Cause

Leaver with same name exist in customer AAD or has been created in previous migration run.

Solution

1. If the Leaver was created a s apart of the migration and it's confirmed it's correct user step can be skipped

2. If the leaver was not created by migration but already exist then the Leaver Constructed UPN need to be change for the leaver in the database table "dbo.LeaverMappingselection" and leaver migration need to be restarted.
