Like Exchange 2007 Service Pack 1, Exchange 2007 Service Pack 2 is a slip-streamed version.

Exchange 2007 Service Pack 2 introduces several new features, but in order to utilize Exchange 2007 SP2, you must perform the following steps:

1. Extend the Schema
2. Prepare Active Directory
3. Install Windows Installer 4.5
4. Uninstall Interim Updates

Extend the Schema

In order to deploy Exchange 2007 SP2, you must first extend the schema. Depending on your environment's configuration, one of the following scenarios will happen:

• If your Active Directory environment currently does not have any Exchange Server version deployed, then when you extend the schema, the schema changes included with Exchange 2000 through Exchange 2010 will be deployed in your environment.
• If your Active Directory environment is currently Exchange 2000 and you are upgrading to Exchange 2007, then when you extend the schema, the schema changes included with Exchange 2003 through Exchange 2010 will be deployed in your environment.
• If your Active Directory environment is currently Exchange 2003 and you are upgrading to Exchange 2007, then when you extend the schema, the schema changes included with Exchange 2007 through Exchange 2010 will be deployed in your environment.
• If your Active Directory environment is currently Exchange 2007 and you are upgrading to Exchange 2007 SP2, then when you extend the schema, the Exchange 2010 schema changes will be deployed in your environment.
