Currently all our guest user accounts are created on a 4402WLC that is running on code 184.108.40.206. This WLC will be replaced by a 5508WLC that is running on 220.127.116.11. Is there a way to export all the guest user accounts and password from 4402 and import them to 5508? I can only get account name from "show running-config" and password is not showing there.
Unfortunately, I do not think there is an easy way to push all configured users to a new WLC.
You can push a batch of users to select WLCs if you import the username/passwords/settings from a .csv file, but my guess is you do not have an up to date .csv file handy.
The other option would be to go with our original plan if you can schedule an upgrade on your 18.104.22.168 WLC.
