The system was examined in the periodical simulation mass production campaigns run since the last year and was improved according to constructive feedback. In parallel, the data transfer challenges were performed with the transpacific and transatlantic network which plays an essential role in success of the Belle II experiment in the next decade 000000511 8560_ $$fkooktae.kim@desy.de 000000511 8564_ $$uhttps://docs.belle2.org/record/511/files/BELLE2-CONF-PROC-2017-008.pdf
