Controlled upgrade

Controlled upgrade

Using a controlled upgrade, you can upload a new version of the FortiOS firmware to a separate partition in the FortiGate memory for later upgrade. The FortiGate unit can also be configured so that when it is rebooted, it will automatically load the new firmware (CLI only). Using this option, you can stage a number of FortiGate units to do an upgrade simultaneously to all devices using FortiManager or script.


To load the firmware for later installation – web-based manager

1. Go to System > Dashboard > Status.

2. Under System Information > Firmware Version, select Update.

3. Type the path and filename of the firmware image file, or select Browse and locate the file.

4. Deselect the Boot the New Firmware option.

5. Select OK.


To load the firmware for later installation – CLI

execute restore secondary-image {ftp | tftp | usb}

To set the FortiGate unit so that when it reboots, the new firmware is loaded, use the CLI command…

… where {primary | secondary} is the partition with the preloaded firmware.
