While specific build numbers change (e.g., 6.0.12, 6.0.13), the general rule for the FortiGate 200D is:
Despite its age, the 200D remains a capable device for lab environments or basic internal segmentation.

However, Fortinet often releases "minor" versions and "maintenance" builds. The most stable and final iterations generally fell into these categories: While specific build numbers change (e
If you are still running a very old version (e.g., v5.0), you cannot jump directly to 6.0.17. You must follow a multi-step path (e.g., 5.0 -> 5.2.9 -> 5.4.10 -> 5.6.11 -> 6.0.17) to prevent configuration loss. Replacement Models: Fortinet recommends migrating to the FortiGate 200E (which is also older) or current generation models like the FortiGate 200F for continued support and modern throughput. Hardware Disposal: For devices past their End of Service Life (EOSL) , ensure you perform a execute factory reset via CLI to wipe sensitive data before decommissioning.

Since you cannot safely run the latest firmware (because there is none), the only responsible action is to . Fortinet offers several natural successor models. Here is a comparison:
Note: You must check the Fortinet Support Site (FortiGuard) for the specific "build" number. For example, v6.0.14 might have been the final signed release for the D-series.
To summarize clearly: That version is now over two years old and has multiple known, exploitable vulnerabilities that will never be fixed.
