Firepower/ASA/FXOS code versions

[nevin.maurice1]

I need some confirmations about code versions.  Maybe someone can provide confirmation for me on the following:  We have a mixed environment at this time with:

- Cisco ASA devices running ASA code

- Cisco ASA devices running ASA code and SFR(firepower services module) firepower code

- Cisco ASA devices that have been converted to FTD image running firepower code

- Cisco FTD devices (4100, 2100) running FXOS and Firepower code

Updating Code Process:

- ASA devices > update ASA code

- ASA devices with SFR > update ASA code and Firepower code (compatible versions)

- ASA devices converted to FTD > update only Firepower code (no underlying OS or FXOS to worry about)

- Cisco FTD Device 2100 > update only Firepower code as FXOS is updated as part of it

- Cisco FTD Device 4100 > update FXOS and Firepower code (compatible versions)

Does that sound correct?

Hi

Your upgrade processes are ok.

Take a look on this link, it explains what you just said:
