RQMCopyUtility - correct URL

I have this, it starts, but does not actually do anything so wondering if there is something wrong here with the information - copying from one server to another (source is 5.0.2)

java -jar RQMCopyUtility.jar -s=https:/{servername}:9443/qm/secure/service/com.ibm.qm.integration.service.IIntegrationService/resources/{projectname} -us={username} -pws={password} -d=https://{servername}:9443/qm/{projectname} -artifactType=testplan -artifactId=600 -i=remotescript -l=importlog.txt -force

Because the assets are so big, I need to copy individually by the UUID of the test plan e.g. the 600

Thanks in advance for any help
