I moved back to 18.5 MR1 because of AP15 issue. Now, I decided to move back to 19 EAP1, and all the configuration I have made on 18.5MR1 are lost. DHCP does not show logs, for example. I previously create AP15 as host and it is not there. I deleted the AP15, Wireless networks and these changes are back again.
This is a normal behavior?
