Just getting started with FWSM. IT is currently running version 2.3(4) with device manager 4.1(5). Is it ok to move up to version 4.X?
If so note for version 4.X say you need to be at maintenance software Release 2.1(2)or higher. It appears that 2.1(4) is latest. Do you update this first and the the image followed by the device manager? It says to check maintenance software you must boot into the maintenance partition. There isn't another way to check that I assume?
