Step 3: OS Migration
USB Image
The file FNAC_XX0C-v7-buildxxxx-FORTINET.usb is a bootable software image that can be installed onto a USB flash drive. This is image contains copies of the FortiNAC-OS and FortiBootLoader which are written to the target system, replacing the existing CentOS installation.
USB Flash Drive Installation
On a Linux system do the following:
-
Insert a USB flash drive into an available USB port. This drive will be completely overwritten, so it should not contain any valuable data. The size should be at least 2GB.
-
Check to see if the drive was automatically mounted and unmount it. Determine the raw device for this drive and remember it. Going forward we will refer to the device “/dev/sda”, but it may vary from system to system.
-
Install the image FNAC_XX0C-v7-buildxxxx-FORTINET.usb onto the USB flash drive with the command:
sudo dd if=FNAC_XX0C-v7-build0402-FORTINET.usb of=/dev/sda
-
Remove the USB flash drive from this system.
Note: If you only have a Windows system, try balenaEtcher instead of “dd” to perform the USB flash drive installation.
