Hi,
wondering if APM enterprise manager is backward compatible in terms of agents? I have a situation where I need to instrument an app running on weblogic 10.3 (IBM JDK 1.6 on AIX) and the Introscope agent 10.5.1 throws the following exception:

In this situation if I have to use older introscope agent e.g. 9.7, will that work fine with 10.5 apm server?
thanks,
