I have 60 GHz installed in parallel with 5.7 for failiver, one has a much higher ospf cost on the router to router link.
The problems: severe rain will cause 15-20 seconds of intermittent packet loss and terrible performance before the 60 link drops entirely. Let's say the link drops at -64 Rain bursts will take rssi to -67 for 2-3 seconds at a time and then a brief lull in rain had the rssi at -60 or -58. Repeat in 20-30 second cycles. The ospf failover is not instant. The 60 link can be planned with the same ospf cost metric as a patch cable because it is FDD and line rate. The 5GHz link is at best 200 Mbps and definitely not FDD.
