I have requirment to let PI (7.1) communication with different versions of MQ (5.3 and 6.0). However I doubt that this is possible.
As for MQ, the JMS drivers of the MQ needs to be deployed to PI. For MQ 5.3 and 6.0, different drivers (6.0 has additional jar files as 5.0) are to be packaged into com.sap.aii.adapter.lib.sda and deployed to PI. There is no way you can deploy different version of drivers onto the same PI box. even if you can deploy different version of hte driver to PI box, it won't work in runtime, simply because, when the driver is loaded, there is no way to tell PI class loader which version of class (driver) to load.
how do you guys think of this?
