 - This won't work when SSO is active , you need  a similar procedure as mentioned in this thread : https://community.cisco.com/t5/wireless/management-interface-ip-address-change-in-5508-wlc-cluster/td-p/2693715 , presuming you have an aireos based controller ,

thanks for reply

problem solved by disable sso on both wlc, and disable wlan

Glad you got it working and posting your steps.

That is not going to be easy as you have to break SSO and perform the changes you want and then configure SSO again.  You need to also make sure your access points can discover the new IP of controller, or else you have bigger problems and a longer downtime.  Make sure you update your DNS if you are using any certs also.
