Firesight Upgrade from 6.2.2 to 6.2.3 failed

[priyank.patel]

FMC 750 was running on 6.2.2 version and when we tried to upgrade it to latest version 6.2.3 it failed.

The ping was working fine but we are not able to access the FMC GUI. We tried to reboot the device, no luck.

Then we tried to restore the image via physical connection to firepower console but it gives error.

Possible solution to restore the firepower console without any traffic interruption.

What error do you receive via the console?

My suggestion would be to open a TAC case to resolve this, especially if this is in production.
