Migrating from Version 2.1 to Version 6.0: Version 6.0 coexisting temporarily with Version 2.1

This topic describes one of two 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:

In this migration scenario, all of your Version 2.1 components are on the same computer. You want to keep Version 2.1 installed temporarily during and after migration to Version 6.0. You can then stop and uninstall Version 2.1 at any time after migration has been completed.

  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. Install WebSphere Message Broker Version 6.0 in a different location from where WebSphere MQ Integrator Broker Version 2.1 is installed.
  3. Create a Version 6.0 User Name Server using the mqsicreateusernameserver command.
  4. Start the Version 6.0 User Name Server.
  5. Create a Version 6.0 Configuration Manager, using the mqsicreateconfigmgr command, specifying the Version 2.1 database but the Version 6.0 User Name Server.
  6. Start the Version 6.0 Configuration Manager.
  7. Create a Version 6.0 broker using the mqsicreatebroker command.
  8. Start the Version 6.0 broker.
  9. Import all Version 2.1 message flows, message sets, and user-defined extensions using the mqsimigratemsgflows and mqsimigratemsgsets commands.
  10. Stop the Version 2.1 broker immediately after deployment.

When you no longer need to run Version 2.1, stop and uninstall any Version 2.1 components.

After you have completed the migration, see the post-migration tasks for information about tasks that you might want to perform after migration.
