How to Migrate Exchange 2003/2007 to Exchange 2016?

The phrase “Exchange Server Migration” appears to be considerably complex. It is complex and needs expert hands, yes, but there are ways to make the process less complicated if all the process steps are followed systematically. Exchange server migrations typically follow a set of standard procedures and pre-requisites with only slight modifications depending upon each individual setup. In this post we’re highlighting the steps to perform a clear and straightforward Exchange 2003 or 2007 to Exchange 2016 migration. And since we always give you something extra, we’ll suggest a super easy alternative to the lengthy process towards the end.

What you should know before starting

There are a number of things you should be aware of before you begin with the migration. Planning ahead for these helps reduce the chances of setback and hurdles at later stages.

• It is important to note that in-place upgrades of the Exchange server are not possible. For example, you can’t simply upgrade Exchange 2003 to Exchange 2016, or Exchange 2007 to Exchange 2016. The reason for this is that each major Exchange release greatly differs from the previous version in terms of server architecture and internal working. Therefore, testing everything for loopholes would become very tedious and nearly impossible. Hence, the only way to upgrade would be to completely migrate data and services from the old servers to the new ones.
• Standard migration procedures cannot migrate to a new version from legacy versions. For example, under normal circumstances, to migrate Exchange 2007 to 2016, you first need to upgrade to Exchange 2013 and then remove Exchange 2007 server before migrating to Exchange 2016. This is needed because Exchange Server 2016 and 2007 can’t coexist in the same AD forest. The whole process is lengthy and considerably complicated.

The above pointers will prove beneficial while performing the migration.

Migrating Exchange 2003/2007 to Exchange 2016

Manual Steps:

To resolve the Exchange migration issue, Microsoft recommends the following steps:

Step 1: Migrate Exchange 2007 to Exchange 2013

This step involves a series of steps including the deployment of Exchange 2013, migrating from Exchange 2007 to 2013, and finally decommissioning Exchange 2007. The exact series of steps should be:

1. Exchange 2013 Deployment
2. Configuring Digital Certificates
3. Exchange-related virtual directories’ configurations
4. Offline Address Book (OAB) Configuration
5. Moving Internet mail flow from Exchange 2007 to 2013
6. Moving Client Access from Exchange 2007 to 2013
7. Moving mailboxes from Exchange 2007 to 2013
8. Moving public folder data from Exchange 2013 to 2013

Step 2: Decommission Exchange 2007

The second step is to decommission Exchange Server 2007 that means you should completely remove Exchange 2007 from the server that no longer exists.

Step 3: Install Exchange 2016 in existing Exchange 2013 environment

During the above mentioned process, Microsoft recommends using its Exchange Server Deployment Assistant. The tool acts like a technical guide for Exchange deployment. It asks a few questions about your environment and then generates a step-wise check list for you to follow.

Automated Steps:

Such converted files can be opened within Outlook. or You can also export mailboxes directly to Live Exchange Server.
