In the case of duplicate learner profiles in the Destiny One Registration System, you may request to have them merged.  You will need to specify the profile to retain the academic and account information.  

Learner Profile Merge Request Form

In the event that you have updated the learner's preferred email address, please use this form to request that their username also be updated.  Changing the username will change the email address the learner will need to use to log into Destiny One, so be sure the learner is aware of, and has approved of this change.
