IBM Integration Bus Version
9.0 requires a
specific minimum supported version of WebSphere® MQ.
You must first install a supported version of WebSphere MQ and migrate your WebSphere MQ resources to this version. You
can then install IBM Integration Bus Version
9.0. If
you are migrating from WebSphere Message Broker Version
6.1,
see Migrating the Version 6.1 WebSphere Message Broker component for more information about
how to manage the WebSphere MQ migration. For the latest details of all supported levels of hardware and software, visit the 
IBM Integration Bus Requirements website.
There are two different ways to migrate your broker components. You can use parallel broker migration to associate the application logic on your existing broker with a separate Version 9.0 integration node (broker). Choose this option if you prefer not to stop the broker (to avoid problems for your business applications) or if you want to reproduce the broker function on another computer.
Alternatively, you can use in-place broker migration to migrate your existing broker components immediately to IBM Integration Bus Version 9.0. You do not need to change your client configurations because the existing broker is migrated in-place to Version 9.0 on the same computer. However, you must stop your broker while migration takes place. For more information, see In-place broker migration.
Parallel broker migration with previous versions of the product installed on the same computer
IBM Integration Bus Version 9.0 can coexist with any previous version of WebSphere Message Broker on the same computer during parallel broker migration.
Component names must be unique on the computer, regardless of version.
When you migrate from a previous version of WebSphere Message Broker to IBM Integration Bus Version 9.0, you do not have to uninstall the previous version of the product before you install Version 9.0. You can install Version 9.0 in a different location on the same computer, migrate your components and resources to Version 9.0, and uninstall the previous version of WebSphere Message Broker later, when you are sure that you no longer need it.
For details of default locations for installations of each version, see Coexistence and migration.
If you attempt to install IBM Integration Bus Version 9.0 into a directory that already contains an installation of WebSphere Message Broker, you are prompted to cancel the installation and select a different directory to preserve your existing configuration.
If you install more than one version on a single computer, and you create multiple components, check that sufficient memory and disk space are available.
When you have installed Version 9.0, you can test your configuration.
Restrictions on coexistence of Version 9.0 components with previous versions
The following restrictions apply.
- The IBM Integration Toolkit Version 9.0 works only with brokers that you migrated to, or created in, Version 9.0. If you try to connect to brokers at an earlier version, the connection attempt fails. However, you can use the IBM Integration Explorer to connect to Version 9.0, Version 8.0 and Version 7.0 brokers.
- You can run all programs that you wrote to the CMP at Version 8.0, Version 7.0 or Version 6.1 to interact with brokers that you migrated to, or created in, Version 9.0. Programs that start, stop, delete, and monitor deployed resources continue to work with Version 9.0.
- You can deploy BAR files that you created in an earlier version of the WebSphere Message Broker Toolkit from the IBM Integration Toolkit Version 9.0 to a broker at Version 9.0, without making any changes to the BAR files.
- You cannot deploy resources that you compiled in the IBM Integration Toolkit Version 9.0 to brokers that are at a previous version.
- You cannot share the IBM Integration Toolkit Version 9.0 workspace or source projects with previous versions of the WebSphere Message Broker Toolkit. For more information, see Migrating development resources to IBM Integration Toolkit Version 9.0.
Coexistence with SupportPac IS02
The SupportPac IS02, IBM Integration Explorer Plug-in, cannot coexist with the IBM Integration Explorer in IBM Integration Bus Version 9.0. If you previously installed SupportPac IS02, you must uninstall the SupportPac before you install the IBM Integration Explorer Version 9.0. To remove SupportPac IS02, delete or move the directory to which you extracted the IS02 zip file that was supplied with the SupportPac. Delete the BrokerExplorer.link file that you copied into the C:\Program Files\IBM\WebSphere MQ\eclipseSDK33\eclipse\links\ directory.
