A backup file begins with this line:
#config-version=FGVM64-5.02-FW-build589-
140613:opmode=0:vdom=0:user=admin #conf_file_ver=3881503152630288414
#buildno=0589 #global_vdom=1
Can you restore it to a FortiWiFi 60D?

A.
Yes.

B.
Yes, but only if you replace the “#conf_file_ver” line so that it contains the serial number of that specific FortiWiFi
60D.

C.
Yes, but only if it is running the same version of FortiOS, or a newer compatible version.

D.
No.
