Exchange 2003 to Exchange 2010 Upgrade Checklist
Dec 30, 2013

I spend a lot of time helping answer questions for people, and one that has been asked recently seemed to be a good one to spend a few minutes on with you.

“What would the proper sequence be to be able to take an existing Exchange 2003 installation and  transform it into an Exchange 2010 solution?”

To that end, the checklist below will help you walk through the key steps, and will provide support for each step with the appropriate pointers to on-line help if needed.

I have also created a detailed step by step how to deployment guide that will walk you through each of the steps required to take your Exchange 2003 environment and transform it into a functional Exchange 2010 solution. You can either take a look at the additional posts on how to do this by section, as listed below, or you can download the full guide as a Microsoft Word document Exchange 2003 to Exchange 2010 Step by Step Deployment Guidance.

Section 1: Pre-requisite checks and installing the CAS Role ( Steps 1 – 5 )

Section 2: Installing and configuring the Hub Transport Role ( Steps 6 – 8 )

Section 3: Installing and configuring the Mailbox Server Role ( Steps 9 – 10 )

Section 4: Installing and configuring the Edge Transport Role ( Steps 11 – 13 )

Section 5: Moving Exchange 2003 mailboxes to Exchange 2010 ( Step 14 )

 

Checklist: Upgrading from Exchange 2003

 


 

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:

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.
