IBM® Integration Bus Version 10.0 can coexist with previous versions so that you can test and compare functions that changed between a previous version and IBM Integration Bus Version 10.0. You can then control your migration to IBM Integration Bus Version 10.0 by migrating individual integration nodes one at a time, rather than by migrating all the integration nodes to IBM Integration Bus Version 10.0 at the same time.
Different versions of IBM Integration Bus or WebSphere® Message Broker can coexist and can run independently, and you can migrate integration nodes from one version to another.
Because different versions and releases can coexist, you can migrate to Version 10.0 from an earlier version in a controlled manner, and you do not have to migrate all integration nodes at the same time. For more information, see Migrating.
If you prefer, you can run the mqsiprofile command. By default, this command is stored in C:\Program Files\IBM\IIB\10.0.0.n\server\bin.
If you have installed an earlier version of this product on the same computer, check that the earlier mqsiprofile command is not included in the system profile for the current user ID. The environment that is set up by the mqsiprofile command of a previous version of IBM Integration Bus or WebSphere Message Broker is not compatible with a later version of IBM Integration Bus. To avoid potential problems, consider using a different user ID for each version and add the correct command for each version to the system profile of each user ID. For more information about the mqsiprofile command, see Setting up a command environment
