Step by Step Comprehensive Detailed Explanation:

In an MDM (Migration for Dell EMC) migration, data is moved from a source array to a target array. When the symdm sync -stop command is issued, it puts the migration into the CutoverNoSync state. This state signifies that:

Synchronization Stopped:Active data synchronization between the source and target arrays has been stopped.

Data on Both Arrays:However, the customer data still resides onboththe source and target arrays. This is because the CutoverNoSync state is a transitional state that allows for a controlled cutover to the target array.

The next step would typically involve a cutover operation, where host access is switched to the target array, and the source array is removed from the migration configuration.

Why other options are incorrect:

A. Only the target array:While the goal is to eventually have the data only on the target, in the CutoverNoSync state, data still exists on both arrays.

B. Only on the source array:Data has already been partially or fully copied to the target array during the migration process.
