[otrs] customer_id change

I needed to change the customer_id from an existing user. This is what I did: (2.0.1) 1) Create a new user 2) Disabled the old one 3) Transferred the existing ticket to the new id. mysql> update ticket set customer_id='new_id' where customer_id='old_id'; 4) Now the email address is still pointing to old_id@email. For that I need to update the article table. Is there a better way to handle this? thanks. --sharif
