OK  - you are pretty much through the 2003 to 2008 environment migration.

Leave exchange 2003 alone - perform the migration to Exchange 2007 BEFORE you kill the Exchange 2003 box

*****Exchange 2003 > 2007 Single Server*****
(Updated 020409)

This assumes the new server will hold the Mailbox, Hub transport, and Client Access Roles.


*****Pre Exchange 2007 Install Server and domain Tasks******


1. Before you start, all existing Exchange 2000 servers should be at SP3 and all Exchange 2003 Servers should be at SP2.
Start > All Programs > Microsoft Exchange > System Manager > Administrative groups > First Administrative Group {NB yours may be name differently} >  
Servers >See the right hand pane for Build Numbers.

Build Numbers are.....


Microsoft Exchange 2000 Server                      6.0.4417                  October 2000

2. All Exchange 5.5 Servers need upgrading to Exchange 2000/2003 before you start.
 Note: If you have any Legacy AD connectors from an Exchange 5.5 Upgrade these need removing before you start. (If you remove it from add remove programs you might get an MSDE error ? ignore the MSDE Error and it should uninstall. If not get the Media that AD Connector was installed from and run D:\ADC\Setup\i386\Setup.exe to get rid of it.) If all else fails you can remove the connector with ADSIEdit (Last resort)

3. Ensure all Domain Controllers are (At Least) SP1 Preferably SP2
 Note: You need 381Mb Free on the system plus 170Mb free space to install SP2.

4. Set the domain functional Level to "Windows Server 2003" (Windows Server 2000 will work). Start > Run > dsa.msc {enter} > Right Click the domain name  
> Raise Domain Functional Level > Select Windows Server 2003 > Raise > OK > OK.

5. Server needs mmc version 3 installing (Installed by Default on R2) http://support.microsoft.com/kb/907265 (About 8Mb)
 Note: If your service packed up you may already have MMC 3.0 installed.

6. Server needs Powershell 1.0 or above installing. Http://support.microsoft.com/kb/926139 (About 2.5Mb)

7. Server needs the following windows components installing, Start > Run > appwiz.cpl {enter}

Application server > IIS > World Wide Web Services.
Application server > Enable network COM+ access.

Note: Unlike previous versions of Exchange SMTP and NNTP should NOT be installed.

8. Server needs the following windows components installing .net framework 2.0 (windows update)

9. Download and run the Exchange Best Practice analyser (Note this can save you many headaches due to Exchange 2003 problems.) Download it straight from M$ to get the latest version.

I have on one occasion needed to copy all the DVD/CD's contents to the server for Installation to be successful.


1. Assuming the CD/DVD from which you are deploying exchange 2007 from is D: Start > Run > CMD {enter}
2. Execute the following command "d:\Setup.exe"
3. Click Step 4 > Introduction Screen > Next Tick "I accept the terms...." > Next > Next > Select Typical.

5. Exchange 2007 will now do some checks.

Note: If you receive a warning about replicating the free/busy folder see free/busy note below.

6. Click Install > When done > Finish.

7. Launch the Exchange Management Console > Ignore any Licence warnings.
8. Select Server configuration > Select the new Server > Action > Enter Product Key > Type in your Key > Read the Warning > Finish
9. The new 2007 Org will have 1 mailbox database and one Public folder database Expand Microsoft Exchange > Server configuration > Mailbox > Select the  
server > The Databases will be displayed in the center panel at the bottom.
10. You can select the databases > Right Click > "Move Database Path" to move them onto another partition.

*****free/busy Note******

1. You need to set up replication to the new Server. (If you got the warning message above)
2. On the OLD 2000.2003 Server > Start > All Programs > Microsoft Exchange > System Manager.
3. Administrative groups > First Administrative group > Folders > Right Click > View system Folders.
4. Expand Shedule+Free Busy > Select the Folder(s) below it > Right Click > Properties > Replication > Add > Select New Server > OK

8. Other Public Folders are replicated like older versions of exchange (set up the replica on this server > Replicate the folders > Remove the original  
replica)


*****Point SMTP Feed to the New Server*****

The MX Record should now be pointing to the public IP of the new server OR the Firewall SMTP Port re-directs needs changing to the new server.


*****Migrate the Mailbox's*****

I usually migrate the domain administrator?s mailbox, test mail flow then move the rest of the mailboxes


1. Move the mailbox's, in EMC Expand Recipient configuration > Mailbox > Select the mailbox's to move > Move Mailbox.
2. Select the New Server > Next > Skip the mailbox > Next > Immediately > Next > Move.
3. If you do not have a server deployed as an Edge Transport Server then you need to add some settings, in the EMC > Server Configuration > Hub  
Transport > receive connector (Default {server name} > Properties > Permissions Groups > Tick Anonymous users.
4. Expand Organization Configuration > Hub Transport > Send connector > Right Click > New Send Connector > Give it a Name > Set Intended use to  
"Internet"
5. Next > Add > Simply enter an asterisk > Tick and sub domains >? OK > Next > Add a smart host if required > Next > Next > New > Finish.

NOW REBOOT the Exchange 2007 Server and Ensure the Microsoft Exchange Information Store Service Starts correctly when the server boots.

6. Move all the remaining Mailbox's.

Note: If a user has been disabled, and you try to move that users mailbox you will get an error.


*****Install Antispam Agents*****

1. Start > All Programs > Microsoft Exchange Server 2007 > Exchange Management Shell.
2. Execute the following commands
 cd "c:\Program Files\Microsoft Exchange Server\Scripts" {enter}.
./install-AntispamAgents.ps1  {enter}.
Net stop "Microsoft Exchange Transport" {enter}.
Net start "Microsoft Exchange Transport" {enter}.
3. Stop and restart the Exchange Management Console (NOT the exchange Management Shell).

Note: If the antispam Agents are installed remove the following folder from the backup (Or it will error).
C:\Program Files\Microsoft\Exchange Server\TransportRoles\



*****Decommission the OLD Exchange Server*****


Note: Clients with Older Versions of Outlook (Pre Outlook 2007) will need to log into their mailbox at least once before you remove the old server (To  
pick up the new mapping to their Mailbox).

1. On the Legacy Server Launch ESM > Recipients > Recipient update services > Change the server for all settings to the new exchange server.
2. If it?s a single server site you can now remove the Global Catalogue role from the Old Server and demote it to a member server.
3.  After everything is moved and tested you need to remove the connector from the 2000/2003/or to the 2007 org. On the Legacy exchange server launch  
the Exchange System Manager > Administrative groups > Routing Groups > Routing Group > Connector > Delete.
4. Remove the original Exchange server, note if you use public folders leave the Management tools installed as 2007 cannot manage them (from EMC ? this  
is going to be fixed).

5. Re-run the Best Practice analyser against the 2007 server to make sure there are no problems.


*****Post Install Tasks*****

1. You may need to Exclude the following folder from the backup.
C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\CONFIG\
2. If OWA displays "Service Unavalable" See http://support.microsoft.com/kb/894435 and run through the ASP.NET 2.0, 64-bit version section.
