How to transfer configurations from Fotigate 100a to Fortigate 100d

Hi,

I have an old fortigate 100a which is running fine. Recently we bought a new fortigate 100d.

I would appreciate if anyone can tell me how do i transfer the configurations that is already in the old fortigate 100a to the new fotigate 100d.

I do not wish to manually configure the firewall policies on the new Fortigate 100d.

Many Thanks

You should be able to do a backup of the image and then restore to new device

Hi,

DO NOT backup the firmware from the 100a and push it down the 100d it will cause issues. The only way to do it is to use the FortiConverter or to call support and ask them to do it internally for you.

If you backup the 100a and push it down the 100d make sure that they are on the same firmware. and modify the first line on top of the config file.

The fortigate 100A has DMZ1 and 2 but the 100D only has a single DMZ port. If you were actively using DMZ2 to, you’d need to rename any instances in the config to that of another port.

Once the ports are correct, you have to change the first line in the config to match the correct model. If the model doesn’t match, it will reject the config every time.

#config-version=FG100A-4.00-FW-build113-091202:opmode=0:vdom=0:user=admin
…or something similar would be changed to…
#config-version=FG100D-4.00-FW-build113-091202:opmode=0:vdom=0:user=admin

If you’re not sure of the model number prefix on a Fortigate, just export the config from the destination device and look at that first line.

Save the modified config and you should be able to import it to the new device via the GUI, or via the CLI using the “exec restore config …” command.

There could possibly be a few errors once the firewall reboots, so be sure to check via the CLI with “diagnose debug config-error-log read”. A lot of times the errors are irrelevant (something the old device had that the new one doesn’t) but pay attention for anything that could be important.

The next time you reboot the device, those errors should be gone as they were parameters or values that couldn’t be applied to the new device.

At this point the new device should be functioning like the old one–but much faster.
