I have a client who is running a server 2003 box (dc) w/ Exchange Ent. - they have about 100 users on the Exchange box. Probably about 30+ people use it in office all day long, plus about 30+ for webmail access. The network is crawling slow. It is on a 32bit server 03 box. The hardware is newish - maybe 1 year or so. Raid 5 on consumer grade drives.
They have really grown and its time to add something to relieve the DC of being their all in one box.
We can add a box - ideally i think Exchange should be taken off and thrown on its own box. Can I get a server 2008 in their domain and load Exchange, then migrate the mailboxes into Exchange 2010?
Is there a painless process to do this? Can a server 08 box exist if the DC is 2003 server?
I think if Exchange was off the DC then the issue of slowness on the DC will be less. Is there a better idea?
The also have a basic BESX server, and a term server, and an acct server - and these are new as well. Server 2003 for the acct, Server 08 for the BB server.
So which was to go & what is the timeline on how long this process should take ?
Thank so much all your smart guys!
