[cisco-voip] UCCX Virtual 9.0(2) to 10.6(1) Upgrade

Fri Aug 21 05:30:13 EDT 2015

I am planning to do the same upgrade this weekend. Do I have to change the
vNIC setting from Flex to VMXNET3 and the guest OS to RHEL 6? The upgrade
guide for UCCX 10.6(1) does not mention any of these and I couldn't find
the OVA readme.
