You are able to transfer to any other available legacy server or your friends can transfer to your world. The only other free transfers I see them doing at a later time is maybe targeted transfers from high to low pop servers.

As for the economy thing. They wanted to wait somewhere around 6 months (forget exact range of time they gave) to allow the new players to form their own economy on their own without disruption of legacy gil or all classes 50 from the start. Agree or not they are sticking to this.
