Taking a look at the KB https://extremeportal.force.com/ExtrArticleDetail?an=000092794, it clearly shows a AP305C with serial 03052008xxxxx (so, by the openbook, an "not-Universal AP", which should be 03052009xxxxxx to work) being converted successfully to WiNG.
But If you try to do it with an AP with the same SN prefix, in my case, 03052008240xxx, it show an error message regarding "Onboarding Failure": "03052008240xxx The device is not a supported Dual-Boot AP.". And by taking a look at the serials, my AP seems to be "newer" than the AP shown on the KB...
I presume the AP shown on the KB is an "internal" access point from engineering, with some extra features, but it seems that the existing 03052008xxx APs should be capable of switching operating modes, but locked by some software feature (or other unknown policy). Is it right????
