I upgraded from WCS to NCS 1.0 today and when I looked at the home screen I noticed that my controller was red. I went into "Configure/Controllers" and saw that the status next to my controller was "Unreachable". After researching what could be wrong I removed the controller from NCS. I then went in and readded it. I didn't get any errors and now when I look at "Configure/Controllers' I don't see any controllers. If I try to add it again I get the message that the controller already exists.
Ys I did. After the import the controller shows as red/unreachable. I removed the controller and tried readding it. I noticed that the controller didn't show up in my devices list. I finally found it under the "Unknown devices". Apparently there was a problem with the SNMP GET request. I verified that the SNMP community string was in the SNMP communities on the controller for the IP address of the NCS appliance. Still no luck as I get the same error when trying to update the device credentials in NCS.
Have you tried restarting the NCS or restarting the services? I ran into an issue like that but not during a WCS to NCS migration. When I upgraded WCS to a newer version. WCS seemed I keep the old data even thought it was not showing up in WCS. I will have to look for my fix. Can't remember but I think it was doing something with the DB.
I tried restarting NCS before I deleted the controller. No luck so that's when I deleted the controller to readd it. I've verified that the NCS appliance IP address is in the "SNMP Trap Receivers" and "SNMP Communities" list and made sure both were enabled. Still no luck. The only thing I haven't done is restart the WLC.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
