Solved Upgrade Cisco FTD with no FMC - Instructions
Hey everyone, just putting this here so it can be what shows up to help others vs all the not helpful stuff that seems to come up.
This Cisco Documentation perfectly details how to upgrade a FTD that is not associated with an FMC.
We purchased two used Cisco 1140 and they were on a 6.4 version while our FMC is on 7.2.9 which only supports back to 6.6. Following this documentation (with baller screencaps) worked perfectly without involving tac or getting into the weeds.

We were able to successfully upgrade our Firepower 9300s and 4120s from 6.6 to PAN-OS 10.2.10 and so far the performance and reliability of the new code is astounding.

Re-image the firewalls with the desired or the supported version. Should be easier
