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.
- 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.
- Stop all Version 2.1 components.
- Uninstall WebSphere MQ Integrator Broker Version
2.1, excluding
the data.
- Install WebSphere
Message Broker Version
6.0 in a different
location to where WebSphere MQ Integrator Broker Version
2.1 is installed.
- Issue the mqsimigratecomponents command
for the Configuration Manager.
- Start the Version 6.0 Configuration Manager.
- Start the Version 6.0 User Name Server.
- Issue the mqsimigratecomponents command
for the brokers.
- Start the brokers.
- 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.
