oem 12c on hp-ux pa-risc 11.11

I have a question and maybe some of you guys are already doing this(or not). We have some old HP-UX PA Risc(11.11) and i want them monitored with our new OEM 12c(12.1.0.3). Looking at the certification matrix looks like 11.11 is not supported with the 12c agent.

I have one thing i have done in the past, where i wanted to monitor our old pa-risc(11.11) box from Grid control version 11.1.0.7. I was unable to deploy 11g agent as well(due to support issue, pa-risc 11g agent only supported pa-risc 11.23 and 11.31). So as a worked around I deployed 10.2.0.5 agent on that old pa-risc 11.11 box and got it connected to 11g grid control.

Most of these old box run DB version 10.2.0.4 or 10.2.0.5. I am not sure if i can still do this with OEM 12c? where i can either re-deploy(or point them to 12c OEM) 10.2.0.5 agent on these old 11.11 box. Obviously i am sure you guys are probably asking why are you asking here, why not just try it and find out yourself as you have already done this before.

That's were i am stuck. Our team/Management do not want me to do that and they are okay with using 2 different OEM(11g grid of all these old box and 12c for newer version). I think if we can make this work, then we do not have to deal with 2 different OEM versions and everything will be under one umbrella.

I just wanted to post this out here and see what people have to say, so at the least i can point our team/management to right direction.

Is anyone monitoring there old hp-ux pa-risc 11.11 box with OEM 12c, if so what are you doing?

Any pointers would be appreciated.
