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?

We did this, we did a "swing migration" which worked great.  Basically it joined the 2010 to the existing Exchange organization, and we had them both running side by side.  We were able to move mailboxes from one to the other with no interruptions to the users, and I was really pleased.

Here's a link to one of the guides I used:

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?

So I see you want to install CAS, HUB and MBX on the 2010 Server.  Well, if you follow the steps for coexistence I don't see that just installing it will cause OWA, BES and ActiveSync to break.

To get to the point of being able to use the certificate wizard you only need CAS installed.
