I am using WMB 7006 with a QM at MQ 7504 (primary install) on AIX.
For various reasons I would like to run that QM at 7505 by installing that version of MQ as a secondary installation and then associating the QM to that installation.
However WMB 7 can only use the MQ primary install location - would it be OK to migrate the QM to MQ 7505 in this way, whilst leaving the broker using the MQ 7504 libraries?
Does anyone see any issues with this?

That should work for all applications using the MQI.
Multi-install will transparently redirect the application's MQI calls to the correct stubs for the qmgr's version. |

You will need to make sure the broker will fail over to the same machine as the queue manager.
Broker uses bindings connections, so it must always run on the same machine as the queue manager.
Unless it's a v10 broker. |

These are all on the same AIX host and in the same HA RG.
I know that WMB 7 has particular restrictions with regard to (lack of) multi-version MQ support due to the way it loads the MQ libraries.
However I was hoping that just a fixpack level difference would not fall foul of this issue.
Thanks for replies - anyone from WMB development care to comment?

isn't the queue manager still a pre-requisite for multi-instance broker in V10 ?
