Cloud connector doesn't require a database but there are a few steps if you're planning to move to a new server.

If you're planning to install on a new server, ensure you can reach AWCM which is usually installed on your Device Server on https://servernameorip:2001/awcm/status (you should be able to see a "OK")

On your AirWatch Console go to Groups & Settings> All Settings>System> Enterprise Integration>Cloud Connector.

Download the cloud connector and install on the desired server. To test, go back to Groups & Settings> All Settings>System> Enterprise Integration>Cloud Connector and click "Test connection" your server and IP should show there. If it doesn't show. Check the Cloud connector server C:\VMware\AirWatch\Logs\CloudConnector.log it should show why it failed.
