Moving from Exchange 2003 to Exchange 2007 using a Transition Strategy

As you interact with Exchange 2007 during the process of moving from one version to the next version (Ex2k3 to Ex2k7 for example) several terms are quickly made apparent:

Transition - the Scenario in which you upgrade an existing Exchange Organization to Microsoft Exchange 2007.

Migration - the Scenario in which you upgrade to Exchange 2007 by migrating data from a non-Exchange Messaging System to Exchange 2007.

I have posted additional online resources for migrating from Lotus Domino 6.5 to Exchange 2007 Server at the following links:

       Resources for Migrating from Lotus Domino 6.5 to Microsoft Exchange 2007 Server

There are numerous resource becoming available to address how to follow a Transition Strategy.  A good starting point if you maintain an Exchange 2003 Messaging Infrastructure is the following Microsoft TechNet document:

       Upgrading to Exchange 2007

Excellent reference material for co-existing with Exchange 2003 and Exchange 2000 Servers are found in these documents:

       Co-existing with Exchange Server 2003 and Exchange 2000 Server

       Planning for Co-existence

       Best Practices for Transitioning an Exchange Organization

Additionally, there are a number of good reference articles that address use of the Exchange Command Shell (Powershell 1.0).  I have referenced a few of these Powershell Commands in prior Blog entries:

       PowerShell Commandlets for Mailbox Administration (Recipient Management)

       How to Change Logging Levels for Exchange Processes in Exchange 2007

       PowerShell Commandlets for Connector Configuration in Exchange 2007
