Given that the "latest firmware" is effectively frozen in time, you should plan a migration. Here are realistic replacements:
You cannot directly upload the FortiOS 6.0.17 firmware file onto a FortiGate 200D running a much older version, such as FortiOS 5.0 or 5.2. Doing so bypasses database schema modifications and configuration translations, causing database corruption, loss of firewall policies, interface misconfigurations, or a permanent boot-loop bricking the device.

Monitor your RAM usage after upgrading. The 200D has 4GB of RAM; if you run too many UTM features (Antivirus, IPS, Web Filter), you may hit "Conserve Mode."
The 200D is limited in RAM and CPU compared to newer models (like the 200F/200G), which can lead to high CPU usage when running intensive IPS or deep packet inspection features. 4. Best Practices for Maintaining 200D Performance
If you must retain the FortiGate 200D temporarily, follow this strict upgrade path from older versions:
