Migration of Budgeting & Planning schedules
Budgeting & Planning schedules are migrated automatically. However, you must take action if conflicts with existing Financial Consolidation schedules occur.
If a conflict occurs, a placeholder schedule with the Migrate_ prefix is
      created. The placeholder schedules have no schedule details. To complete the migration, ensure
      that your accounts are not mapped to the placeholder schedule. You must either change the
      placeholder schedule to an existing schedule in the Accounts business object or create a new
      schedule.
After replacing all Migrate_ schedule assignments in the Accounts business
      object, you must manually delete all schedules with the Migrate_ prefix in
      the Schedules business object. Only then can you publish the model.
