The Java Agent 4.4 would have 2 very important enhancements for my use-case</P> <UL> <LI>support for the&nbsp;Apache Async HTTP Client</LI> <LI>enhanced support for Kafka (and Akka)</LI> </UL> <P>My question: will I be able to profit from these enhancement by just upgradeing the agent to 4.4, but leave the controller at 4.3.5.7? Only a very small minority of the agents really need those enhancements, so I would like to upgrade only those few machines, and not the whole environment</P> <P>Thanks!<BR />CU, Joe</P> Fri, 24 Nov 2017 14:16:46 GMT Joe__Ammann 2017-11-24T14:16:46Z https://community.splunk.com/t5/Splunk-AppDynamics/AppD-Java-agent-4-4-with-4-3-5-7-controller-will-it-work/m-p/730936#M7346 <P>Hi</P> <P>we're currently using AppD 4.3.5.7 and I just read the new release notes of 4.4.

The Controller version must be equal to or greater than the versions of any agents connecting to it.</P> <P>No joy, I guess...</P> Fri, 24 Nov 2017 14:22:03 GMT https://community.splunk.com/t5/Splunk-AppDynamics/AppD-Java-agent-4-4-with-4-3-5-7-controller-will-it-work/m-p/730937#M7347 Joe__Ammann 2017-11-24T14:22:03Z https://community.splunk.com/t5/Splunk-AppDynamics/AppD-Java-agent-4-4-with-4-3-5-7-controller-will-it-work/m-p/730938#M7348 <P>You're right Joe.</P> <P>You'll need to upgrade your Controller to 4.4 before you can leverage the 4.4 agents.</P> <P>Regards,</P> <P>Brian Wheeldon</P> Mon, 27 Nov 2017 22:21:14 GMT https://community.splunk.com/t5/Splunk-AppDynamics/AppD-Java-agent-4-4-with-4-3-5-7-controller-will-it-work/m-p/730938#M7348 Brian_Wheeldon 2017-11-27T22:21:14Z
