Topic Last Modified: 2008-03-11

This topic explains how to use the Microsoft Exchange Server 2007 SP1 Setup wizard or a Command Prompt window to upgrade from the release to manufacturing (RTM) version of Exchange 2007 to Exchange 2007 Service Pack 1 (SP1). If you have one or more Exchange 2007 server roles or the Exchange management tools installed, you can upgrade to Exchange 2007 SP1.

In some cases, you may want to upgrade an Exchange 2007 SP1 server again. For example, if the first upgrade failed for one or more server roles, you must use either of the procedures in this topic to upgrade again.

Note:
   When installing Exchange 2007 SP1 on multiple Exchange 2007 servers within an organization, we recommend that you first upgrade the Client Access servers. In an organization that has multiple Active Directory sites that use multiple Client Access servers in a proxy situation, you must upgrade the Internet-facing Client Access servers before the Client Access servers that are not Internet-facing.

Before You Begin

Before you begin the procedures in this topic, be aware of the following:

  • You must have Exchange 2007 installed.

  • Your organization must meet the requirements that are listed in Exchange 2007 System Requirements.

    Important:
    It is not supported to upgrade your operating system to Windows Server 2008, and then upgrade to Exchange 2007 SP1. It is also not supported to upgrade to Exchange 2007 SP1, and then upgrade your operating system to Windows Server 2008. To deploy Exchange 2007 SP1 on Windows Server 2008, you must install Windows Server 2008 on a computer that does not have Exchange installed, and then install Exchange 2007 SP1.
  • We recommend that you stop and then restart the Remote Registry service.

  • You cannot use the Setup wizard to upgrade a clustered Mailbox server. For more information about upgrading clustered Mailbox servers, see Upgrading Clustered Mailbox Servers to Exchange 2007 SP1 or SP2.

  • When you upgrade an Exchange 2007 RTM server to Exchange 2007 SP1, you upgrade all the server roles that are installed on that server.

  • After you upgrade to Exchange 2007 SP1, you cannot uninstall the service pack to revert to Exchange 2007 RTM. If you uninstall, you will remove Exchange 2007 from the server.

  • Ensure that the fully qualified domain name (FQDN) setting that you specify is the FQDN for your server. If you have a FQDN specified that is not the FQDN for your server, Exchange 2007 SP1 installation will fail.

Required Permissions

The following permissions are required to upgrade to Exchange 2007 SP1:

  • To upgrade the first Exchange 2007 RTM server in your organization that has the Client Access, Hub Transport, Mailbox, or Unified Messaging server role installed to Exchange 2007 SP1, the account you use must be delegated the Exchange Organization Administrators role. The account must also be a member of the local Administrators group on that computer.

  • To upgrade an Exchange 2007 RTM server that has the Edge Transport server role installed to Exchange 2007 SP1, the account you use must be a member of the local Administrators group on that computer.

  • After you have upgraded the first of each Exchange 2007 RTM server roles in your organization, to upgrade additional servers to Exchange 2007 SP1, the account you use must be delegated the Exchange Server Administrators role. The account must also be a member of the local Administrators group on that computer.

  • To upgrade a computer that has only the Exchange management tools installed, you must log on by using an account that is a member of the local Administrators group on that computer.

  • If you have not yet prepared the schema for Exchange 2007 SP1, the account you use to upgrade the server must be a member of the Schema Admins group and the Enterprise Admins group.

    Note:
    You must prepare the schema in the same domain and Active Directory site as the schema master. If the first server that you upgrade is not in the same domain and Active Directory site as the schema master, or if you want to prepare the schema separately from upgrading the first server, you must run Setup /PrepareSchema from a Command Prompt window on a computer that is in the same domain and Active Directory site as the schema master.
  • If you have not yet prepared Active Directory for Exchange 2007 SP1, the account you use to upgrade the server must be a member of the Enterprise Admins group.

    Note:
    You must prepare Active Directory in the same domain and Active Directory site as the schema master. If the first server that you upgrade is not in the same domain and Active Directory site as the schema master, or if you want to prepare Active Directory separately from upgrading the first server, you must run Setup /PrepareAD from a Command Prompt window on a computer that is in the same domain and Active Directory site as the schema master.
  • If you have not yet prepared the domain for Exchange 2007 SP1, the account you use to upgrade the server must be a member of the Domain Admins group.

    Note:
    If you want to prepare the domain separately from upgrading the first server, you must run Setup /PrepareDomain or Setup /PrepareAllDomains from a Command Prompt window.
