We not able to start dtserver due to error in the log that no space available in the device. But looks space available in the host. Meanwhile resolving the issues, we planned to move the dynatrace server to another host. As we not able to start dtserver, we may not able to de-activate the existing license through dtclient. When try to de-activate through eservices, it is asking for de-activation & activation key. How can we get dtactivation key & activation key for that license. Is there any file available in the server to get those details?
