Upgrading to a New Version - Main Release

The procedure for upgrading to a new version of the Web Gateway appliance software that is provided as a main release differs depending on the version that you are currently running.

Create a configuration backup before you upgrade and be sure to save it in an external location, so it is still available in case you cannot access Web Gateway after the upgrade failed.

  • 7.3.x or later — Upgrade to the new version from the Web Gateway interface or from a system console.
  • 7.2.x or earlier 7.x, 6.9.x, or 6.8.x — Reimage the appliance using an image of the new version.

Upgrade from the interface

To upgrade to a new version from the Web Gateway interface, select an appliance and perform the upgrade, then restart the appliance.

  1. Select Configuration | Appliances.
  2. On the appliances tree, select the appliance where you want to perform the upgrade.
    The appliance toolbar appears on the upper right of the tab.
  3. Click Update Appliance Software.
    The upgrade starts, and you are logged off from the interface.

    When the upgrade is complete, a message informs you about the completion.

    If you are running Web Gateway as an appliance on a virtual machine, a warning also appears on the host system where you created the virtual machine. You are warned that an operating system is being used that is not recommended.

    To optimize the operation of the virtual machine, adapt its settings by configuring the recommended operating system, which is CentOS, 64 bit, version 7.
  4. To perform the restart of the appliance that is required:
    1. Log on to the interface again.
    2. Select Configuration | Appliances, then select your appliance.
    3. On the appliance toolbar, click Reboot.

When the restart is complete, you can again log on to the interface and start working with the new version.

Upgrade from a system console

When upgrading to a new version from a system console, you can work with a local system console or remotely using SSH.

When working with SSH, consider using a terminal multiplexer to ensure that the upgrade will not fail due to an unstable or broken SSH connection.

You can use the tmux multiplexer that Web Gateway has installed.

  1. Log on to the appliance where you want to perform the upgrade.
  2. Run the following commands:

    yum upgrade yum

    yum upgrade


    When the upgrade is complete, a message informs you about the completion.

    If you are running Web Gateway as an appliance on a virtual machine, a warning also appears on the host system where you created the virtual machine. You are warned that an operating system is being used that is not recommended.

    To optimize the operation of the virtual machine, adapt its settings by configuring the recommended operating system, which is CentOS, 64 bit, version 7.
  3. To perform the restart of the appliance that is required, run this command:

    reboot

When the restart is complete, a logon prompt appears. You can now log on to the Web Gateway interface and start working with the new version.
