I have recently upgraded my BigIP from 10.2.3 to 10.4.0. When I make the newly upgraded box the active node, all of the SNMP monitors that were created to monitor the Virtual Servers turn from yellow to red. I've checked and the OIDs in SNMP and they're identical on the upgraded box and the non-upgraded box. I'm not entirely sure what's happening here. I can provide more information if needed.
