In FortiOS 6.0.x, when applying the FortiCarrier license, the FortiCarrier configuration is reset to the factory default settings. With FortiOS 6.2.0 and later, the basic system, interface, and routing settings are retained to avoid a full factory reset.
When you load a FortiCarrier license to FortiOS, the following message is displayed, informing you what settings are retained and not returned to factory default settings:
FortiGate-3000D (global) # execute forticarrier-license DD4K-PVIQ-TEXX-OHAM-XO5T-CHJG-ZQ
This operation will reset the system to factory default except system.global.vdom-mode/system.global.long-vdom-name/VDOMs/system.interface/system.settings/router.static/router.static6!
Do you want to continue? (y/n)
