Need help upgrading!

[Expediationtech]

I have the Fortigate-81E-POE. I am trying to upgrade from 7.4.2F to 7.4.4F I have to follow the update path from 7.4.2F to 7.4.3F first but it wont let me upgrade. When attempting to upgrade to 7.4.3F, the following error message is displayed:

This is a FortiOS v7.4.3-build2573 firmware image that cannot be installed because the device's FortiGuard license for firmware upgrades expired on 2017/07/07.

Any suggestions thanks!

Hi @Expediationtech 

I think you need a license. Please check the document below about prevention when upgrading.
