Exchange 2010 to Exchange 2016 Migration

Introduction

In this blog series of Exchange 2010 to Exchange 2016 migration, we have worked on Exchange 2010 to 2016 migration planning, installed Exchange 2016 server and in previous article of this blog series, we have performed post installation tasks of Exchange 2016 Server and moved our mail flow and HTTPS traffic to Exchange 2016 server. In this part of the series we will move users mailboxes from Exchange 2010 to Exchange 2016.

We will not be working on decommissioning Exchange 2010 server and we do not have any public folder on Exchange 2010 that requires migration to Exchange 2016 server.

Migration of Mailbox to Exchange 2016 Server

Perform the following steps to migrate mailboxes from Exchange 2010 to Exchange 2016 server.

  • Login to Exchange Administrative Center with admin credentials
  • Navigate to Recipients > Migration
  • Click on icon and move to a different database

  • Under Select the users that you want to move, click Add Add Icon icon to add users or you can upload list of mailboxes using a CSV file

  • In the Select Mailbox window, select the mailboxes you want to move, and then click Add Icon icon to add and then OK.

  • Specify a name for the new mailbox move, Make sure you have selected the option to move both primary and archive mailbox. In case you do not have a archive mailbox you can skip that option.
  • Under Target database, click Browse and select the target database of Exchange 2016 Server.

  • Select the option to automatically start the migration batch to start the batch immediately. You can also unchecked the option and manually start the batch later on.
  • Plan for mailbox migration completion, you can select the option to automatically complete the migration batch. During the finalization phase, the mailbox will be unavailable for a small period of time. If you choose to manually complete the mailbox move, you can decide when the move is finalized and you can plan for batch completion in after hours to avoid end user interruption.

Once the migration is completed, the end user will receive a pop up message that states “Administrator has made a change that requires you to restart outlook client”. Once user restart the outlook client he will be connected with his mailbox on Exchange Server 2016.
