We have a production SZ-124 we need to move from an old network to a new segment. From other posts I've read the best way to do this is to run an AP CLI script to "set scg ip " on all the APs before you change the controller's management IP.
We also plan on updating the DNS entry used for discovery.
One challenge we have is that a lot of our APs are in customer spaces and aren't always online. After we move IPs, if a previously offline AP comes back online after the change - will it go through the discovery process again?
I just realized that this isn't such a big deal because any offline APs could be migrated manually with a direct SSH session whenever they come back online. I should be able to just follow the other IP migration advises seen in other threads.
