Fortigate firewall migration

I have a legacy Fortigate model 400A want to be replaced by a 300C model. The existing 400A model is running a very old firmware v3.0, but the 300C is v5.0. Can you guys please give me some suggestion how to do the migrate? I'm not really familiar with forti products...

Many Thanks

It is best to engage fortinet to guide the specific steps since this should be part of the maintenance and do have them advise the details - they have a portal for user like yourself (http://www.fortinet.com/migrating_to_a_fortigate_firewall.html)

In EE forum there is sharing that you may want to check out - the author also gotten it from the principal support
https://www.experts-exchange.com/questions/26929154/Copy-Configuration-between-different-Fortigate-Models.html

of course in their kb, ther have some in general like this - Technical Tip : How to load/convert a FortiGate configuration file from one unit to another (file conversion for a different model).
