Note MQSAgent.dll on the IBM WebSphere MQ server must be updated to the same Cumulative Update (CU) level as on BizTalk Server. To do this, make sure that you run the same CU setup on the IBM WebSphere MQ server. You may experience performance issues if you run mismatched versions.
For more information about BizTalk Server hotfixes, see KB 2003907: Information about BizTalk hotfixes and Service Pack support .
