You cannot migrate from the Windows on x86 product (any version) to the Windows on x86-64 product. Similarly, you cannot migrate from the Linux on x86 product (any version) to the Linux on x86-64 product. You must re-create the integration nodes (brokers) from scratch.

| From ... | You can migrate to ... |
|---|---|
| WebSphere® Message Broker Version 6.11 | IBM Integration Bus Version 9.0 |
| WebSphere Message Broker with Rules and Formatter Extension Version 6.11 | IBM Integration Bus Version 9.02 |
| WebSphere Message Broker Version 7.03 | IBM Integration Bus Version 9.0 |
| WebSphere Message Broker with Rules and Formatter Extension Version 7.03 | IBM Integration Bus Version 9.02 |
| WebSphere Message Broker Version 8.04 | IBM Integration Bus Version 9.0 |
You can migrate from WebSphere Message Broker Version 8.0, Version 7.0 or Version 6.1 only to a full edition of IBM Integration Bus Version 9.0, Remote Adapter Deployment, Express Edition, or Standard Edition. Do not migrate brokers from an earlier version to the Developer Edition. If you choose to migrate brokers by using the mqsimigratecomponents command, the broker is migrated in its current mode. If you purchased the Remote Adapter Deployment, Express Edition, or Standard Edition, you must change the mode of all your migrated brokers to comply with the terms of your license. For more information, see Changing the operation mode of your broker.
- You can migrate Version
6.1 products
at Fix Pack 3 (Version 6.1.0.3) or later. During the migration of WebSphere Message Broker Version
6.1 to IBM Integration Bus Version
9.0, you must upgrade
your WebSphere MQ installation to a supported
version. For more information about migrating from WebSphere Message Broker Version
6.1 to IBM Integration Bus Version
9.0 at the same
time as upgrading your WebSphere MQ installation,
see Migrating the Version 6.1 WebSphere Message Broker component.
If you are using WebSphere Application Server with IBM Integration Bus, or you have publish/subscribe applications that use the SubIdentity option, you must upgrade WebSphere Message Broker Version 6.1 to Fix Pack 9 before you can migrate to IBM Integration Bus Version 9.0.
- You can migrate to IBM Integration Bus Version 9.0 only if you do not use the additional features that are provided by Rules and Formatter, or you choose not to use them after migration. To take advantage of equivalent functionality in Version 9.0, you must redesign your applications.
- You can migrate Version 7.0 products at Fix Pack 5 (Version 7.0.0.5) or later, but you must first ensure your WebSphere MQ installation is at a supported version, by upgrading if necessary.
- You do not need to apply maintenance to your WebSphere Message Broker Version 8.0 installation before you migrate to IBM Integration Bus Version 9.0, but you must first ensure your WebSphere MQ installation is at a supported version, by upgrading if necessary.
