One possible workaround is that you fix the situation directly in the Database following this procedure:

• 1. Stop Fisheye/Crucible instance

  2. Locate the ID of both the old user and new user in the database:

     select
     new_user.cru_user_id,
     old_user.cru_user_id
     from cru_user old_user
     cross join cru_user new_user
     where old_user.cru_user_name = 'OLD_USER_NAME - to be modified'
     and new_user.cru_user_name = 'NEW_USER_NAME - to be removed'

  3. Follow the procedure corresponding to the database you are using
