To learn how these facts translate into real-world benefits, read the report Upgrading to Windows Server 2019 on Dell EMC PowerEdge servers: A simple process that can dramatically reduce your storage footprint.  \nWe concluded our hands‑on testing on July 9, 2019. During testing, we determined the appropriate hardware and software configurations and applied updates as they became available. The results in this report reflect configurations that we finalized on July 7, 2019 or earlier.
