Before you start to migrate a WebSphere MQ Integrator Broker Version 2.1 broker domain, do the following:
For information about how to use the Control Center to perform this and other tasks, see WebSphere MQ Integrator Broker Version 2.1 Using the Control Center.
For information about how to use this and other WebSphere MQ Integrator Broker commands, see the WebSphere MQ Integrator Broker Version 2.1 Administration Guide.
If two or more of the brokers share the same set of database tables, and you still require these brokers after migration, you must either migrate all of the brokers at the same time or preserve them all at the Version 2.1 level of code.
You do not need to change the configuration of a queue manager that is preserved during migration. You might, however, need to ensure that the WebSphere MQ product code is at the required release and service level to support WebSphere Business Integration Message Broker. At the same time, you might want to ensure that you have installed the other software prerequisites. See Checking software prerequisites for the details.
If you are not able to stop a broker during migration because it is doing critical work, but you want to migrate the broker to the Version 5.0 level of code, create a new Version 2.1 broker on a system on which you are not going to install WebSphere Business Integration Message Broker. Using a Control Center session, deploy to the new broker all the configuration data that was deployed to the original broker. The new broker can then take over the work of the original broker during the migration.
If you intend to preserve any brokers at the Version 2.1 level of code, see Coexistence with previous releases and other products for what you need to consider in this case.
