Security Update Support After Firmware License Expiration on Fortigate
Dear Team,
In the article "Prevent firmware upgrade depending on the current firmware license's expiration date" (7.4.2), it states that "In FortiOS 7.4.2 and above, enforcement of an active FortiGate firmware license to allow firmware upgrades has been improved. Enforcement is based on the expiry date of the current firmware license compared to the release date of the first GA release of a major version. For example, for FortiOS 7.4.x firmware upgrades, enforcement is based on the expiry date of the current support contract compared to the release date of FortiOS 7.4.0 GA."
This means the FortiOS license expiration date must be later than the "first GA release" of a major version (e.g., 7.2.0, 7.4.0, 7.6.0, etc.). For instance, if the current FortiOS license expires on February 1, 2025, and the version is 7.2.x, it can be upgraded to 7.4.x because the 7.4.0 GA release date was May 11, 2023. It can also be upgraded to 7.6.x because the 7.4.0 GA release date was July 25, 2024.
Further assuming the 7.8.0 GA release date is May 25, 2025, a system with an expiration date of February 1, 2025, would not be able to upgrade to 7.8.0.
Is my understanding correct?------>First Question
Furthermore, the document "Prevent FortiGates with an expired support contract from upgrading to a major or minor firmware release" (7.4.0) states that "If the FortiGate support contract has expired, you will be unable to upgrade the firmware to a higher major version, such as from FortiOS 7.0 to 8.0, or to a higher minor version, such as from FortiOS 7.4 to 7.6. However, you can upgrade the firmware of a FortiGate with an expired support contract to a higher patch build, such as from FortiOS 7.4.0 to 7.4.1, to allow for security updates."
This means that once I can upgrade to a specific GA release, I can still receive support for minor versions and patch releases even if the firmware license expires later.
Is this understanding correct?---->Second Question
Finally, based on the above assumptions,I can only upgrade to 7.6.x, and the firmware license has expired.
Does this mean that security patches will be available for 7.6.x until the End of Support (EOS) date (2029-01-25)? Or is security patching only supported until the End of Extended Support (EOES) date? --->Third Quesion
