The Migration Utility keeps track of what has already been migrated by updating the Exchange data file that it creates in its installation directory. This CSV (comma-separated value) file is named exmigdata.csv by default. You can view and edit this file as a spreadsheet.
The Migration Utility also creates GroupWise objects in eDirectory as it migrates data.
To re-migrate a user, delete the User object from GroupWise. Rerun the Migration Utility and select the user for migration. You do not need to update the CSV file.
To re-migrate a distribution list, update the CSV file to remove the migration date of the distribution list. After you remove the migration date, the Migration Utility does not know that the distribution list has already been migrated and it migrates it again as if for the first time. You do not need to delete the Distribution List object from GroupWise.
To re-migrate a public folder, delete the folder Resource object from GroupWise. Rerun the Migration Utility and select the public folder for migration. You do not need to update the CSV file.
