Wireless Access

We are getting ready to convert APs from 6.5 code to 8 code and are debating using the DHCP option 43 to convert the APs. In the settings on the DHCP for option 43 do we use the Mobility Master IP address or the mobilty cluster VRRP for the building the APs are servicing? 

Cluster VRRP.  The MM does not terminate or talk to any access points.
