In Master - Local set up if we do any configuration ( VirtualAP,AAA) configurations it will be automatically synchronized with local controller right?? - But in case of MASTER/MASTER configuration how it will sync ?? do we ned to configure in both controllers manually ? , for ex If we add a new VIrtual AP do the other master also will be configured or need to configure the same virtual AP in other master also manually ??

Hi NightShade, you can try using master-master with 2 VRRP using 2 VLAN within each controller, Master01 will be Active on VLAN1 and Master02 will be active on VLAN2.
Share the APs among the VLAN, when one master down, APs will be redirected to other controller.
Something like this
Master 1 :
- VLAN1 : VRRP-Active
- VLAN 2: VRRP-Standby
Master2 :
- VLAN1 : VRRP Standby
- VLAN2 : VRRP Active
Goodluck!
This deployment consists independent master controllers which means you will not have synchronization between the masters, however, the load is shared among the controllers.
For synchronization you either need to use active-passive master redundancy or master-local redundancy.
On the other hand the cost would be the same with the independent master deployment because each of the controllers should be able to terminate the total number of AP's in order to provide full redundancy.
If the customer has 40 AP's probably they are using a 3400 controller. If they would use two controller to share the load then each controller should have 20 AP's which can be done with a 3200 controller, however, if one of these fails only 12 AP can be connected to the other controller.
Based on this in my opinion the customer should use active-passive master redundancy which provides failover and synchrozation also.
