Hello all;
     I need help on some MX records and how I should address the fact that I will be moving all my users from a local hosted pop3 email server to an Exchange server environment, the trick here is that I have multiple offices (Houston, Saltlake Indianapolis) that will remain on the pop3 accounts until I can get to them so that I can change the user from using a PST to a OST. Which I have no problem.

 My confusion starts  when I start thinking about how to manage the fact that a client (outside) need to send emails to a user who now will live in the new Exchange when Im actually having a new MX record for my domain.

Can I have 2 MX records for one domain but that are two different servers with different external IPs? how?

Let me see if I can explain this a little better    
The above is my current MX record
this would be my new MX record for Exchange

how can I have a user I just migrated to exchange receive emails from his client when his client has

have in mind that I cant kill the POP 3 mail server because I will still have my other users getting emails there until I migrate them.

In other words I need both MX records up until I have migrated everyone to exchange
But they should have to be able to receive emails on whatever server they retrieve from.

Does this make sense?
