I am upgrading 2 WAE and a central manager box from 4.0.13 to 184.108.40.206. I have done all the backups and am preparing to do the disk check. I have a few questions before moving forward.
When I reboot these things, will the site experience an outage?
Should I have someone onsite in the event that something breaks? I am about 3000 miles away from the sites to be upgraded.
