So , at my thread i've trouble with 2 unit AP (didn't Sync), it was because i missed some configuration on AP. but as suggestion , we are upgrade the OVA,Package, Firmware . here for the steps :
Clean Install with OVA 1.6.1-r10
Upgrade the Firmware for All AP (CnPilot 400/410) to 3.7.1-r4
Update package to 1.6.3-r15
Backup configuration from the Old one (CnMaestro)
Deployed the New OVA with the same IP Address configuration
Upload the backup configuration on CnMaestro
Change to mode DHCP (see attachment IP Mode)
All the AP has sync
so Many thanks to @Ashok for assisting me until solved this problem. and thanks for cambium forum.
