# Update FortiGate firewall firmware

The settings in this guide are relevant for FortiOS versions 6.x and 7.x. If you have a different version of FortiOS, you can find the documentation for it in the FortiGate control panel in the top right corner or on the [official FortiGate website](https://docs.fortinet.com).

2. If you want to update only the build version for FortiOS 7, [connect to the firewall](/firewalls/fortigate/connect-to-firewall.mdx) and update the build version to the current one in the **System \*\*\*\* section**.

3. If you want to update the firmware to a new major version, [create a ticket](https://my.selectel.ru/tickets/create). In the ticket, specify:

   * the desired FortiOS version. You can see the latest version number on the [FortiGate website](https://www.fortinet.com/products/fortigate/fortios).

4. We will send in the ticket:

   * firmware files with the `.out` extension.
   * the order of loading FortiOS versions to update the operating system.
