EUROFOS, Fos-sur-Mer, the largest container terminal in France, did a major NAVIS N4 upgrade from 2.6 to 3.6. DSP supported the terminal during this upgrade project, providing field development to synchronise data and events from their testing 3.6 environment to the 2.6 production during 3 major dry runs. This helped to identify potential issues prior to the go-live.
