I have jira users that are importing data and it is resulting in creating New Users with their user name as FirstNameLAstName with email as Noreply@email.com even though those users exist in the system as FirstIntialLastName@domain.com
Jennifer Doerre jdoerre JDoerre@Healthgrades.com
Jennifer Doerre jenniferdoerre firstname.lastname@example.org
So what is your question? have to create a profile name lastname first name initial and middle ititial. e.g. jennifer Doorre would be DoerreJe
Jane M smith would be SmithJM
before importing it into JIRA. If the users in the csv have profile names already in your JIRA instance then they have to be matched up.
