Important Notes:
The Manager software version 10.1.7.50 and above supports only TLS 1.2 ciphers for Manager and Sensor communication.
Caution
If you are currently using Sensor software version that supports TLS 1.0 and you upgrade your Manager to any software version that supports only TLS 1.2, the communication between the Manager and Sensor will fail. Therefore, you must first upgrade the Sensor to a software version that supports TLS 1.2 and later upgrade your Manager to the desired version. Post this, you may upgrade the Sensor to any later version as per your requirement. Refer to KB96194 for more information.
The Trellix IPS 11.1 release is applicable to the Central Manager, Manager, NS-series Sensors and Virtual IPS Sensors.
As with any upgrade, Trellix strongly recommends that you always first try the upgrade in a test environment.
The current version of 11.1 Manager software can be used to configure and manage the following:
NS-series Sensors on 10.1, and 11.1 software
Virtual IPS Sensors on 10.1, and 11.1 software
NTBA Appliances (physical and virtual) on 9.1 software
The upgrade involves the following phases that you must complete in the same order:
If applicable, Trellix IPS Central Manager upgrade.
Trellix IPS Manager upgrade.
NS-series Sensor software or Virtual IPS Sensor software upgrade.
Important
You must disconnect any M-series Sensors configured in the 10.1 Manager before upgrading to 11.1 Manager.
You will require the Trellix Intrusion Prevention System 11.1 Product Guide during the upgrade process.
It is also strongly recommended that you read the Release Notes for the associated product before you upgrade because this document makes references to several new features and enhancements.
