Hi, thanks for the reply.   Two AP's were connected to a controller (version 5) but now I want to move the AP's to another controller using a new DNS name.  This controller is currently shutdown and a new controller and the new domain name is running.  I did not "Forget" the AP's before I shutdown the old controller.

  @Jellyhead It's hard to do it remotely without any other thing.

A simple way: ask your stuff connect a PC to the EAP site router, and you can do Teamviewer/Anydesk to remote manage the PC. Then use EAP local IP to login, and if this is an EAP with recently firmware, there will be a RESET option on it's web interface. After resetting the EAP, login again and set up Controller IP.
