Just wondering about these two firmware versions. We are currently ruuning 6.5.4.11 and when I check for updates in the web UI, it advertises 8.3.0.6. I downloaded these files and added them to Airwave's list of firmware images, but when I go to run the upgrade, 8.3.0.6 doesn't show up in the list of available images - I get 8.3.0.5 instead. Is this becaue the current firmware version has to be upgraded to 8.3.0.5 first?
