Upgrade

This section the following ways to upgrade FortiIsolator firmware:

• Upgrade the firmware by GUI (Web and USB)

• Upgrade the firmware by CLI

In High Availability mode, upgrading one FortiIsolator appliance or VM automatically batch upgrades all FortiIsolator appliances or VMs in the cluster. Each appliance or VM automatically reboots after it gets upgraded. The appliance or VM that triggers the batch upgrade is upgraded last. The reboot might take a few minutes.

To upgrade the firmware by web

This feature applies to both FortiIsolator hardware appliances and FortiIsolator VMs.

1. Log into the FortiIsolator GUI as the admin administrative user.
2. Go to System > Upgrade.
3. Under Upgrade by Web, click Choose File and locate the previously downloaded firmware image file. See Upgrade information for instructions about downloading the upgrade firmware.
4. Under Start Hour, select the hour when FortiIsolator starts the upgrade process. Selecting immediate triggers the upgrade immediately.
5. Click Submit to upgrade the firmware.

The FortiIsolator unit backs up the current configuration, upgrades to the new firmware version, restarts it, and restores the backed up configuration. This process takes a few minutes.

To upgrade the firmware by USB device

This feature only applies to FortiIsolator hardware appliances, such as FortiIsolator 1000F.

1. Log into the FortiIsolator GUI as the admin administrative user.
2. Go to System > Upgrade.
3. Under Upgrade by USB, click Click here and locate the previously downloaded firmware image file that stored in USB device.
4. Click Submit to upgrade the firmware.

To upgrade the firmware in CLI

This feature applies to both FortiIsolator hardware appliances and FortiIsolator VMs.

1. Log into the FortiIsolator CLI as the admin administrative user.
2. Run the following command to install the firmware image from a server:

   system-upgrade {tftp|ftp} <path> <server> [:<port>] [<user>:<password>]

   For FortiIsolator hardware appliances, you can also install the firmware image from a USB device that contains the previously downloaded firmware image by inserting the USB and running the system-upgrade command.

The FortiIsolator unit copies the new firmware image from the server or USB device to local hard disk, backs up the current configuration, and performs upgrade to the new firmware version. This process takes a few minutes. After the upgrade, the system reboots and deletes the firmware image from local disk.
