Hi, it is backwards compatible and the agent can talk to multiple management groups (also at different cu levels). This is called multi-homing the scom agent. When the agent gets upgraded to a higher CU level by one of the two mgmt groups the agent will
be updated completely. It is one executable. It just runs two sets of workflows from the two management groups you have talking to it. I have not seen issues with higher scom cu agents talking to lower cu mgmt groups in multi-homing.
