Firepower 4110 and FXOS version

[nevin.maurice1]

My Firepower current FXOS version is 2.2.2(28), just recently updated.  Want to apply Firepower 6.2.3 on the device, however Cisco compatibility matrix indicates I need 2.3 FXOS.  Is this absolutely required?  Every time we try to update FXOS we run into hardware problems...some are know bugs, some are not. Each time TAC has to get involved.  We just updated to 2.2.2.28 and had issues with 2 of our 4 devices (4110).  We are hesitant to update FXOS again at this time, but want to get all of our Firepower code at 6.2.3.  

Any thoughts/recommendations?  Do we need to update FXOS?

Obviously this will not help me, but let me get this please: if you run FXOS how come you also use Firepower?
You mean Firepower for the management server and FXOS for the security appliances?

@Florin Barhala FX-OS is for the physical chassis, not the logical device.

The logical device in this case runs a release of Firepower Threat Defense software (and the managing FMC runs a compatible release).
