Hi folks,
Thanks for reply, but it was a software version.
I have validate upgrade process with ARUBA, in order to be sure to pass A6000 in 3.3.2.13 to 6.1.3.6.
Aruba tell me i have to pass 3.3.2.13 to 3.4.4.1 and pass 3.4.4.1 to 6.1.3.6.
But in this migration i have about 300 Aps, and 100 Aps stay in down status ... They don't flash and stay in 3.3.2.13...
So to have Ap up, i have to downgrade my A6000, in 5.0.4.10, to have all my AP flash in 5.0.4.10, and once it was ok, upgrade A6000 in 6.1.3.6, to reflash my AP in 6.1.3.6.
So to recover Ap down i have to pass controller in 5.0.4.10, and my goes up...
Once in 5.0.4.10 upgrade in 6.1.3.6 and all works ...
Hope it help you in futur deployments :)
Regards ;)
