I'm trying to upgrade from 6.4.2.6-4.1.1.6_50009 to ArubaInstant_Taurus_6.5.4.3_61959.
The question here is, I'm planning to upgrade it via the GUI, by going into Maintenance > Firmware > Select Image file and then upgrade.
I have 3 IAP-205 in that cluster, by doing that, it will automatically deploy to all 3 of them? is it safe to upgrade them that way?
The idea of the upgrade is to add 2 IAP-305 which will have the same ArubaOS version.
