Since the DMO works only with ABAP systems, a dual-stack split may be required beforehand.

If a dual-stack split is necessary, make sure that it has already been performed before you start the update and migration procedure.

For more information about the dual-stack split, see the section Dual-Stack Split in the Upgrade Master Guide for your SAP NetWeaver version. For detailed information about the dual-stack split and its procedure using Software Provisioning Manager, see also the Dual-Stack Split Guide. All guides are mentioned in section Other Required Documentation.
