certificates, you must also back up the local certificate and private key in a password-
protected PKCS12 file. Before restoring the configuration, you must import the
PKCS12 file and set the local certificate name to the same that was in the original
configuration.

exchanging personal information.

local certificate and private key. For more information, see the FortiGate CLI Reference Guide.
