Relink Sensors

If you uninstall Sensor Proxy, you remove it from the communication chain between sensors and Tenable One Vulnerability Management or Tenable Security Center. Therefore, before you uninstall Sensor Proxy, you must first relink sensors directly to Tenable One Vulnerability Management or Tenable Security Center. Otherwise, the sensors cannot communicate with Tenable One Vulnerability Management or Tenable Security Center.

Note: If you are connecting to Tenable One Vulnerability Management through Tenable Nessus scanners or Tenable Agents located in mainland China, you must connect through sensor.cloud.tenablecloud.cn instead of sensor.cloud.tenable.com.

Note: Tenable Security Center 6.5 only supports Sensor Proxy linked with Tenable One Web App Scanning scanners. Tenable Nessus scanners and Tenable Agents are currently unsupported. Tenable One Vulnerability Management supports Sensor Proxy linked with all sensors except Tenable One Web App Scanning scanners.

Relink a Tenable Agent

You can relink the agent directly to Tenable One Vulnerability Management and remove Sensor Proxy from the communication chain. You do not need the Tenable One Vulnerability Management linking key.

On the agent, use the following command:
Copy
```
# nessuscli agent relink --host=sensor.cloud.tenable.com --port=443
```
The agent unlinks from Sensor Proxy and relinks to Tenable One Vulnerability Management directly.

Relink a Tenable Nessus Scanner

On the Tenable Nessus scanner, use the following command:
Copy
```
# nessuscli managed unlink
```
The scanner unlinks from Sensor Proxy.
For Tenable One Vulnerability Management, link the scanner directly as described in Link a Sensor in the Tenable One Vulnerability Management Vulnerability Management User Guide.
