You are performing an SAP S/4HANA conversion with DMO as an inplace migration. How does SUM transfer the data by default from the source database to the target database during the migration?

Question

Options

• AUsing R3load and memory pipes
• BUsing work processes and network socket connection
• CUsing R3load and file transfer
• DUsing R3load and network socket connection

• A
  92% (24)
• C
  4% (1)
• D
  4% (1)

Explanation

During a DMO in-place migration, SUM orchestrates R3load to perform both the export from the source database and the import into the target database simultaneously, connecting them via memory pipes (named pipes/FIFOs) by default. This approach streams data directly between the R3load export and import processes without writing intermediate files to disk, making it faster and more storage-efficient than a traditional file-based migration.

Why the distractors are wrong:

• B is wrong because work processes are ABAP application server components used for business logic, not the mechanism for physical data transfer during migration.
• C is wrong because file transfer (writing export files to disk, then reading them back) is an alternative method - not the default - and is less efficient due to the I/O overhead.
• D is wrong because network socket connections are not the default transfer mechanism; memory pipes are used when source and target databases reside on the same host (which is the in-place scenario).

Memory tip: In an in-place migration, data stays in memory - R3load pipes it directly from source to target without touching disk. "In-place = in memory."
