Install Exchange 2010 in an Existing Exchange 2007 Organization
Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2
You can use Microsoft Exchange Server 2010 Setup to install the first server running Exchange 2010 in an existing Exchange Server 2007 organization.
You can't perform an in-place upgrade from Exchange 2007 to Exchange 2010. However, you can install an Exchange 2010 server into the existing Exchange organization, and then move the Exchange resources, such as mailboxes, public folders, and connectors to Exchange 2010. After you perform this procedure, your organization will be running in a coexistence mode. You can maintain this mode for an indefinite period of time, or you can immediately complete the upgrade to Exchange 2010 by moving all resources from Exchange 2007 to Exchange 2010, and then decommissioning the Exchange 2007 servers.
Note
You can install Exchange 2010 in a native mode Exchange organization. However, if you create a forest in which to install Exchange 2010, you can't later add earlier versions of Exchange.
For more information about performing a custom installation, see Install Exchange 2010 Using the Custom Installation Type. For information about installing Exchange 2010 in unattended mode, see Install Exchange 2010 in Unattended Mode.
Exchange Server 2010 Deployment Assistant
Exchange Server 2010 introduces the Exchange Server Deployment Assistant, or ExDeploy, a new Web-based tool that can help you with your Exchange deployment. ExDeploy asks you a few questions about your current environment and then generates a custom checklist and procedures that help simplify your deployment.
For more information, see Exchange Server Deployment Assistant.
Prerequisites
You must ensure that each of the servers meets the appropriate prerequisites and system requirements before you begin your installation. For more information, see the following topics:
Warning
After you install Exchange 2010 on a server, you must not change the server name. Renaming a server after you have installed an Exchange 2010 server role is not supported.
Install Exchange 2010
If this is the first instance of Exchange 2010 that you're installing into your existing organization, make sure that you install the Client Access server role first, followed by the Hub Transport server role, followed by the Unified Messaging server role, and last, the Mailbox server role. For more information about the Client Access server role, see "Configure the Client Access server" later in this topic.
To perform the following procedure, the account you use must be delegated membership in the Schema Admins group if you haven't previously prepared the Active Directory schema. If you're installing the first Exchange 2010 server in the organization, the account you use must have membership in the Enterprise Admins group. If you've already prepared the schema and aren't installing the first Exchange 2010 server in the organization, the account you use must be delegated the Delegated Setup role group.

Configure the Client Access Server
If this is the first Exchange 2010 server you've installed in your Exchange 2007 organization, you need to perform several additional steps to configure your Exchange 2010 Client Access server.
If your organization requires Outlook Anywhere access, enable Outlook Anywhere as shown in the following example.
Enable-OutlookAnywhere -Server:<CAS2010> -ExternalHostName:mail.contoso.com -SSLOffloading $falseIf you didn't configure a primary external namespace during setup, configure the virtual directories for the offline address book (OAB), Exchange Web Services, Microsoft Exchange ActiveSync, Microsoft Office Outlook Web App, and Exchange Control Panel (ECP) as shown in the following examples.
This example configures the virtual directories for the OAB.
Set-OABVirtualDirectory <CAS2010>\OAB* -ExternalUrl "https://mail.contoso.com/OAB"This example configures the virtual directories for Exchange Web Services.
Set-WebServicesVirtualDirectory <CAS2010>\EWS* -ExternalUrl https://mail.contoso.com/ews/exchange.asmxThis example configures the virtual directories for Exchange ActiveSync.
Set-ActiveSyncVirtualDirectory -Identity <CAS2010>\Microsoft-Server-ActiveSync -ExternalUrl "https://mail.contoso.com"This example configures the virtual directories for Outlook Web App.
Set-OwaVirtualDirectory <CAS2010>\OWA* -ExternalUrl https://mail.contoso.com/OWAThis example configures the virtual directories for the ECP.
Set-EcpVirtualDirectory <CAS2010>\ECP* -ExternalUrl https://mail.contoso.com/ECPConfigure your Outlook Web App settings to meet your organization's needs.
To obtain the Outlook Web Access settings from your Exchange 2007 server, run the Get-OwaVirtualDirectory cmdlet.
To configure the Outlook Web App settings in Exchange 2010, run the Set-OwaVirtualDirectory cmdlet.
Configure your Exchange ActiveSync authentication settings.
To obtain the Exchange ActiveSync settings from your Exchange 2007 server, run the Get-ActiveSyncVirtualDirectory cmdlet.
To configure the Exchange ActiveSync settings in Exchange 2010, run the Set-ActiveSyncVirtualDirectory cmdlet.
Install the Exchange 2010 Hub Transport server role and the Exchange 2010 Mailbox server role into the Internet-facing Active Directory site. For configuration steps for these server roles, see Upgrade from Exchange 2007 Transport and Upgrade from Exchange 2007 Mailbox.
Change the OAB generation server and enable Web distribution on the Exchange 2010 Client Access server using the following steps.
Move the OAB as shown in this example.
Move-OfflineAddressBook "Default Offline Address List" -Server <MBX2010>Add the Exchange 2010 Client Access server as a Web distribution point as shown in these examples.
