You can upgrade the standalone Virtual IPS Sensors with the new AMI for the Sensor. To upgrade the Virtual IPS Sensors, you should launch new instances of the Sensor with the new AMI and user data. The old instance of the Sensor should be deleted. The environment after an upgrade of the Virtual IPS Sensors can be as follows:
- For standalone Virtual IPS Sensor, launch a new Sensor instance with the latest software version along the new user data so that the Sensors are deployed in the existing cluster. Terminate the Sensor with the older software versions. Signature set upgrade fails for the vIPS Cluster till the older Sensor versions are terminated.
- You can create a new vIPS Cluster with the new Virtual IPS Sensor AMI and user data with the latest Sensor software version.
- All Sensors in a cluster should be upgraded to the same Sensor software version for configuration update from the Manager to be successful.
- If you upgrade the Manager to the latest Manager software version, the Virtual IPS Sensors have to be upgraded to the latest Sensor software version as well.
