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.

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.
