You can increase number of threads to import data faster. Open DataMigrationUtility.exe.config file located in same folder SDK\Tools\ConfigurationMigration. Search for “numberofinputthreads” and change value from 5 to 20 or more based on requirement. Once updated tool will initialize 20 threads and data will be imported comparatively faster.
