After the upgrade, you'll have a new email address (ending in @myemail.indwes.edu). Your new email address will be your current username followed by "@myemail.indwes.edu" (instead of @student.indwes.edu).
Current username: joe.doe
New email address: firstname.lastname@example.org
Don't worry! You will continue to receive any email messages sent to your previous (@student.indwes.edu) address.
