  Changing the chart of accounts for one or more controlling areas to match the others.
  Creating a new controlling area that uses the same chart of accounts if necessary.
  
  
  
  
  
  Data Migration Preparation:
  
  Ensure that your data migration preparation includes a review of the controlling areas and their associated charts of accounts.
  If you are using a migration tool, ensure that the configuration settings are correct and that they reflect the intended structure of your organization.
