Laying The Groundwork for Exchange 2010 Migration

The process of migrating ones existing exchange server (either 2003 or 2007) to exchange 2010 appears to be daunting and complex in nature, but with the appropriate assistance and approach, can be quite simple. Exchange 2010 migration is as effective and simple as long as the appropriate steps are taken to seamlessly plan, build, and test before migrating. What follows is a brief discussion on laying the groundwork for a 2010 server migration.

As is true with any substantial data or server alterations and upgrades, it is essential that a disaster recovery plan be in place before beginning any migration process. Ensuring that one’s environment is fully backed up before embarking upon an exchange 2010 migration is imperative to mitigate any negative impacts of a failure (mainly data loss).  In addition, every server environment will be unique, and a generic guide to exchange migration is only useful when understood in the context of one’s specific organizational needs.

Firstly, when undergoing the planning stages of an exchange 2010 migration, it is essential to collect any and all information regarding the existing server environment. When dealing with Exchange server 2007, many of the existing configurations will be similar in nature to exchange server 2010 due to the same server roles. However, when dealing with exchange server 2003 to exchange 2010 migration, more groundwork needs to be laid before reconfiguring. This guide will focus on exchange server 2007 to exchange server 2010 data and services migration, legacy exchange removal and configuration completion. Although 2007 and 2010 server environments are similar, the upgrade stems mainly from 2010 server environment features that include database availability groups and client access server arrays.

During the exchange 2010 migration process, there may be certain configuration items in one’s environment that will be more sensitive to migration and can impact how smooth a transition occurs. Changes that could offer stumbling blocks to smooth migration could be extant firewalls, mailbox storage quotas, server IP addresses, or network routing. No environment will have the same configuration in regards to aforementioned items among others. This is why any and all changes need impact analysis review in accordance with all configuration items before beginning the migration project. This involves verifying that the existing network environment is able to accommodate exchange server 2010 before downloading the software and tools.

To gather information about one’s current exchange server environment, many organizations will use an exchange profile analyzer. This tool enables the individual to gather information on the size and configuration of the data that needs to be migrated to 2010 format. It is recommended that any analysis be undertaken at a time when the server environment is not immediately needed, as depending on how large ones exchange databases are, the process could take some time. Once the analysis report is produced, information about where excess data can be deleted will allow for less strain on the migration process. Reducing the amount of data that will need to be migrated will vastly reduce the chances of a slow or rocky transition to the new server environment.

For the analysis of ones existing server environment as well as the exchange 2010 migration and completion, offers the proper software and expertise to offer a seamless transition with extensive customer support.
