Can't use AP15 on XG

Question

Hi All, 
 i used the Holidays to update my Sopos UTM 9.3 to the new XG 
 There are 2 AP15 on the Network - they are recieving DHCP - Adresses - but are still not visible under Protection - Wireless Protection - Access Points. 
 
 Can i "Reset" the AP 15 - may there is a configuration Probleme caused of the "old config" with my UTM 9.3? 
 
 THX

After Restarting the XG and Updating the Patterns (about 3 Times) know the APs are visible.

Actually, this (specifically adding DHCP Option 234) seems to have solved the problem for me. 
I was running a UTM and XG concurrently (migrating) and the AP would continue to seek out the UTM because they default to the DG for their management source unless the DHCP option 234 is defined otherwise. 
I found this by looking at a network capture of the AP that wouldn't register with the XG and saw a DHCP Opt 234 request from the AP. 
Once I set that to point to the XG, it saw the AP and I was able to register it.
