Thank you, Colin.
We are generally very careful with our upgrades, only upgrading when it appears there is a benefit, or if it's been too long since our last upgrade. In our current world, staying on old firmware for too long represents an unacceptable security risk, in our view.
In addition, whenever I have opened a support case, if I tell them I'm on old firmware, most of the time they tell me to do the upgrade before we can proceed with the case. So, very often, our troubleshooting ends with a check for new firmware and an update if there is some available, BEFORE opening a support ticket.
We went ahead and used the automatic upgrade today, and all went smoothly. The issue we were having appeared to be resolved, as well, but it remains to be seen if it was a result of the firmware or the resulting reboot. If we continue having issues, we will open another thread.
Thanks again.
