I'm fairly new to the Aruba world and I have recently 'inherited' an A200 running 3.1.1.4 that had several AP-93's bought for it. Long story short, it was discovered the 93's wouldn't provision without first upgrading the controller to more recent code (suggested 5.0.4.2 as apparently the 200's cannot run release 6 or higher).
I am wondering what the best course of action would be in upgrading, as I'm a little nervous about just hitting the controller with 5.0.4.2 straight up.
Would it be best to incrementally upgrade to 4.something first (or 3.something) and do the upgrade in a 2 or 3 step process, and if so, would anyone have suggestions which versions would allow for the safest "stepped approach"?
