Cisco FTD 1120 hardware firmware change from FTD to ASA

Hi all

Thanks for reading this message.

I know for sure that FTD 1120 can run ASA firmware as we have got the running in our network.

I have been trying to install one of the FTD1120 with ASA for almost the whole day and it has been proving very difficult. The FTD is currently connected to a console server and I do not have physical access to the box.

Unfortunately FTD are not the most user friendly hardware/firmware.

Please guide

Thanks

@Zaaf Aba have you followed the steps in the reimaging guides? where are you currently stuck?

Thanks Rob for the reply. Just saw your reply.

After spending hours and hours I manage to fix similar issue on FTD 1120

Important points to note is that each FTD series 1000, 1100, 1200, 2100 , 3100, 4200 has different upgrade or reimage methods.

For FTD 1120 I followed

via console after login I used to following commands:

connect ftd
configure network ipv4 manual 192.168.13.8 255.255.255.0 192.168.13.1
configure network ipv4 dhcp-server-disable
exit
firepower# scope firmware
download image tftp://192.168.22.10/cisco-asa-fp1k.9.16.A.B.SPA
show download-task
scope auto-install
# remember to NOT type full file name, just need the version number.
install security-pack version 9.16.A.B

FTD rebooted after the install

I then copied the ASA firmware and ASDM to disk0 again, so that the file is visible instead of hidden somewhere with in FTD/ASA
TEST-FW(config)# boot system disk0:/cisco-asa-fp1k.9.16.A.B.SPA

This syntax is also valid:

download image usbA:cisco-asa-fp1k.9.16.A.B.SPA
