In preparation for the second runs of the ProtoDUNE detectors at CERN (NP02 and NP04), DUNE has established a new data pipeline for bringing the data from the EHN-1 experimental hall at CERN to primary tape storage at Fermilab and CERN, and then spreading it out to a distributed disk data store at many locations around the world. This system includes a new Ingest Daemon and a new Declaration Daemon. The Rucio replica catalog, and FTS3 transport are used to transport all files. All file metadata is declared to the new MetaCat metadata service. All of these new components have been successfully
tested at a scale equal to the expected output of the detector data acquisition system (~2-4 GB/s), and the expected network bandwidth out of the experimental hall. We present the procedure that was used to test and the results of the test.
