New install of exchange 2010 on new windows 2008 server that is NOT the DC

Hi all. This is way out of my experience zone...  We currently have one server in the office running windows 2008 R2 and it is the DC and runs exchange 2007 & SQL server 2008.  We want to run exchange 2010 and see this as an ideal opportunity to separate out some functions from the main server.

So I have installed 2008 (Standard) on a new machine and I just cannot find an understandable resource that tells me the steps to go through to set up the roles on the new server, tell it where the main DC is and then install exchange 2010...  any help greatly appreciated!

First thing you need to do is install the pre-requisites on the server Exchange 2010 will be installed on: http://technet.microsoft.com/en-us/library/bb691354.aspx
Note the different scripts for Windows 2008 and Windows 2008 R2

Then you need to run:

setup /adprep
setup /domainprep

from the Exchange 2010 DVD.  If you haven't done this the Exchange 2010 installation will do it for you so don't worry too much.

Then install Exchange, if you plan to remove the 2007 server then you will need to install the Hub Transport, Mailbox and Client Access roles.

Are you sure about this? Exchange 2007 does not run on Windows 2008 R2?

You can only deploy Exchange 2010 in an Exchange 2003 or Exchange 2007 organization that operates in native mode. The following steps show you how to use Exchange System Manager to change the Exchange organization to native mode on an Exchange 2003 server

   1. Start Exchange System Manager. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
   2. Right-click the organization and then click Properties.
   3. Click the General tab, and then, under Change Operations Mode, click Change Mode. Click Yes if you are sure that you want to permanently switch the organization's mode to native mode.

Windows Server 2008 R2 Enterprise

From Exchange Server/about:
Exchange Server 2007

It definitely works, trust me! (well, there are a few issues, maybe that's the problem!)

Anyhow. A few issues. Before I asked this question I installed the Active Directory Domain Services on the new 2008 standard server.  I then ran dcpromo and tried to add the server as a secondary domain controller in an existing forest but it said it couldn't find a domain controller for the domain.  I can ping the domain controller via ip and via its netbios name though?

I tried running the scripts mentioned, the "sc config NetTcpPortSharing start= auto" one worked fine, but the "ServerManagerCmd -ip Exchange-Typical.xml -Restart" errors with "Readerror: Answer file does not exist: Exhange-Typical.xml"

Ah, I'm being a muppet, forgot to change to Scripts directory... I'm running through the scripts now.

That's interesting because I have tried many times to get Exchange 2007 to install on R2 and it fails every time even with a bit of "hacking"

Have you got the new server pointing to the existing server for DNS?
There should be no other DNS servers in the networking properties.

You don't need to install the ADDS component, just run DCPROMO however I would recommend not installing it as a domain controller if you can avoid it.

It was a bit of a struggle to get it installed!  I think it only worked when I got hold of 2007 sp1 or something? Can't remember now.  

I thought I had to run dcpromo?  I'm happy to do what is right, I don't want to make the new server a domain controller as it doesn't need to be.  This is what I was struggling to find resource-wise!

In the local area network connection, I've manually configured the IPv4 settings to an ip within the office network range and have set the preferred DNS server to be the ip address of the existing 2008 R2 machine. Default gateway is the internal IP of our router.

It can now see the existing domain in dcpromo, but I've not continued through the setup yet in case you tell me not to do it!

No, you don't need to run DCPROMO this is only to make it a domain controller.

I'm still struggling here chaps!  Gone back to try theis again and I cannot get it installed.  The problem is that I can't get Exchange 2010 installed on the new server in the existing Active Directory site as there is also Exchange Server 2007 SP1 installed. I can't upgrade that one to SP2 as it's on Windows 2008 R2 and that forbids me upgrading to Exchange 2007 SP2!

So... all I need to do is get 2010 installed somehow, transfer existing mailboxes and then deinstall exchange 2007.  Can I maybe put the new server temporarily into a new active directory site or will that be impossible to then change to belong to the existing domain once I deinstall exchange 2007 from the current domain controller?

Glen KnightCommented:
Exchange 2007 is not supported on 2008 R2 which is why you cannot apply service pack 2.

The 2010 server are you tryingto install it on a completely different domain?
0
Glen KnightCommented:
Also Exchange 2007 must be running Service Pack 2 for it to co-exist with Exchange 2010

carledAuthor Commented:
Yeah, we had the conversation before a few posts up!  Remember I somehow managed to get exchange 2007 installed on 2008 R2 anyway!

This is a new server. It will only be a mail server. Currently the domain controller is a mail server and we don't want it to be a mail server any more and want to put the mail handling onto a new machine.  The existing mailserver handles 3 or 4 incoming domains.   I just want to get 2010 installed somehow, transfer over the existing stuff from 2007 then deinstall 2007 entirely.

However as the new server is part of the existing domain, it won't let me install 2010 as it says it can't coexist with 2007 SP1.

Glen KnightCommented:
The only way I see you getting around this is first installing a 2007 server in a new 2008 server that is not R2 decommision the existing exchange install onto the new 2007 one.  Then upgrade to SP2 then install Exchange 2010

alternatively wait a few months for Exchange 2007 SP3 which will provide support for 2008 R2 then migrate to 2010

It's the only option you have I am afraid.

It's getting further than 2010...  Installing files ok so far.

Is there an easy "how to" on transferring settings/mailboxes from one ex 2007 server to another anywhere please?
