Upgrading exch03 with FE/BE config to exch10 (possibly no FE/BE)

hello everyone.

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 :)

thanks!

1) No It is not possible to keep the 2003 as a fe and the 2010 as the be ,Please end with single exch2010 box

Upgrade existing Exchange 2003 servers to Exchange 2003 Service Pack 2 (SP2).
Deploy Exchange 2010 servers in this order:
Client Access
Hub Transport
Unified Messaging
Mailbox
Configure the Exchange 2003 front-end server and the Exchange 2010 Client Access server.
Configure the Exchange 2010 Hub Transport server and the Unified Messaging servers.
Move mailboxes from Exchange 2003 to Exchange 2010

2) And are there any good guides out there to upgrade from 03 to 10?

thank you for the great resources, I read the first link and second one is just going to open up more questions.  It's definitely a completely different monster to configure unlike 2003.

I do have another question:

Can I setup exchange 2010 and just have it sit in our forest quietly without interfering with our 2003 fe/be configuration?  Then when we're ready we can start performing the mailbox moves?  Or does the implementation of 2010 need to happen when we're ready to decomission our 2003 exchange?

Thank yoou

Viralrathod, that link gave me some extra info but it doesnt state if I can leave 2010 sittig on the network.  the steps provided seem to assume an immediate transfer of mailboxes and leave the fe/be running for a few weeks to make sure all is good.
