When you upgrade from 11.4 or 11.5 to 11.6 configuration while you have a virtual of type DHCPRELAY, the configuration loading will fail.
The impact of this issue is that configuration load will fail until you fix the issue.
The user must have DHCPRELAY virtual for this to happen.
Manually go in bigip.conf and remove the udp{} profile and instead add dhcpv4 or dhcpv6 profile under this virtual. Also, you need to set the mode of operation (relay or forwarding) in that profile you are attaching. Forwarding mode work with unicast DHCP traffic, while Relay mode works with Broadcast or multicast traffic.
