We have a cluster of controllers dedicated to supporting our remote AP environment (1,000 or so RAPs). I'm looking to schedule an AOS upgrade from 8.6.0.5 to 8.6.0.18 (we're limited due to legacy RAP models so sticking with 8.6 for now) but I'm not sure what to expect in terms of downtime or how the RAPs will be selected, as there won't be more than 1 per person. Some may have no clients, so i suspect it'll start with those maybe? I'm just hoping to better understand what I should expect and when I would know if something went wrong.
Thanks!
