Its does, in the sence of a save restore for a VM instance.
If you want to upgrade a H/W appliance we don't provide public information on how to do this, we mandate that this is done by a qualified Aruba Engineer and even then its contolled to a select number.
Please advise on your exact requirements?
To add:- the biggest part of this exercise is testing.... if you need to migrate a h/w apliance, we STRONGLY reccomend spinning a 6.x VM and performing a simple save restore as detialed in my guide at the above location.... then test test test.... once we migrate a h/w appliance its a total once-way-street.
