You simply cannot restore configurations between different hardware models. Depending on the complexity of your config, either rebuild from scratch (which has many advantages), or re-format config file manually (port names, model-specific lines etc.) which is not a trivial task. More or less it's the same amount of work.

Third alternative: the FortiConverter converts between FG models. But...it's not for free. Maybe your Fortinet partner owns one and can offer you the conversion.

Another key issue you need to be aware of is the difference of the OS version. If possible you should bring up the version on the existing machine to match the new one. Sometimes it might not be possible.

We needed to take similar steps in the past when Fortinet discontinued one hardware model we were using and when we decided to upgrade the hardware.

How we did was:

1) configured & tested the key features we deploy such as IPSec and SSL VPNs, FW policies, routing protocols including interface config with the new hardware to see the config difference in CLI.

2) come up with formulas how we need to adjust the config.

3) then start copying&pasting config with the modifications section by section

4) then our case we repeated it for all VDOMs.

How to cut it over to the new one needed a different type of planing and preparation.
