High Availability SSO Management IP address changes

[sun.ramalingam]

I want to change the management IP addresses  of the WLCs which are Wism modules and are in SSO HA deployment , Is it possible to change the IP addresses without breaking the SSO , is there any documents availble stating the steps , Thanks

As per my experience: you need to break/disable SSO.

I would suggest to do this task via console Access:

1. config redundancy mode disable (this will disable the SSO)
2. config wlan disable all  (to disable the WLANs)
3. config interface address management <new IP> <new Mask> <gateway>
4. Also change the the IP of the redundancy management interface because its need to be in same subnet as management.
5. config interface address redundancy-management <new IP > <new IP for the peer redundancy management interface>
6. config redundancy mode sso (Enable SSO again)

7. config wlan enable all (to enable all wlans)
