You are performing an SAP S/4HANA conversion. When does the silent data migration (SDM) take place?

Question

Options

• ADuring the Execution roadmap step
• BDuring the SUM technical downtime
• CBefore the start of the SUM technical downtime
• DAfter SUM has ended

• A
  2% (1)
• B
  4% (2)
• C
  2% (1)
• D
  92% (47)

Explanation

Silent Data Migration (SDM) is designed to reduce technical downtime by deferring certain data transformation tasks to run in the background after SUM has completed and the S/4HANA system is already live in production - making D correct. This means users can resume work on the converted system while SDM quietly processes large data volumes behind the scenes.

Why the distractors are wrong:

• A (Execution roadmap step): The Execution phase describes SAP Activate project methodology, not the technical trigger for SDM - these are different frameworks.
• B (During SUM technical downtime): Downtime is used for the core technical conversion (table restructuring, code activation, etc.); SDM explicitly exists to avoid burdening the downtime window with all data changes.
• C (Before SUM technical downtime): Pre-downtime activities cover preparation and checks (e.g., Maintenance Planner, pre-checks) - SDM has not yet been triggered at this stage.

Memory tip: Think of the word silent - SDM runs quietly after the noise of the downtime is over, while the business is already back up and running. If it happened during downtime, it wouldn't need to be "silent."
