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.
