Configuration compatibility between models

I have a FortiWifi 30E that runs FortiOS 6.2.17 which it seems it came to its EOL and support wont be continued.
The plan is to upgrade to a FortiGate 40F or a FortiGate 50G.
The configuration file from the 30E can be restored with no problems on the 40F/50G or are there extra steps to take in consideration for this change?
