We currently have exch2003 with a fe/be config running on 2003 enterprise. We have an available 64bit ProLiant DL380 G5 server that we would like to use to install 2008 enterprise server 64bit along with exch2010. It currently has 3gigs but we will add another 8gigs to it (11 gigs total).
Right now we're setup with a fe/be but we only have 1 64bit server so we cant do a fe/be exch2010 setup. Is it possible to keep the 2003 as a fe and the 2010 as the be? Or will we end up with a single exch2010 box?
And are there any good guides out there to upgrade from 03 to 10? and the reason for the upgrade? well to attempt to get unified msesaging implemented :)
