What is more important is the hard disk configuration. 
For example, if the OS and the page file are on the same physical drive,
then you don't gain anything by partitioning. 

Similarly if that is just one drive being split up - again you don't
gain anything other than limiting the space the logs can use (in case
things go wrong).

Thanks Simon,

Your help puts everything in clear perspective to me.  Currently, I do
not like the way our existing Exchange Server was set up by outside
consultants prior to me being hired here.  I am thinking about changing
things around a bit.  Here is my proposed partition structure on the new
server.  Let me know what you think.

- C: - Operating System
- D: - Pagefile
- E: - Transaction Logs
- F: - Database Files

You don't need to take a specific backup for this move. 
Until you start moving the mailboxes across you can back out of it at
any point. 

The order you have is pretty good, I would suggest changing it round
slightly. Make the new machine identical to the old machine before you
move anything. So that includes third party applications. 

The other thing to be wary of is that large amounts of Exchange
transaction logs will be created. If you have a large store make sure
you have lots of space - or turn on circular logging while you move the
mailboxes. Remember to turn it off again once done!

The Blackberry server might get upset. It has a MAPI profile while may
not auto redirect. I would shut down the Blackberry services while you
move the mailbox, then run the MAPI reconfiguration tool. Once done,
bring up the Blackberry services again.

OWA will be fine - although remember that unless you are using a
frontend server you will have to be careful with the NAT redirection.
OWA redirects automatically so you may have a problem during the move. 
The other option would be to throw up a frontend server as a temporary
measure - using evaluation installations of Windows and Exchange. 

Simon.

Thanks,  you are pretty smart at Exchange.

So to be clear, this is what I have to do to move Exchange off my root
DC to new server (Member Server)

- Backup everything
- Install Windows on the new server as a member of the domain.
- Install Exchange 2000 on this server.
- Replicate all system/public folders
- Install the third party software such as GFI, NAV for Exchange
- When clients connect they will be automatically transferred to new
server because system/public folders are moved
- Remove Exchange from original server
- Remove Third Party software

Voila! Done.  The original server will still be the functioning root DC,
DNS, DHCP server

OH - Will also have a Blackberry server how will that react and also
OWA?

No you do not have to touch the clients. 
As I stated - as long as both Exchange servers are available when the
clients connect for the first time after the move, they will be
automatically redirected. No user or administration intervention
required. The key thing is to use the Move Mailbox wizard and ensure
that both servers are available. Exchange and Active Directory does the
rest.

For your DNS/MX records that depends. If you are behind a NAT firewall,
then simply redirect the NAT. you can do that at any point - although I
tend to do it when more than half the inbound traffic has to be
redirected.

I assume we will have to configure all clients to point to the new mail
server after the uninstall of the original.  How does this move affect
DNS MX records?

You want to do a swing migration. 
With careful planning it can be done with zero downtime to the users. 

A real rough outline of the process: 

Install Windows 2000 in the usual way with a unique name and add it to
your existing domain. 
Install Exchange 2000 from the CD. It will join the existing Exchange
organisation. 

Setup replication of public and system folders. For system folders,
basically follow the steps in this article up to but excluding removing
the existing Exchange server.
http://support.microsoft.com/default.aspx?kbid=307917 
Then use the "Move Mailbox" wizard to move the mailboxes across. 

As long as both servers are available when the clients connect for the
first time, they will be automatically redirected. 

Once everyone has redirected, remove the replicas of the public and
system folders - basically follow the article above to remove Exchange
correctly. 

If you know your way around Exchange then I have an article on my web
site at http://www.amset.info/exchange/migration.asp which goes in to it
in more depth. However it does not tell you how to do each stage in baby
steps, it presumes that you know how to configure replicas and other
tasks within Exchange.

Hi all,

This may be lengthy but I want to make sure I do not miss anything.

We currently have Exchange 2000 running on our root domain controller. 
There is a request to install Exchange on a new server.  Here is our
setup:

CURRENT SETUP:

- Exchange 2000 (SP2) running on root domain controller which has DNS,
DHCP installed
- GFI Mail Essentials installed
- NAV for exchange installed
- Exchange server behind ISA 2000 which publishes OWA

WHAT WE WANT TO DO:

- Move Exchange 2000 to new server + GFI + NAV with the least amount of
impact to Active Directory and Outlook client.

What is the best approach?  I am trying to do the planning for this and
want to have all possibilities and eliminate as many head aches as
possible.

Thanks,

Scott
