Yes.  Assuming you're building a new server, you install W2K8 (has to be SP1 for you to install Exchange 2007).  Install Exchange 2007 into the organization so you will have an org with a 2k3 and 2k7 Exchange server.  It will create an administrative group for the 2k7 server (do NOT rename this).  Be aware that it will take over SMTP for the organization when you do this, so be prepared to make changes to firewalls, SMTP gateways, whatever is between the internet and the server for mail delivery to point to the new server.

Once you've set up the Exchange server (which will require setting up send / receive connectors and a few other things) you can move mailboxes, public folders, and other things (perhaps schedule free/busy, Offline address books, etc.).  

THen retire the old server.  This isn't a comprehensive explanation, but MS has articles about installing the server, and the steps to remove the old server.


what are the steps
i am confused if first i had to install win2008 in new 64 bit server with the same name or other and then install exchange and then only migrate datas.
are the process occurs conflicts or what pls
guide me the initial steps and the steps i had to do one be one


This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

You will need to build out the 2008 box and join it to the domain and then run adprep from the 2008 DVD and allow the AD to replicate across the domain.  Perform the following steps:

Installed Windows 2008 on your new machine and name it DIFFERENTLY (e.g. DC2008)
Join DC2008 to the current domain (e.g. MYDOMAIN)
Run adprep /forestprep & adprep /domainprep on the 2003 based domain controller(s)

You can see the ENTIRE process here on the 2003 AD upgrade to 2008 AD:


Once you have finished the AD upgrade in your domain you need to let the schema replicate.
Adprep /ForestPrep for Windows Server 2008 extends the schema and sets the ObjectVersion attribute to 44 in schema if Adprep ran successfully.

To check objectVersion:

Install LDP.exe from Support Tools on a DC running Windows 2000 or Windows 2003.
Run LDP.exe, go to Connection and then click on Bind.
Click Ok. Next click on View, Tree and then select the following LDAP path from the dropdown list: CN=Schema,CN=Configuration,DC=domain,DC=com
Click Ok to run the LDP query against the above LDAP Path.
In Right Pane, check objectVersion: 44 attribute. If it is 44 Admin /ForestPrep was run successfully!

You can now install exchange 2007 by following the link that I gave you before. (Personally I would install it on a different 2008 machine that is in the domain (not a domain controller)).

If successful then you are ready to introduce a 2008 DC (IF YOU WISH) into the domain by following this:

can i upgrade my existing win2003 32 bit server with exchange 2003 to win2008 and exchange2007.
by installing win2003 64 bit os and exchange 2003 and merging all old servers data to new one and then upgrade to 2008 and exchange 2007.
is it possible
previous is also the good one but i want to make sure not to loose all datas.

1/2 of that.  You can upgrade your existing Win2k3 box to Windows 2008, but you CANNOT run Exchange 2007 on a 32bit machine.  

Your solution is not a good one partially because I may be missing something when you say:
"by installing win2003 64 bit os and exchange 2003 and merging all old servers data to new one and then upgrade to 2008 and exchange 2007."

Why?  You can just follow the solutions above and you will be fine.  No loss of data will occur.  

You cannot 'Upgrade' exchange 2003 to 2007.  You can only migrate over to 2007.  You will have them both running at the same time.  Then you will start moving messages between them and then eventually you will cut over to the 2007 exchange server completely.  

The above instructions explain ALL of this, and what my personal recommendations are.  I think that you are over thinking this a bit :)  Just take as step back, read through the instructions above (all of the links) and suggestions and follow them step by step as they are proven to work.  They are excellent resources for your project and you should be able to complete it with all of this and not have to worry about losing data.

Good job on being so diligent!

And Good luck
