Yesterday i completed my first installation of the new Aruba Instant software that supports the 64 IAP's in a single cluster.
I thought i would share my experience as there is a very specific sequence you will need to follow if you are doing this to ensure a smooth installation.
This particular site used 55 IAP-105's and most of these came out of the factory with 220.127.116.11.-18.104.22.168 installed so they were limited to the normal 16 IAP's.
When all of the IAP's were powered up, approx 19 of them showed up on the virtual controller. At this point i completed the upgrade to 22.214.171.124-3001 but found that when the IAP's rebooted, they reset and came back up on 126.96.36.199..
What i think happened is that multiple clusters formed on the network and when the IAP's were rebooting from the firmware update, they connected to one of the other masters that were on 188.8.131.52 and downgrading again.
This seemed to happen in a cycle so there was no way i could proceed other than to disconnect / power down all but one of the IAP's.
I then upgraded the single IAP to 184.108.40.206 and then connected the other back up a few at a time to ensure only one master existed and only a single VC was in operation. Once this was completed with all the IAP's then everything was fine.
So my advice to anybody planning on rolling out more than 16 IAP's:
1) Power up and configure one IAP only
2) Perform upgrade to 220.127.116.11
3) Power up the remaining IAP's
4) Go home earlier than i did!

How about the IAP 93 and 92? it is also unlimited? Because i heard IAP 93 and 92 only support up to 16 units.
During the deployment can i mixture of IAP 105 and IAP 175 to achieve of unlimited IAP deployment?

I believe you can mix and match 105/135 upto the 64 device limit but as soon as you put a 92/93 in the cluster it scales down to 16.
haven't tested this myself but that is how i believe it to work.

The 16 IAP limit for the IAP 104/105, 134/135 and 175 was removed in firmware version 18.104.22.168-22.214.171.124 according to the release notes. I was using 126.96.36.199-188.8.131.52 and found that although more than 16 would join, there would be stragglers that would not--the problem went away after upgrading to 184.108.40.206-220.127.116.11.
