I cannot find this explicit upgrade path here: current exchange system is Windows 2003 R2 Sp2, with Exchange v8.3.389.2 2007 Sp2 RU15.
I need to move it to a new hardware platform (prob a Dell R520 of some sort, 16 gigs, I-5) but with Windows 2008 RTM or similar OS, and the *same* instance of Exchange, keeping the mail stores intact.
A bonus would being able to retain the same server name as well, unless Outlook 2003/7/12 can find a relocated mail store by itself.
The HW upgrade paths I have seen so far specify the same ver. OS at both ends; obviously I need to dump 2003. I don't believe Exchange 2007 would survive moving intact to server 2012 (am I wrong?), but would appreciate an update procedure to either OS.
