Can I use sbs 2003 exchange as a frontend on the dmz and sbs2008 exchange as the backend on the Lan?
Posted on 2009-04-09
I am migrating to sbs 2008 from sbs 2003 and since there is no upgrade path, I will be buying a full version. I currently have an old mail server sitting on our dmz and have sbs2003 exchange pop the dmz mail server for our mail... this works but there can be up to a 15minute lag between pops. When I finish migrating to sbs2008 can I use my old sbs2003 on the dmz, allowing it to relay mail instantanously and host outlook web acess. Has anyone done this?
