Convert Firepower 4125 device to ASA

[Brad_Shawh]

Is this even possible?

I followed lot of links explaining how this is done, but there is no 'erase' command on this box.

Firepower 4000 series and 9300s require you use the Firepower Chassis Manager (FCM) to change or replace the logical device. FTD and ASA instances are logical devices in this context.The 4000 series only supports a single logical device while the 9300 can have multiple.

So you would delete the FTD logical devices from the FCM GUI and then, assuming you have the image on hand, replace it with an ASA logical device.
