If your organization has defined solution workflow statuses to mark the current validation status for actual performance data like phase start/end dates, effort, project size, and defects, tagging imported Closeout records at the time of import (as opposed to editing them one at a time after import) can save you a lot of time! Of course, you should only assign a status if you have previously verified that all projects from the source SLIM-DataManager database should have the same status. If your database contains data with mixed validation statuses, consider dividing the database into smaller files where every project in each database file can safely be assigned the same workflow status.
