Migration from SBS 2003 to SBS 2008 Exchange **URGENT***
Posted on 2010-09-21
I am in the middle of a migration and there has been some questions about losing emails in the process of migrating mailboxes.
We have trend-micro spam web service that filters spam from coming into the server. The MX record is setup for the trend micro service. Non-spam email gets forwarded to our server via our firewall that is setup to forward all port 25 traffic to the old server. Should we have the firewall point to our new server or the old one?
Secondly, is there a way to test this before we start the exchange piece?
