Upgrading AsyncOS for Web uses the following two step process:

1. Configure the update and upgrade settings. You can configure settings that affect how the

Web Security appliance downloads the upgrade information. For example, you can
choose from where to download the upgrade images and more. For more information, see
“Configuring Upgrade and Service Update Settings” on page 539.

2. Upgrade the system software. After you configure the update and upgrade settings,

Consider the following guidelines when you upgrade AsyncOS for Web:

• Before you start the upgrade, save the XML configuration file off the Web Security

appliance from the System Administration > Configuration File page or by using the

saveconfig

command. For more information, see “Managing the Appliance

• When upgrading, do not pause for long amounts of time at the various prompts. If the TCP

session times out during the download, the upgrade may fail.

• Consider saving the configuration information to an XML file after the upgrade completes,

too.
