Upgrading Remote Filtering Components

Deploying the Remote Filter Module | Web Filter & Security | v8.0.x, v8.1.x

When you upgrade Web protection solutions, you must also upgrade Remote Filtering Server by running the new installer on the machine where Remote Filtering Server is installed. See Installing Remote Filtering Server on Windows for details.


	Note Remote Filtering Server is backward compatible with the previous version of Remote Filtering Client. Although you do not have to upgrade your compatible Remote Filtering Clients, be aware that they cannot use any of the remote filtering enhancements available in the new version.

Upgrade each Remote Filtering Server instance after Filtering Service has been upgraded. If your network uses a single Remote Filtering Server, policy enforcement for remote machines is disrupted during the upgrade process. Plan for this by configuring an appropriate fail open/fail closed option. See Global remote filtering settings for details.

If you employ secondary and tertiary Remote Filtering Servers, they should be configured to communicate with the same Filtering Service as the primary Remote Filtering Server. If they communicate with different Filtering Services, failover policy enforcement occurs during the upgrade, but quota and continue time may not operate as expected.
