You do not need a conversion tool in order to do NAT. Look at each NAT and apply it a central-NAT or per-policy as required. The concept are equally the same between ciscoASA and FortiOS

Thank of central net the same as ciscoASA, Palo,Juniper,CHKP,Forcepoint NAT-tables. YMMV but both are equally beneficial and easy concepts to figure out. Ken Felix
depending on when you bought the FortiGate FortiConverter is a free service.
but if that isn't an option then you best understand what the ASA does very well. then it is not that hard to configure the FortiGate in a similar way if you understand FortiGate also. if there is an issue with understanding one of them look for assistance, that will probably also come with a price.
unfortunately i now see it is a purchased service also, probably cheaper then the forticonverter license, which is quite affordable and probably easier to purchase when you buy the equipment then later.
You can download the forticonverter python based free tool from support site. (Download > Product=Foriconverter > Download: / FortiConverter/ v5.00/ 5.6/ 5.6.2/ FortiConverterSetup_5.6.2_Build0541.py.exe).
I used a few weeks ago and it was easy peasy...
the new (python) version is not free, both the legacy and new version require a license (which is shared between both).
from the release notes:
For all 3rd party conversions, you can complete a conversion and view the results in the tuning page. All other functionality is disabled until you upload the full license. In most cases, this limited functionality is sufficient to allow you to evaluate the product.