$OABVDir =
Get-OABVirtualDirectory -Server <CAS2010>$OAB =
Get-OfflineAddressBook "Default Offline Address List"$OAB.VirtualDirectories += $OABVdir.DistinguishedName
Set-OfflineAddressBook "Default Offline Address List" -VirtualDirectories $OAB.VirtualDirectories
Create a legacy host name in your external Domain Name System (DNS) infrastructure and associate this host name with your Exchange 2007 Client Access server or with your proxy infrastructure. See "Create a Legacy Host Name" later in this topic.
Reconfigure your external DNS settings or the publishing rules for your reverse proxy infrastructure to have your original namespace of mail.contoso.com point to your Exchange 2010 Client Access server or Client Access server array.
Create a Legacy Host Name
The exact steps for this procedure depend on your Internet service provider (ISP) and firewall configuration. Example steps for GoDaddy are provided to show you how this works. Your actual steps may vary. In general, you need to perform the following steps.
Create a DNS host (A) record in your internal and external DNS servers that points to the IP address of your legacy Internet-facing Exchange server (for example, Exchange 2007 Client Access server or Exchange 2003 front-end server) in internal DNS or the public IP address on your reverse proxy or firewall solution (external DNS). The host name should be in the format of legacy.domain.com (for example, legacy.contoso.com).
Create a publishing rule for the legacy host name in your reverse proxy or firewall solution to point to your legacy Internet-facing Exchange server. Refer to your proxy or firewall solution's user manual for instructions about how to do this.
Configure the existing DNS host (A) record in your internal and external DNS servers for your original host name (for example, mail.contoso.com) to point to your Exchange 2010 organization, for example, the IP address of your Client Access server or array (internal DNS), or the public IP address on your reverse proxy or firewall solution (external DNS).
For example, if your provider is GoDaddy.com, you can create a DNS host (A) record and associate it with your legacy Exchange infrastructure.
From your GoDaddy account management home page, click Domain Manager under the My Products heading in the left sidebar.
If prompted, log on to your account.
In the Total DNS section of the Domain Manager information screen, click Total DNS Control.
In the A (Host) section of the Total DNS Control screen, click Add new A record.
Enter the host name, for example, legacy.contoso.com, and enter the IP address of your legacy Exchange server in the Points to IP address box.
Choose a TTL (Time to Live) value. If you're performing this step well in advance of your Exchange 2010 installation, you can choose 1 day or 1 week from the drop-down list box. Otherwise, choose the default of 1 hour or 1/2 hour.
Click OK to complete your changes.
Verify the legacy host name is accessible from the Internet
From outside your firewall, perform the following steps, using your specific domain name.
Navigate to https://mail.contoso.com/owa, and then verify that you can access Outlook Web App for a user whose mailbox is on Exchange 2010.
Navigate to https://legacy.contoso.com/exchange, and then verify that you can access Outlook Web App for a user whose mailbox is on a legacy Exchange server.
Navigate to https://mail.contoso.com/owa, and then verify that you can access Outlook Web App for a user whose mailbox is on a legacy Exchange server.
You can also use the Microsoft Exchange Server Remote Connectivity Analyzer to verify connectivity for the legacy namespace. To use the Remote Connectivity Analyzer, see Microsoft Exchange Remote Connectivity Analyzer.
Verify Installation and View Configuration Objects
To verify that Exchange 2010 installed correctly, see Verify an Exchange 2010 Installation. After installation is complete, you can view the Exchange 2010 configuration objects in the Exchange Management Console (EMC).
Note
You can only view and manage the Exchange 2010 configuration objects using the EMC in Exchange 2010.
To verify that mail flow is working correctly, you can perform the following procedure:
Configure your Hub Transport server. For more information, see Transport Server Post-Deployment Tasks.
Create a mailbox on the Exchange 2010 Mailbox server. For more information, see Create a Mailbox.
Send an e-mail message from the Exchange 2010 mailbox to a user who has a mailbox that is located on an Exchange 2007 server. Verify that the e-mail message is received.
Send an e-mail message from a user who has a mailbox that is located on an Exchange 2007 server to the new Exchange 2010 mailbox user. Verify that the e-mail message is received.
You can also use the Exchange Remote Connectivity Analyzer to test Exchange connectivity.
Finally, be sure to perform the tasks described in Finalize Deployment Tasks that are required for the server roles that you have installed.
Important
Exchange 2010 now creates system address lists in a new container. Recipients created or modified using Exchange 2003 or Exchange 2007 management tools won’t be stamped with these system address lists. As a result, they won’t be seen by the Exchange 2010 Get-Recipient cmdlet.
To fix this issue, you must enable Active Directory virtual list view (VLV). After you have completed the upgrade of an existing Exchange 2003 organization to Exchange 2010 and have decommissioned your Exchange 2003 servers, you must enable Active Directory VLV. To enable VLV for Exchange 2010, run the Enable-AddressListPaging cmdlet. For more information, see Enable-AddressListPaging.
