Develop a Test Plan for Your Domain Upgrade Process

Updated: November 19, 2009

Applies To: Windows Server 2008, Windows Server 2008 R2

It is important to develop a plan for testing your domain upgrade procedures throughout the upgrade process. Before you begin, test your existing domain controllers to ensure that they are functioning properly. Continue to test your domain controllers throughout the process to verify that Active Directory Domain Services (AD DS) replication is consistent and successful.

The following table lists the tools and log files to use in your test plan. For more information about installing tools to test domain controllers, see How to Administer Microsoft Windows Client and Server Computers Locally and Remotely (http://go.microsoft.com/fwlink/?LinkId=177813).
