Exchange Server 2010 brought some revolutionary technologies, features, and services when it was first introduced a decade ago.
It was intended to assist organizations and individuals to improve their work habits by changing the focus from communication to collaboration. With Exchange 2010, it was possible to be deployed both on-premises and on the cloud.
With the end of support for Microsoft Hosted Exchange 2010, businesses have to adopt new platforms. As of now, there are the options of Exchange 2016, Exchange 2019, and Office 365 available. While some organizations prefer to retain their on-premises platforms with Exchange 2016 or Exchange 2019, many prefer Exchange 2010 to Office 365 migration. This blog focuses on migrating from Exchange 2010 to the cloud-based Office 365.

Prerequisites for Exchange 2010 to Office 365 Migration
Exchange 2010 to Office 365 migration requires meticulous planning. Here are some of the considerations to be made for Exchange 2010 to Office 365 migration
Is Office 365 required?
How is Office 365 going to address the need of your organization? Besides, is it financially viable and what are its benefits? You will have to compare the cost of Office 365 with the on-premises options.
Changing DNS for Office 365
You have to confirm that you own the DNS before migrating to Office 365. This is needed to ensure that you can receive emails on the new mail IDs after the migration is complete.
Set up a password policy
The migration to Office 365 allows access from any device increasing the risk of hacks. Consequently, it is important to frame a password policy ahead of time.
You might want to retain some of the functions of the old mailbox like autocomplete file, signatures, and other customization. You must be in a position to restore these after migration completion.
Methods for Exchange 2010 to Office 365 Migration
There are 2 manual methods provided by Microsoft for Exchange 2010 to Office 365 migration.
Cutover migration method
The cutover migration method is similar to express migration. It is a technique that allows for the migration of up to 2000 mailboxes.

Hybrid migration method
The hybrid migration method provides the flexibility to maintain on-premises Exchange and Office 365 mailboxes. This method is more complex than the cutover migration. However, the advantage is that it supports over 150 mailbox migration without any third-party tool. However, you will have to enable directory synchronization.
