Understanding Exchange 2003 upgrade prerequisites

 

Before you can really start to use the Deployment Assistant, your system and servers must meet requirements. If they don't meet these requirements, you won't be able to complete the steps within the tool and you won't be able to deploy Exchange 2010. This topic provides information about the following:

  • Permissions needed to install and manage Exchange 2010

  • Requirements for directory servers, hardware, software, clients, and other elements, including:

    • Windows Server 2008 Service Pack 2 (SP2) or later or Windows Server 2008 R2 operating system prerequisites that are required for all Exchange 2010 server roles
  • Language selection options in Setup and the specific languages that are supported for Exchange 2010

  • The Exchange Management Shell, the command-line interface for Exchange 2010, and the Exchange Management Console, the GUI

    Note

    Before installing Exchange 2010, we recommend that you install any critical or recommended updates from Microsoft Update.

Exchange Pre-Deployment Analyzer

You can use the Exchange Pre-Deployment Analyzer (ExPDA) to perform an overall topology readiness scan of your environment. This scan focuses on overall topology readiness and not the ability to run Exchange 2010 on the local computer. ExPDA provides a detailed report that will alert you if there are any issues within your organization, which could prevent you from deploying Exchange 2010. For example, ExPDA will notify you if you haven't deployed the minimum required Exchange service pack on all your Exchange servers. If your organization passes the ExPDA readiness scan, you can go ahead and use the Exchange Deployment Assistant.

To get ExPDA from the Microsoft Download Center, see: Exchange Pre-Deployment Analyzer

Permissions to Install and Manage Exchange 2010

Exchange 2010 requires different permissions to install and to manage your server roles. When you're installing Exchange 2010 servers in your organization, the account you use might not be the same account that you use for administering and managing your server roles. To manage your server roles, Exchange 2010 uses the Role Based Access Control (RBAC) permissions model.

Exchange 2010 uses RBAC to manage permissions on the Mailbox, Hub Transport, Unified Messaging, and Client Access server roles. With RBAC, you can control what resources administrators can configure and what features users can access. The RBAC model in Exchange 2010 is flexible and provides you with several ways to customize the default permissions.

RBAC has two primary ways of assigning permissions to users in your organization, depending on whether the user is an administrator or specialist user, or an end-user: management role groups and management role assignment policies. Each method associates users with the permissions they need to perform their jobs. The following tables list the tasks found in the Deployment Assistant and the permissions required to complete the task.

Note

Some features may require that you have local administrator permissions on the server you want to manage. To manage these features, you must be a member of the Local Administrators group on that server.

Installation permissions

The table below lists the permissions that you need to successfully use the Deployment Assistant tool and to install Exchange 2010.

By default, the account that's used to install Exchange 2010 in the organization is added as a member of the Organization Management role group.

When you install the first Exchange 2010 server role (Client Access) into your Exchange 2003 organization, Exchange Setup will prepare your Active Directory schema if you have the correct permissions. If you want to separate your Active Directory schema preparation from the Client Access server installation, see: Prepare Active Directory and Domains

An Exchange 2010 SP2 language pack contains the necessary resources for a supported Exchange language. Language packs are installed automatically during deployment of Exchange 2010 SP2. Client and server language packs come grouped into a single bundle containing both client and server resource and support files. There are no performance issues with installing all the languages because they're just stored when not in use.

Exchange Management Shell

The Exchange Management Shell, built on Windows PowerShell technology, provides a powerful command-line interface for Microsoft Exchange 2010 that enables automation of administrative tasks.

With the Shell, you can manage every aspect of Exchange 2010; the Shell can perform every task that can be performed by the Exchange Management Console and the Exchange Control Panel in addition to tasks that can't be performed in those interfaces. In fact, when a task is performed in the Console or the Control Panel, those interfaces use the Shell to perform the task.

Exchange Management Console

The Exchange Management Console (EMC) is a Microsoft Management Console (MMC) 3.0-based tool that provides you with a GUI to manage the configuration of your Exchange 2010 organization. You can also add the EMC snap-in to custom MMC-based tools.
