Checklist: Upgrading from Exchange 2003

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

Use this checklist to upgrade from Microsoft Exchange Server 2003 to Exchange Server 2010. Before you start working with this checklist, make sure you're familiar with the concepts discussed in:

• Planning for Exchange 2010

• Deployment Security Checklist

• Exchange 2003 - Planning Roadmap for Upgrade and Coexistence

This checklist is generic in that it provides guidance for a typical upgrade scenario. For more customized step-by-step guidance about how to upgrade your Exchange 2003 organization, see the Exchange Server Deployment Assistant.

Exchange Server 2010 introduces the Exchange Server Deployment Assistant, or ExDeploy, a new Web-based tool that can help you with your Exchange deployment. ExDeploy asks you a few questions about your current environment and then generates a custom checklist and procedures that help simplify your deployment.

For more information, see Exchange Server Deployment Assistant.
