1 Administration Guide.
The broker database tables are listed in the WebSphere MQ Event Broker Version 2.1 Administration Guide.
On a Windows system, select the option to uninstall including data.
At the point where you import the message flows that you exported from the WebSphere MQ Integrator Broker broker domain, import also the message flows that you exported from the WebSphere MQ Event Broker broker domain.
Deploy migrated message flows to a test environment first of all. When you are sure that they are working correctly, you can then deploy them to a production environment.
Note that the migration does not preserve the subscriptions and retained publications at the WebSphere MQ Event Broker brokers. To recreate this information after migration, subscribers must renew their subscriptions and publishers must republish.
