The call is not reaching TSPS and is failing because of a certificate issue
javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
The recommendation is to import the custom/or self-signed certificate into the truesightpserver/modules/jre directory and verify that the JAVA home variable is set properly.
Sometimes we see that the cmapolicymigration.bat does not export any policy and there are no output errors in the datamigration.log. When that happens, the likely culprit is the TS certificates.
If you have added any custom certificates or certificates which are modified in loginvault.ks then the same should be imported in the JRE cacerts (truesightpserver/modules/jre)
The custom certificates need to be imported into loginvault.ks, pnjserver.ks and cacerts on Both TSIM and TSPS servers. There should be a minimum of 3 certificates - root, intermediateCA and truesightserver, as documented here
You should be able to use the keytool list command that is documented to see what is missing and then move forward from there and according to the documentation.
