How to save user data (in the order's data) when delete the user

Hi all, when an user make an order his/her uid and email are stored in the order's tables (I don't know which one, but this is not important).

When the user (or the administrator) delete his/her account all orders related to this user lost account information so in commerce there are orders without uid and email, and I think that is not correct.

How can I resolve this problem ?
