Access Point Migration

CA Spectrum identifies the mobility/migration of Access Points across WLCs. In CA Spectrum when you remove an AP physically from one WLC and connect to another WLC, the Access Point model will be moved from the previous WLC's (source WLC) hierarchy, to the WLC you have subsequently connected to (Destination WLC). This happens during the next polling cycle, of the destination WLC. On successful migration, an AP migration event (Attribute ID: 0x6760001) will be raised on the Destination WLC.

This happens during the next polling cycle, of the destination WLC.
On successful migration, an AP migration event (
Attribute ID: 0x6760001
) will be raised on the Destination WLC.
: AP model is not deleted and recreated during migration (unless you explicitly do so), but same existing AP model is updated with its parent WLC relation.
The 
Access Point Migration Purge Interval (hrs)
 value is set to 24 (hrs), by default. 
You can configure the same from 
WLC Manager
 > 
Information Tab 
> Configuration: WLC Manager.png  
: If Access Point is physically removed from one WLC and is not to attached/migrated to any other WLC within Purge interval, then AP Migration event will not be raised.
