Thanks @Leo Laohoo for the insight
as per checking on CCM the only software release is 8.2
can we upgrade later using SNTC service ?
WLC must be running 8.10.X.X -- I cannot be more clear than that.
If the controller "has to" be on 8.2.X.X then convert, at least, one 9130ax into Mobility Express. All the other 9130ax will be controlled by the ME.
