For what it's worth, we started running the v8 code about a year ago. We did the initial rollout with hands-on help from Aruba engineering as part of the early adopter program, which was very helpful in adapting to the new new code. Given how major of an update it was, it's been relatively painless for us. The new cluster upgrade has been particularly nice in recent versions, to the point where most users don't even notice it.
I would recommend that you look closely at your memory utilization before taking the jump. We had a pair of 7240 controllers that were running at about 50% memory utilization under 6.4, but after moving to 8.x it jumped up to > 90%. We ended up taking advantage of the 7240XM trade-up program to double the memory, and they've been mutch happier since.

Thank you for taking the time to early adopt to help Aruba figure it out. We are waiting patiently to move to AOS8 but are getting anxious as we want to implement some of the new features.

We’re looking at an upgrade without MM for our small Campus. 280 WAPs that will grow to ~400 using a high density design using 7220 & 7210. Still investigating the cost/benefit for MM or non-MM upgrade. We’ll need more Q & A with HPE and our local vendor. Can’t make Atmosphere due to scheduling conflicts.

We are currently on 8.2.0.2 which has been running since it was released.
