I upgraded an agent or two to 10.2.0.5, and discovered there is an extra field in one of the tables that is sent to the repository, so the repository needs to be upgraded from 10.2.0.4 (I think). In your situation, if you upgrade OMS, then the 10.2.0.4 agent will send one less field than exists in that same table. I cannot tell you if it will fail or if that will generate [error] messages. Just passing the info along for your consideration. This is all buried in an SR somewhere in the past, so I don't have the specifics.

I'm reading docs and I still have some opened questions: - remote systems using 10.2.0.4 em agent will continue to work? - weblogic server have to be installed after upgrade? Which configuration requires? From metalink matrix I've found that DB may continue to be 10gR2 and need not to be upgraded to 11g Any others experience to share?
