Just looking for some thoughts on migrating an existing 2003 domain to either SBS 2011 or 2008 domain. I definitely want to move to a new platform whether it is a 2008 domain controller or SBS 2011. I currently have a stand alone Exchange 2003 server that is aging. Soon the Exchange server will either need upgrading to 2010 on a new box, use SBS for Exchange, or move Exchange to the cloud. I have just ordered one new server (for a file server) and I am contemplating which OS to install on this new server. Not sure I want to get locked into the SBS thing but it would be easier to migrate Exchange over I suspect so I wouldn't have to purchase another server for Exchange 2010. Any thoughts or advice on which direction I should take is appreciated.
