Benefits of Migrating from Exchange to Office 365

To simplify business processes and better serve customers, organizations look at technology-driven productivity solutions that improve information sharing, improve teamwork, and decision-making. At the same time, IT leaders face the pressure to reduce IT costs, upgrade aging infrastructure, and reduce time to market while meeting the demands for improved compliance and security.

It is becoming increasingly difficult to keep your email server up-to-date while strengthening your security to avoid the risk of breaches. This is where migration service providers come and play an important step toward digital transformation and help to Migrate user from exchange to Office 365 for most organizations.

Things to consider before migrating

Migrating email to the cloud is complex and preparatory evaluations can significantly increase errors. Successful migration requires preparation. When you move to the cloud, it becomes easier to access the mailbox on an azure remote virtual desktop from anywhere. For that, you need to understand and assess your current infrastructure, review dependencies, estimate final cloud costs, adapt technical requirements to your migrated environment, and use automated assessment tools.

Understanding your current Exchange environment

The initial step is to prepare your on-premises Exchange for migration and complete your existing on-premises Exchange inventory. This includes the number of mailboxes, storage location, DNS, network configuration, client devices, operating system hosting the email system, and more.

Choosing the right migration:

Cutover Migration:

If you need to migrate from on-premises Exchange Server versions 2003, 2007, 2010, 2013, 2016, or 2019 to Office 365, we recommend cutover migration. This method may not work properly for large mailboxes and may take longer than necessary to complete the migration. You can use this method to migrate up to 2,000 mailboxes to Office 365, but Microsoft recommends a limit of 150. Performance suffers as the number increases. You can initiate a cutover migration from the Exchange admin center (EAC).

Staged Migration:

If you want to move mailboxes in stages or batches, we recommend gradual migration. You can move more than 2000 mailboxes, but it only works with Exchange 2003 and 2007 versions. Migrate mailboxes to Office 365, typically over weeks or months.

Hybrid migration: 

It allows you to move mailboxes in stages. Here, mailboxes are managed both on-premises and online and can be used to migrate 1502000 mailboxes from any Exchange version to Office 365. Suppose you have a version of Exchange Server (Exchange Server 2010 or later) supported by Microsoft that is part of Active Directory. In this case, the default option should be Exchange Hybrid Migration. This migration could eventually be an intermediate step towards migrating to Office 365.

IMAP Migration:

The IMAP migration type supports IMAP migration and allows you to move users from Gmail or other email systems. Get the information from the source mailbox and pass it to Office 365. You can migrate mailboxes using the Exchange admin center or PowerShell. However, calendar entries, tasks, and contacts all remain in your original inbox and must be manually migrated by the user. The total number of mailboxes is 50,000 and the item limit is 5,000,000.
