Firepower sensor upgrade.

mdieken011 — Fri, 21 Feb 2020 15:26:55 GMT

I have 5525x ASA's in a HA pair. When they went into production we didn't have the licenses for the Firepower sensors. The firepower version they are currently running is 5.4. I would like to upgrade them to 6.2.2 or the latest version. The policy map is not directing traffic to the module at this time. Can I just copy up the asafr-5500x-boot-622-3.img file and then do a recovery? I can't have down time unless it is scheduled. Just looking for the best path to take for the upgrade. My Firepower Management Center is running 6.2.2.1. Thanks in advance!

Hello mdieken011,
If you are comfortable with re-imaging the SFR Module, then that would be the best path, since currently the FMC and the SFR Module are in incompatible versions anyway.
The link below has the procedure to re-image.

I believe there is a portion were it asks to reload the ASA, that is not necessary. I have performed the re-image without reloading.

Please also ensure to check the compatibility version between your ASA and the SFR module.

Keep in mind that you need two files, the boot file and the actual package that is used once you boot into the SFR to install the software.

Please review the information above.

Thanks Argrullo! The devices are in production so I wanted to make sure I understood the steps involved in the upgrade. I thought that is what would be involved but am careful.
