2. DBS3 Migration Service DBS3 to DBS3 dataset or block migration.
It has two parts:
Web interface/Restful APIs for requesting a migration, checking status or canceling a request;
Backend cherrypy plug-in server: Multi-threaded server periodically checks the database to find registered blocks for migration. The server retrieves block from the source DBS instance, check it against the destination instance, then insert into destination if it does not exist yet.
