Hi,

You want to know how to upgrade a ADOM in FMG from a earlier version to a newer one while FMG is in offline mode ?

Hi @sleepingzzz ,

The offline mode of ADOM is just to prevent you from connecting to the managed devices.  So it will not impact you for upgrading the ADOM.

It is still the same way for ADOM upgrade in Offline Mode.

Hi. Sorry what I am trying to ask is does upgrading ADOM need the FMG to be connected to Internet? The setup that I have is an air-gapped environment. 

Also, does it need to upload any image file to upgrade the ADOM?

Thanks!

No for both.
