Exchange 2003 to 2010 migration

Hi,
I have a few questions on migrating from 2003 to 2010.  The existing 2003 server is not using SSL for OWA.  I will be setting up the 2010 server for SSL access.  The company has one 2003 server and will have one 2010 server.  What implications are there once I install the CAS with the 2003 server not using SSL?  Forms-based authentication is not enabled on the 2003 server yet.  I am planning to request the SSL from the 2010 server once I install the CAS role, then export/import it to the 2003 server so they can co-exist for a while.  Will there be any down time for email while I am requesting/installing the certificate?  Or can the 2003 server pretty much run by itself while I get the security set up?

SSL-Konfiguration can be. separated from Exchange 2003. Only when the mailboxes are moved to Exchange 2010 User can access via SSL.

Hi,
Thanks for the reply.  What about enabling the forms-based authentication on the 2003 server without SSL?  The two servers will still play nicely?
Why enabling the forms-based authentication on 2003. It is not necessary for Migration!

Hi,
From TechNet dd638130:
You must enable forms-based authentication on the Exchange 2003 front-end server to allow your users to access their mailboxes through a single sign-on during the coexistence period.
