I'm a little bit confused about what I've read and what I've tested myself regarding the CNUT auto-update feature
Cambium support and the documentation advise that when doing a cluster upgrade the SMs have to be upgraded first
my issue is for some reason, not all SMs will be reachable by their own IP
I've picked up a pilot AP and tried updating the AP and then enabled the auto-update to get the SM upgraded it worked just fine following the upgrade path 11.2->12.1->12.2->13.1->13.4
the pilot Ap has only 2 SM attached to it; my question is am I safe to do it the same way when it will be on a much bigger scale ( 100 SM per cluster )
I'll be very grateful if you can advise based on your own experience
My company made a similar jump this past week, and we have had troubles. Any 430 SM's that were connected to a 430 AP upgraded to the lates 13.4 without an issue. Any 430 SM's connected to the 450 AP's in PMP 450/450i Interoperability Mode did not upgrade past 13.2.1. It says the Bad file image. We have a trouble ticket into Cambium on it and are waiting for a response.
