Abstract: A computer system for migrating human resources data from a first human resources data system to a second human resources data system. The computer system may comprise an import utility, a translation utility an export utility and a reports utility. The import utility may be for receiving first employee data from the first human resources system comprising employee attributes and applying an equivalency formula to a first employee attribute of the first data to convert the first employee attribute from a first human resources data system format to a target format. The translation utility may be for applying a translation table to the first data to generate translated data according to the target format; and storing the translated data at the target database. The export utility may be for generating an export file comprising the translated data arranged according to the second human resources data system format.
