Exchange 2010 - 2003 Coexistence

I have a pretty basic configuration:

Exchange 2003 standard running on a 2k3 DC
Exchange 2010 standard running on a 2k8 member server

2k3 is called:  er1.mydomain.com
2k10 is called:  er-exchange.mydomain.com
external url is:  mail.mydomain.com

Both servers are talking back and forth to each other, but I am having a problem understanding coexistence for external access.  

I was under the impression that if I swing mail.mydomain.com to point to the 2k10 server ( and modified the owa virtual server on 2010 to redirect to 2k3 ), that the 2k10 server would correctly proxy the user to his/her correct mailbox ( be it on the 2k3 or 2k10 server ).

But in reading various docs, they all indicate that I need a legacy url and a "new" url, each pointing to their respective servers for this all to work.  That is where I get hung up.

So my question:  
can I just swing mail.mydomain.com to point to the 2k10 server, set the redirects in virtual server, and then be good to go with both owa and activesync for mobile devices?

If you want to maintain both servers then you will need two URLs, with two IP addresses.
Exchange 2010 will not proxy OWA traffic to Exchange 2003.

It will proxy ActiveSync traffic, so the usual method is point the live URL at the new server, a legacy URL at Exchange 2003 and let Exchange sort out where what goes.
