Moving from Exchange Server 2019 to Microsoft 365 is a smart choice for organizations looking to improve scalability, security, and accessibility. Office 365 provides cloud features, lower maintenance costs, and collaboration tools that make it popular among modern businesses. However, a migration project needs careful planning, proper execution, and the right tools to prevent downtime or data loss. This guide outlines the process to migrate mailboxes from Exchange Server 2019 to Microsoft 365 and presents an alternative method to ensure a smoother experience.
Process to Migrate Mailboxes from Exchange Server 2019 to Microsoft 365
You can migrate Exchange 2019 to Office 365 using the Hybrid Migration method, which is commonly used in medium to large environments. This method allows coexistence between on-premise Exchange and Office 365 for a smooth transition.
1. Prepare the Environment
First, make sure your Exchange Server 2019 and Active Directory are healthy. Install the latest updates and check your DNS settings. Next, verify your domain in Microsoft 365 and add the necessary TXT records. Also, set up Azure AD Connect to synchronize on-premise users with Office 365.
2. Set Up Hybrid Configuration
Use the Hybrid Configuration Wizard (HCW) from Microsoft. This tool simplifies the process of creating a secure connection between Exchange 2019 and Office 365. It handles mail flow, EWS settings, OAuth authentication, and other needed services.
3. Create Migration Batches
After configuring hybrid, go to the Microsoft 365 admin center and access the Exchange Admin Center (EAC). Create migration batches to move mailboxes. You can select users from Active Directory or filtered groups. The batch migration allows you to move multiple mailboxes with continuous syncing.
4. Complete the Migration Batch
Once mailbox data is synced, complete the migration batch. Users will switch to Office 365 with minimal downtime. Ensure that Outlook clients are updated and Autodiscover points correctly to Office 365.
5. Update DNS Records
To finish the migration, update your MX, SPF, and Autodiscover records to point to Office 365. This change ensures new emails go straight to Exchange Online.
