We've not run into any post-upgrade operational problems so far. The only 'excitement' we've encountered is some automatic FPGA upgrades between some images. No problems with that process to date, but it does cause some nail biting as the router takes 10-15 minutes to complete this process and a couple of extra reboots. Fans tend to spin up 100% while this happens, something to be mindful of if you have a power budget.
