Migrating from Exchange 2003 server to Exchange 2010

I'm migrating our companies  mail (about 50 mailboxes) from Exchange 2003 t 2010. Is this an automated process or do I need to manually copy pst file across to the new server.

Also, can both servers run side by side?  My plan was to move my mailbox and a few others to the new server, make sure it's running correctly and them migrate the rest of the mailboxes... Is the the correct way of doing this move?  Is it even possible?

Any help appreciated as I've never build an Exchange server before or migrated one.

You can go through below articles at my blog:

yes, You can run both servers side by side. but once you moved all the mailboxes you'll need to start all your mail flow from exchange 2010 and need to remove the exchange 2003.

You have to move the mailboxes over manually, but you can choose which ones (all/some/one) and schedule the move. You can run Exchange 2010 in an 2003 Organization without problem.

Does the machine that exchange 2010 is install on have to be a DC?

No. In fact, it should NOT be a DC if you can avoid it. Exchange servers are resource hogs (even if Exchange 2010 is more relenting than the older ones) and with the CAS role you get IIS which should not be on a DC for security reasons.
