Migrating from Version 2.1 to Version 6.0: Version 6.0 replacing Version 2.1

This topic describes one of three migration scenarios that are available to you when migrating from WebSphere MQ Integrator Broker Version 2.1 to WebSphere Message Broker Version 6.0.

Before you start:

Before you migrate a broker, ensure that you do not have any aggregations in progress. When you migrate a broker to Version 6.0, any live data that is being stored for aggregations in progress will be lost.

In this migration scenario, all of your Version 2.1 components are on the same computer. After migration to Version 6.0, you no longer need to keep Version 2.1 installed.

  1. Use the Control Center to export all Version 2.1 message flows, message sets, and user-defined nodes. See the WebSphere MQ Integrator Broker Version 2.1 Administration Guide for more information.
  2. Stop all Version 2.1 components.
  3. Uninstall WebSphere MQ Integrator Broker Version 2.1, excluding the data.
  4. Install WebSphere Message Broker Version 6.0 in a different location to where WebSphere MQ Integrator Broker Version 2.1 is installed.
  5. Issue the mqsimigratecomponents command for the Configuration Manager.
  6. Start the Version 6.0 Configuration Manager.
  7. Start the Version 6.0 User Name Server.
  8. Issue the mqsimigratecomponents command for the brokers.
  9. Start the brokers.
  10. Import all Version 2.1 message flows, message sets, and user-defined extensions using the mqsimigratemsgflows and mqsimigratemsgsets commands.
After you have completed the migration, see the post-migration tasks for information about tasks that you might want to perform after migration.
