For upgrading from, or, see the Upgrade Guide for RSA NetWitness Platform This guide applies to both physical and virtual hosts (including AWS and Azure Public Cloud).

Running in Mixed Mode

Running in mixed mode occurs when some services are upgraded to the latest version and some services are on older versions. See "Running in Mixed Mode" in the RSA NetWitness Platform Hosts and Services Getting Started Guide for further information.

Note: If you are running Endpoint Log Hybrid in mixed mode, make sure Endpoint Broker is on the same version as one of the Endpoint Servers.

Upgrade Considerations for ESA Hosts

Mixed mode is not supported for ESA hosts in NetWitness Platform version 11.5 and later.

IMPORTANT: The NetWitness server, ESA primary host, and ESA secondary host must all be on the same NetWitness Platform version.

Upgrade Considerations for ESA Analytics

The Event Stream Analytics Server (ESA Analytics) service is not supported or available in NetWitness Platform version 11.5 and later. The Whois Lookup Configuration and ESA Analytics Mapping panels are no longer in the user interface ( (Admin) > System).

Note: Event Stream Analysis (ESA) is not end of life. ESA Correlation rules and the ESA Correlation service are supported. ESA Analytics, which is used for Automated Threat Detection, is different from ESA Correlation Rules and is EOL. In its place, you can use ESA Correlation as is offers more functional capabilities and better performance.

Upgrade Considerations for STIX Custom Feeds

The custom feeds created before version 11.5 are processed automatically. On upgrade, the data sources created for ADHOC, REST and TAXII server and the feeds are pulled automatically. See "Create a STIX Custom Feed" in the RSA NetWitness Platform Live Service Management Guide and "Configure STIX as a Data Source" in the RSA NetWitness Platform Context Hub Configuration Guide for further information.

Change to Column Groups in the Events View

To improve consistency when loading results in the Events view, the number of columns in a column group is limited to 40.

If you are upgrading from version or later, after you upgrade to, column groups migrated to the Events view from the Legacy Events view still function with more than 40 columns. However, when you edit those groups, you receive a warning that tells you to reduce the number of columns below the limit of 40 columns.

Upgrade or install Windows Legacy Collection

Refer to the Windows Legacy Collection Guide for RSA NetWitness 11.x (

Note: After you update or install Windows Legacy Collection, reboot the system to ensure that Log Collection functions correctly.
