Before updating or upgrading an S/4HANA system, how do you find out which simplification changes will hit you, given that the old release cannot know the new release's catalog?

A customer wants an S/4HANA update with no technical downtime at all. Why is SUM's Zero Downtime Option not something you can just switch on, and why do many customers ultimately abandon it?

SUM's near-zero-downtime scenario migrates data while users are still working. What technical mechanism makes that possible, and why is it usually applied to only a few tables?

You are configuring SAP Note downloads on an S/4HANA system and the guided procedure offers three transfer methods — HTTPS, the central Download Service, and Remote Function Call. Which one is off-limits, and what does the Download Service give you that a plain HTTPS download does not?
