Businesses these days are realizing the benefits of migrating their on-premises mailboxes, data, communications, and email management solutions over to a cloud-based platform like Office 365. These types of platforms are valuable for businesses as they are user-friendly. Studies have repeatedly shown that a good many enterprises have moved a portion of their IT and data to cloud platforms. 80%+ of those using Office 365 are satisfied with the service. 

Office 365 is the safest platform in the world. Microsoft also provides several tools that help you avoid malware and prevent data loss.


Microsoft Exchange to Office 365 Migration steps:


  1. Choosing Correct Migration Method

It is important to determine which option best fits your needs for Office 365 Migration. Below mentioned are the different methods of migration you should use according to your business needs:

  • Cutover Migration method
  • Staged Migration
  • IMAP Migration
  • Hybrid Migration
  1. Office 365 Readiness Assessment

Before beginning to plan your Exchange mailbox migration, it’s important to meet a cloud readiness assessment. This phase is important to determine if your existing cloud desktop service infrastructure is ready to handle the great features of Office 365. 

This phase involves:

  • Selecting License
  • Directory Services
  • Identity Management
  • The ability of your network
  • Determining readiness of the clients
  • Compatibility
  1. Planning the Migration

This is an important step for the end-users and software consultant to map all the data and estimate how long it will take for everyone to move across. Office 365 Migration Advisor provides detailed strategies for server upgrades, backups, and downtime before you perform the migration. In addition, this step involves choosing the right tools for successful cloud migration. Considering there are so many users etc., the advisor will point out which tool to use depending on what edition of Exchange you’re on.


  1. Pilot Migration

If you’re migrating from a local Exchange server, we recommend running a pilot migration program. Pilot migrations are a way to add a few test mailboxes and migrate data from one system to another while checking your migration plan and seeing how it goes. This talk will cover how to perform a healthy pilot migration. You can duplicate a test mailbox with the type and amount of data that the original mailbox needs to measure accurate results. This program provides an opportunity to discover issues after migration.


  1. The Migration and its Types

Below are the types of Microsoft Exchange to Office 365 migration:

  • Minimal Hybrid Migration
  • Full Hybrid Migration
  • No-Hybrid Migration

With a seamless migration to Office 365, you won’t have to worry about your email going through a third party. It will straight-up go to the Exchange server and then be transferred over. Once you finish your migration, the rerouting further assures your messages will always go through this service provider. Rerouting your DNS can be helpful if you want to use Skype for Business, Outlook, or any of the other Office 365 apps.


  1. Maintenance and Support

To manage your new cloud environment, you must have a subscription for a comprehensive maintenance and support plan. This includes the management of users, security, troubleshooting, and assigning privilege permissions.

Thus, your migration process will be completed.



The increase in accessibility and usefulness of Microsoft’s cloud-based systems make it a must for businesses today. Projects, workflows, and communication networks can be handled without professional IT skills or knowledge.

You’ll need someone who understands the intricacies of migration to take care of your IT needs, and there’s no better fit than providers like Apps4Rent that also has the experience in SharePoint Online Tenant to Tenant Migration.
