주요 이메일과 보조 이메일 주소를 바꾸는 방법?

Continuing the discussion from Two emails for one user:

I believe there’s more UI worked planned for managing multiple email addresses, but is there any easy way to swap primary and secondary email address from the command line?

I have a few users who were merged, but now we’d like email notifications to go to the address that’s currently secondary.

I believe that you need to delete secondary, change primary to the desired address, add secondary with the other address.
