Step 1: Upgrading FortiGates
You can upgrade all firewalls at once or perform batch upgrade for selected firewalls.
To upgrade all FortiGates from FortiManager:
- Log on to FortiManager.
- Go to Device Manager > Firmware.
- Select all the FortiGate devices and click Upgrade.
- In the Upgrade Firmware dialog, go to the Upgrade to drop-down. Choose the firmware from the FortiGuard Images. Click OK.
FortiManager downloads the firmware image from FortiGuard server and upgrades the selected FortiGate devices. The Upgrade Firmware Task dialog shows the progress of the upgrade.
- Click Close after the upgrade is complete.
After each FortiGate device is upgraded to 5.6, FortiManager will automatically add a revision into revision history through auto-update. The upgraded FortiGate devices are visible in Device Manager.
