At work we used to run such a machine with 9.1 and 10.2. My colleague tells me 10.3 gave errors, but he does not remember what. The machine is not in use anymore, because of other upgrades, so I can't verify for you. Any reason not to try 11? I don't know if it fixes anything, but it would be a nice data point for comparison.
