Migrating a small domain

Before you start

This task is part of the following larger task: See the larger task to understand the context of this task and what you must do before you start this task.

It is likely that on a small domain, many or all components share a single system. In this situation, the simplest approach is to migrate all the components of that single system at the same time. If this is not acceptable, you can install WebSphere Business Integration Message Broker Version 6.0 at a different location on the same system, or on a second system, and migrate each component separately, as Version 5.0 components can coexist with Version 6.0 components within a single domain. See Coexistence with previous versions and other products for more information.

You can migrate components in an order that best suits your environment. For example, a typical order in which to migrate the three major components might be as follows:
  1. Instances of the Message Brokers Toolkit
  2. Configuration Manager
  3. Brokers
Migrating instances of the Message Brokers Toolkit first allows you to begin developing message flows that use features that are new in WebSphere Business Integration Message Broker Version 6.0. Migrating the Configuration Manager allows administrators to prepare your Version 6.0 broker domain for deployment. Finally, migrating the brokers allows you to run your new message flows.

Depending on the goals of migration, the order in which you migrate components can be different. For example, if the primary reason for migration is to make use of new broker functions, you might want to migrate the brokers first. Or, for example, if you plan to move your Configuration Manager to a new platform, you might want to migrate the Configuration Manager first to discover any operating system or environment issues early on.
