Downloading and Installing the Upgrade

To upgrade your appliance:

1. In the browser-based management tool, click System > Actions > Update Clone > Update Clone.

2. When the update is complete, click the Upgrade tab.

3. Check Enable Download > type the URL for the upgrade.

   The URL is available from your appliance vendor.

4. Click the Download Time drop-down list > select the time you want the download to occur.

5. Check Enable Install.

6. Click the Install Time drop-down list > select the time you want the upgrade to be installed.

7. Click Apply.

8. As soon as possible after the upgrade is installed, update the appliance's clone image by clicking System > Actions > Update Clones.

   This is necessary to avoid the appliance automatically applying an earlier clone image which could make the proxy server unstable.
