It will vary considerably based on your bandwidth and how many times your APs would have to try to download the image over the WAN. Have you ever attempted this upgrade before?
I would do a standard upgrade, because live upgrades would take much longer depending on your bandwidth and AP density.

Subject: expected upgrade time for 4 7220 ?
Hi new for Aruba
I need to upgrade 4 7220 with 380 AP on each controller on a single cluster.
From 8.6.0.7 to 8.7.1.9
I have AP type 205 304 305 365 505
The MM & controller are on central DC but the AP's are mostly in the EU..
How long the service window should be ?
How much down time the AP has ?
