Exchange migration (HW and OS changes)

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.

Thank you.

Better you setup Exchange 2010 or 2013 on new server. I will suggest to go for 2013. FYI, MS already release Exchange 2016 and in future you cannot migrate from 2007 to 2016. Best practice to use n-1 and you are already n-2. Being said that, if you still want to stick to 2007.

Just install new Server with Windows 2008, install new Exchange 2007 Server. Setup, new db's. Cut over all OWA, Active sync, ecp etc to new server. Move the mailboxes and decommission the old server. Remember you also need new certificate.

I'd like to bump to E201x but we are swamped.  And budget challenged.  Thank you.

Ya, I understand that, so better you setup new Exchange 2007 on new server and perform the cut over.

There is no need to retain the existing server name.
Exchange will find the new location after a move mailbox as long as both the old and the new server are available.

Therefore as already outlined, simply install Exchange 2007 SP3 (use the SP3 download from Microsoft to do that). If you also download the latest rollup and put it in to the Updates directory of the extracted service pack before you do the installation, then it will be applied a the same time.

Windows 2008 will be fine - NOT 2008 R2 as it isn't supported for Exchange 2007.
Service pack it, then patch and patch and patch again, rebooting when prompted until no more patches are required.

Indeed.  Thank you.

Eeesh.  I can hardly understand what he's saying with that accent!  Can you point me to migration documentation online?  I will search the MS site, which is always a thrill.

Ah, much better, thank you.  I liked the "one day" promise I heard in the video, altho I'm not hopeful about that.  And I am assuming that I will have to change the MX records for our email URL (for clients and OWA) to point to MS.

I'm sure this is good information for IT staffs which actually have time for MS Exchange upgrades.  We simply do not.
