Cause: All Views Active: The error suggests that the system is trying to perform an operation that requires some views to be inactive or in a specific state, but all views are currently active.
Configuration Issues: There may be a configuration issue in the migration cockpit or the data migration project that is causing this state. Process Flow: The process flow may not be correctly followed, leading to all views being active when they should not be.
Solution: Check View Status: Review the status of the views in the migration
