Just did a migration from Server 2003 running exchange 2003 to SBS 2011.
I did things pretty manual. For most of the mailboxes, I just did an exmerge and then uploaded the PST files via PST capture.
I understand that users may/will receive and error when replying to an email from the 'old' server unless they enter the x500 address. I've added the x500 address to a particular account but I figure it might be wrong.
A user tried to send a new email to someone else in the same office and it bounched back straight away with the following:
Delivery has failed to these recipients or groups:
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.
