Firepower Management Center 750 upgrade version from 6.2.3 to Latest

[arumugasamy]

I need to upgrade the FMC 750 from the current 6.2.3 to the latest supported image.

The upgrade guide shows that the direct upgrade supported is version 6.4.0.16.

Please give me your expert suggestion & plan for the above. If it is supported by the 6.4.0.16 upgrade then is it support the 7. x version? Also, pls provide the Hardware compatibility for the above upgrade (6.4.0.16 > 7. X)

@arumugasamy you are correct 6.4 is the last supported version for the FMC 750 hardware.

If you wish to use FMC 7.x you will need to purchase new FMC hardware or the FMC virtual appliance.
