Planning to migrate multiple domains from Version 6.0

Migrate multiple domains that perform different functions in your environment.

A typical configuration for WebSphere® Message Broker is to use a set of three or more domains, consisting of development, test, and production domains.
Development domain
In a development domain, message flow developers create message flows and unit test them in a sandbox environment. The brokers in the domain are not responsible for handling business-critical data.
Test domain
Message flows in the development domain are eventually promoted to a test domain, where message flows are tested against recent, but not live, production data in a realistic broker configuration.
Production domain
When message flows in the test domain are considered to be sufficiently robust, they are promoted to the production domain. This domain is responsible for performing actual business transactions, and message flows in the domain work with live data. Non-critical updates to production flows usually take place only at predefined service intervals.

Development and test domains must be migrated before production domains. Migrating the development domain first minimizes potential downtime associated with any migration activity. In addition, development domains typically require access to new broker functions before test and production domains. When you develop message flows that make use of new functions, you must migrate the test and production domains before you deploy the new message flows to them.

Because each Message Broker Toolkit can administer multiple domains, be careful when migrating instances of the Message Broker Toolkit not to affect any domains that have not been migrated yet.

Message Broker ToolkitVersion 6.1 can administer Version 6.0 domains; similarly, Message Broker ToolkitVersion 6.0 can administer Version 6.1 domains

Before you start to perform migration, back up your resources.
