Install Exchange 2010 without affecting users.

We have a single 2003 exchange server.  Is it possible to install Exchange 2010 on the domain and not affect current 2003 users?  I would like to install and setup the cas/hub/mbx to the point where I can do the certificate wizard without pointing the dns to new server.  Is this possible?

madhatter5501and Jodiddy, Saw those articles.
KS_admin, Had not seen that article, however it does not answer my question.

So installing 2010 will break the active sync, BES server and OWA, even if I do not change the DNS entries from the 2003 server to point to 2010.

Is that correct?

When you say install Exchange 2010, what roles would you be installing initially?  Would you be installing 2010 as a member of the existing Exchange 2003 Org?
