Description	This article describes how to check the upgrade path inside of FortiOS instead of in release notes or the Upgrade path tool table.
Scope	FortiOS.
Solution	To upgrade the FortiOS, it is always recommended to follow the upgrade path tool table to avoid losing any configuration or to avoid any crash in the unit.  The Upgrade Path Tool Table: Upgrade Path Tool Table. It features the exact unit detail, current version, and expected version to upgrade. Once the data is entered, the upgrade path information is shown along with a detailed path table to follow while upgrading. It is sometimes recommended to find the information in the release notes. This path can also be found inside the FortiOS GUI under System -> Firmware -> Select Firmware. Once the firmware is selected in the GUI, two recommendations will be provided: 'Directly upgrade' and 'Follow the Upgrade Path'. Once the 'Follow the upgrade path' option is chosen, it will show the path it will automatically take while upgrading to the targeted version. Examples are shown below: It is still recommended to check the release notes for special notices regarding upgrade paths like the Recommended upgrade path from FortiOS 7.0.13 or earlier versions where if the device is running on v7.0.13 or earlier, the firewall must be upgraded to v7.0.14 first by following the recommended upgrade path before upgrading to v7.0.15 or later.
