We're currently running version 8.4.0.4 on our IAPs - the 'new version available' message indicates that 8.6.0.2 can be installed. The question I have is: can you upgrade straight from 8.4 to 8.6 or do you have to do an upgrade to 8.5 first? The reason I ask is that I tried going directly from 8.4.0.4 to 8.6.0.2 using AirWave and the download to the IAP never took place, so I'm wondering if you can't do that.
