Database Migration Option (DMO) and Downtime Optimization
Explains the Database Migration Option of the Software Update Manager: how one SUM run combines a software update or S/4HANA conversion with a migration to SAP HANA, the DMO variants (without system update, with system move, the move variant for S/4HANA conversion), why the source database remains a fallback, the downtime-optimized options and their constraints, and how benchmarking and repeated test cycles tune migration runtimes into a predictable cutover.
