DHCP Option 43 Question Regarding Changing WLC Management Interface IP Address

We currently have 3 5508 WLCs.  One of the controllers will be moved to a new location soon and when it does, the IP address of the management interface will change.  The IP addresses of the other 2 controllers won't change.  

Is it okay to change the DHCP option 43 entry on our servers before the WLC actually moves?

 

Primary, secondary, and tertiary controller configurations won't be changed until after the WLC moves.

Jason,

   You can change the option 43 at anytime, it should only affect any new AP that comes online. An AP that has already joined a WLC will try to reach the last known WLC before using one of the other discovery methods. If your AP has primary/secondary etc configured it will try all of those before it falls back to discovery.
