How to Migrate Exchange 2013 to Office 365? Some Methods 

There are several methods that can be used for Exchange 2013 migration. Here we will discuss two of those methods: Cutover Migration and Hybrid Migration. These methods also hold certain shortcomings in their working as well.

Also, Exchange Server 2013 migration is a tiresome process, but to make it more smooth organizations are advised to make use of professional-grade migration software.

Let’s start with the processes.

Cutover Migration to Migrate Exchange 2013 to Office 365 Step-by-Step

A cutover migration is performed using the EAC(Exchange Admin Center). This type of migration facilitates the export of mailboxes in one go which makes the process much less tiresome. 

But the process of Cutover migration is only applicable for only certain versions of the Exchange server, namely Exchange Server 2003, 2007, 2010, and 2013.

How to migrate from Exchange Server 2013 to Office 365 Using EAC?

  • Start the planning for Cutover migration and choose the Workload.
  • Owner credentials are required for domain verification.
  • Make cutover batches for mailbox migration. 
  • These Cutover batches are used to migrate Exchange 2013 to Office 365
  • Reroute the emails to Office 365.
  • Verify the completion of the migration procedure. Delete the cutover batches.
  • Purchase the required Office 365 licenses for the migrated users.

The process of Cutover migration has a lot of shortcomings. Some are listed below:

  • There is a limit to the number of users that can be migrated in a single attempt. The limit is 2000.
  • This process will be hard to perform for users with less technological understanding. Also, the users have to be familiar with the functionalities of the Exchange Admin Center.
  • This process consumes a lot of time to migrate Exchange 2013 to Office 365. If the amount of data is huge, the migration process can take days or even weeks.

Note: Cutover migration is not the suggested method for a large number of user accounts. Microsoft itself has recommended that users choose this method when the number of user accounts is less than 150.

Hybrid Migration to Migrate Exchange 2013 to Office 365 Step-by-Step

This process uses Azure AD Connect for migration. First, the user has to set up the Directory Synchronization to perform the migration. This process proves to be significantly more complex than any other migration process like Staged and Cutover migration.

Steps Using Azure AD Connect:

  • Verify the domain by clicking on Setup & Domain>>Add Domain.
  • Navigate to Setup & Data Migration. Choose Data Service and then click Exchange.
  • Input the required credentials and click on Update.
  • Map the users and provide the necessary Office 365 licenses.
  • Now. go to Setup and choose the Data Migration option.
  • Click on the Exchange option to start the process to migrate Exchange 2013 to Office 365 step by step. 

The limitations of Hybrid migration are very significant. Some of them are:

  • Hybrid migration is only supported by Exchange server version 2010 or higher. This process will not work unless the Exchange server version is updated to Exchange 2010 or above.
  • This process consumes a lot of time.
  • The chance of data loss is much higher in this process if anything goes unplanned.
  • The user has to follow the steps very closely.
