I think as long as you still control the private keys, sending funds to the corresponding public key should be fine. Public keys are derived from the private key. (they should be, that's how it work in bitcoin). But to be be safe you could always make a new account and send funds there then you can send them back to yourself once you are up and running on 2.0
EDIT: I am talking about send funds to the key (BTS...) not to the account
