When "migrateIn" is done, the following error is sometimes outputted in ssg.log. 
SEVERE 127 org.hibernate.util.JDBCExceptionReporter: Duplicate entry 'com.l7tech.external.assertions.apiportalintegration.server.Porta' for key 'i_classname_name' 

The "migrateIn" succeeds. 
It seems there is no problem in the operation. 
However, the message is "SEVERE".
