NW 7.5 is only UC: no non-UC kernel (and no non-UC export load) available.😕 Yes, in general DMO may include the UC Conversion – but not for target NW 7.5:.For SAP R/3 4.7 and SAP ECC 5.0 Unicode systems: these releases do not include the Customer-Vendor-integration (with Business Partners) that is required for SAP S/4HANA, so a two-step approach is required.If the source system is not yet on UC, the transition is a two-step procedure.If the source system is already on UC, the transition is a one-step procedure.Source system has to be Unicode, and an ABAP single stack.SAP ECC 6.0 (with or without enhancement packages) is required as source release version.

SAP Readiness Check is technically not required before starting the SUM – nevertheless it is highly recommended.Simplification Item checks have to be executed beforehand, and all issues have to be solved, as the SUM will execute the same checks, and will stop in case of open issues.Maintenance Planner has to be used beforehand to check the system and to provide the stack.xml for the SUM (as well as to provide the required software archives).The data conversion is partly triggered by the SUM, partly an activity after the SUM run (for FIN and ML data: IMG activities). Data Conversion: conversion of table content to new data model.Database Migration (if source system is based on non-HANA database): migrate existing database content to SAP HANA database (using Database Migration Option DMO of SUM).Software Update: Provide new applications & new tables (as part of the new data model) by providing new software components (like S4CORE) & updating existing software components.System Conversion: three tasks for SUM to enable Simplification of SAP S/4HANA

Software Update Manager (SUM) is the tool for this transition.
