6. New DCS cluster The 'old' DCS cluster has been fully upgraded and patched, detectors are invited to test functionality (several already did, and no major issues were reported) The 'new' DCS cluster is from 75% physically installed and currently being cabled with power and network. First machines shall be available for detectors for migration by the end of the week 12/1/12Shutdown progress and planning A.Tauro 6 Andre’
