Description
Learn how to fix FortiGate 7.4.2 License Issues, verify license status, and avoid common firmware upgrade and downgrade mistakes.
Scope
If you manage a firewall, you must understand recent licensing changes. From version 7.4.2 and above, a valid FortiGate license is required for successful firmware upgrade.
Scope: FortiGate devices running FortiOS v7.4.2 and above, ensuring smooth and reliable performance.
How to Check FortiGate License Status
You can easily verify the license status using the CLI command below for smooth and accurate checking.
Solution
Why a FortiGate License Is Required
Starting with FortiOS v7.4.2, Fortinet requires an active and valid support license to smoothly perform firmware upgrades.
As a result, devices without a valid contract may face potential FortiGate 7.4.2 License Issues and cannot install newer firmware versions. This important change ensures proper support, enhanced security updates, and controlled access to firmware releases.
diagnose test update info contract
This command shows whether your device has a valid support contract.
Understanding Inactive License Output
If the license is inactive, the output will clearly show similar results, indicating a potential issue.
Support contract: pending_registration=0 got_contract_info=0
account_id=[] company=[] industry=[]
Contract=AVDB-2-20-19700101*NIDS-2-20-19700101
No contract information.
No contract information.
No user ID.
What These Fields Mean
- pending_registration=0 → Device is not waiting for registration
- got_contract_info=0 → No contract information retrieved
- account_id=[] → No Fortinet account linked
- company=[] → No company registered
- industry=[] → Industry field is empty
- Contract line → Shows default or expired service placeholders (not active)
- No user ID → No registered user associated
⇒ Therefore, this clearly confirms that no active license is present, and firmware upgrades will unfortunately fail.
Understanding Active License Output
In contrast, an active license will display:
- Account ID
- Company name
- Contract details
- User ID
Originally, in FortiGate 7.4.2 License Issues, this is clearly shown in a GUI screenshot in FortiGate, where all important license details are visible and missing ones are highlighted.
⇒ If these details appear, your device is properly licensed and confidently ready for firmware upgrades.
Firmware Upgrade Restriction Rule
License timing directly positively affects upgrade eligibility, while delays may negatively impact access.
- If the license expiration date is earlier than the firmware’s first GA (General Availability) release date
→ Upgrade to that firmware version will be blocked - If the license is still valid at the time of release
→ Upgrade will be allowed
This important rule ensures that only properly supported devices receive new firmware version, while unsupported ones are restricted.
Firmware Downgrade Behavior
Downgrades follow a different rule.
- Downgrading between major versions is not restricted
- This is because older firmware versions may still fall within the license validity period
⇒ So, even without a valid license, FortiGate 7.4.2 License Issues may occur, but downgrades may still work.
What Happens If the License Expires
If your license expires:
- Firmware upgrades will stop working
- Access to newer versions will be restricted
In that case, you should:
- Contact your Fortinet sales representative
- Reach out to an authorized partner
- Renew your support contract
