Upgrading to a new version provided as a 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. Note: 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. Download an image of the new version from the download page of the McAfee Content & Cloud Security Portal at https://contentsecurity.mcafee.com/software_mwg7_download. 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. 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.
