Have introduced 2008 R2 server to a SBS 2003 domain and have installed Exchange 2010.  Is there a way to slowly migrate mailboxes while still allowing full functionality regardless of what Exchange server the mailboxes are being stored?  Do I have to add another MX record for Exchange 2010?  Guessing will lose access to OWA unless I create the DNS records.

Thanks.

Hello Webcc,

Yes, you can slowly migrate mailboxes while still allowing full functionality regardless of what Exchange server the mailboxes are being stored.

No need to create additional MX Records.

To have full functionality you need to configure your exchange servers in co-existence mode.

Please refer this article http://technet.microsoft.com/en-us/library/ee332348(v=exchg.141).aspx

Requirement for Co-existence are:
1. Two Public IP Address if you do not have ISA Server.
2. Certificate with below SAN Names:
mail.domain.com
autodiscover.domain.com
legacy.domain.com
3. Public DNS A records for legacy.domain.com and autodiscover.domain.com

After configure servers as per article I mentioned make sure that
existing traffic of mail.domain.com is forwarded to exchange 2010 for port 25, 80 and 443.

For legacy.domain.com should be pointed to another public address and traffic for this address for port 80, 443 forwarded to exchange 2003.
