Microsoft Exchange Server 2019 is the latest on-premises version. It offers better security, improved performance, and an easier structure compared to Exchange 2016. Many organizations upgrade to Exchange 2019 to stay supported and gain access to new features. However, migrating from Exchange 2016 to 2019 requires careful planning to prevent downtime or data loss. In this blog, we will discuss how to migrate from Exchange 2016 to 2019 using both the manual method and the Shoviv Exchange Migration Tool.

Why Migrate from Exchange 2016 to Exchange 2019?

Upgrading to Exchange 2019 has several benefits for businesses. Exchange 2019 works with modern hardware, has better security features, and improves search performance. It also simplifies management by combining Mailbox and Client Access roles into one role. Additionally, Microsoft has ended support for Exchange 2016, making migration crucial for ongoing stability and compliance.


Pre-Migration Requirements

Before starting the migration, ensure the following requirements are met:

* Exchange 2016 must run on a supported Windows Server version
* Active Directory schema should be healthy and updated
* Install necessary cumulative updates (CU) on Exchange 2016
* Backup all Exchange mailboxes and databases
* Check for enough disk space and system resources
Proper preparation helps reduce the chances of migration failure and data problems.

 Manual Method to Migrate Exchange 2016 to Exchange 2019

The manual migration involves installing Exchange 2019 and moving mailboxes from Exchange 2016. This method is best for admins with strong technical skills.
Step 1: Prepare Active Directory
Run the Exchange 2019 schema update commands using setup.exe. This prepares Active Directory for the new Exchange version.
Step 2: Install Exchange Server 2019
Install Exchange 2019 on a new server. Make sure all necessary Windows components and .NET Framework versions are set up before the installation.
Step 3: Configure Exchange 2019
After installation, set up virtual directories, certificates, and mail flow settings. Check that Exchange 2019 works correctly with Exchange 2016.
Step 4: Move Mailboxes
Use the Exchange Admin Center (EAC) or PowerShell to transfer mailboxes from Exchange 2016 to Exchange 2019. Monitor the migration batches until they finish.
Step 5: Decommission Exchange 2016
After moving all mailboxes and services, you can safely uninstall Exchange 2016.
Limitations of Manual Method
* Complex and time-consuming process
* Requires advanced Exchange skills
* High risk of human error
* No straightforward way to migrate public folders or archive mailboxes
