Firepower 2110 Changing device from Platform Mode to Appliance Mode?

[karimz963]

Hi Team,

I'm  trying to understand whether device running/startup-config will be erased after migrating Firepower 2110 from Platform to Appliance mode?  or does it reset the FXOS config only? as this is all done remotely and trying to minimize disruption Please see below warning.

Firewall2110(config)# fxos mode appliance
Mode set to appliance mode
WARNING: The running-config must be saved and the system must
be rebooted for this command to take effect. Upon reboot, the current
configuration will be erased, and the default configuration for
appliance mode will be applied.

I have looked at so many documents but just can't find it explained in layman’s terms. Any help would be much appreciated. 

Kind regards

Sorry about my initial question stating " running/startup-config " , doesn't make sense I meant startup-config. 

Thanks

It will wipe the configuration of the fpr or asa instance, so you need a console connection.
