A systems administrator asks whether non-disruptive migration (NDM) is supported between their VMAX All Flash arrays. The arrays are located 800 km apart.
What information should be provided to the administrator?

NDM (Non-Disruptive Migration) is generally not feasible over long distances because it typically requires a synchronous link to ensure data consistency between the source and target arrays during migration. Since the arrays are located 800 km apart, maintaining a synchronous link over such a distance is impractical. Therefore, NDM is not supported between the arrays in this case.
