I have a 2003 smb server that is in process of being replaced by a server 2008 r2 in a new domain. We had issues with the old domain and exchange was having issues as well with space. &nbsp;The 2003 smb has exchange on it, acitve and currently being utlized in production. We created a new domain and &nbsp;the new 2008 r2 server is a domain controller, &nbsp;we have loaded exchange 2010 on the same server. &nbsp;I created a test environement and the server is working properly sending and reciving email, thru a separate test internet domain configuration with pointers and mx records. &nbsp;We now need to move or migrate the mailboxes and the public store from the 2003 exchange on a different domain to the new 2008 exchange server on the new domain. &nbsp;does anyone have sugestions on how to proceed?

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).
