Prerequisites

• Make sure that the functional level of your forest is at least Windows Server 2003, and that the schema master is running Windows Server 2003 with Service Pack 1 (SP1) or later.
• Windows Server 2008 R2 must be used for all servers running Exchange 2010 server roles or management tools.
• Exchange 2010 cannot coexist with any versions older than 2003.

The use of 64-bit Active Directory domain controllers increases directory service performance for Exchange 2010.

Upgrade process, Exchange 2003 to 2010;

You can only deploy Exchange 2010 in an Exchange 2003 organization that operates in native mode. Use Exchange System Manager to change the Exchange organization to native mode on an Exchange 2003 server, as follows:

1. Start Exchange System Manager. Click Start > Programs > Microsoft Exchange> System Manager.
2. Right-click the organization, and then click Properties.
3. Click the General tab, and then, under Change Operations Mode, click Change Mode. Click Yes if you are sure that you want to permanently switch the organization’s mode to native mode.
