Decide which databases and queue managers you want to preserve. When you migrate, you delete all the components of WebSphere MQ Event Broker and
drop all the database tables used by the Configuration Manager and
the brokers. However, to simplify the task of configuring the new broker domain,
you can preserve the databases and queue managers used by the brokers you
want to migrate. If you are migrating a single broker domain from WebSphere MQ Event Broker to WebSphere
Business Integration Event Broker, you can also preserve the database
and queue manager used by the Configuration Manager, and
the queue manager used by a User Name Server.
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 Event 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.
