How to Migrate from Exchange Online to Google Workspace?

Businesses are increasingly moving their email platforms to improve collaboration, reduce costs, and simplify administration. One of the most common transitions organizations make today is migrating from Exchange Online to Google Workspace.

Exchange Online, part of Microsoft 365, offers enterprise-grade email services. However, many companies prefer Google Workspace due to its seamless collaboration tools like Gmail, Google Drive, Google Meet, and Google Docs.

If your organization is planning to switch platforms, this guide explains how to migrate from Exchange Online to Google Workspace, the available methods, and how to perform a smooth and secure migration.

Why Migrate from Exchange Online to Google Workspace?

Before performing migration, it is important to understand why organizations switch from Microsoft’s ecosystem to Google’s platform. Below are the reasons that you can move.

Google Workspace provides real-time collaboration through tools like Google Docs, Sheets, Slides, and Drive. Multiple users can edit documents simultaneously without version conflicts.
Google Workspace has a simple interface that reduces the learning curve for new users. Gmail’s interface is intuitive compared to traditional Outlook mailboxes.
Google Workspace is designed primarily for cloud environments, making it easier for distributed teams to access files and communication tools from anywhere.
Unlike Exchange environments that often require administrative oversight, Google Workspace simplifies administration with centralized controls.
Google Workspace allows organizations to scale their email infrastructure easily without complex server configurations.

What Data Can Be Migrated from Exchange Online to Google Workspace?

When performing migration, the following mailbox data can typically be transferred:

Emails and attachments
Contacts
Calendars
Mailbox folders
Archive mailboxes
Metadata (date, sender, recipient, etc.)

Ensuring that this data is migrated correctly is critical to maintaining business continuity.

Methods to Migrate Exchange Online to Google Workspace

There are two common approaches organizations use to migrate their email data.

Manual Migration Method
Automated Migration Tool

Let’s examine each approach.

Method 1: Manual Migration from Exchange Online to Google Workspace

Google provides built-in migration utilities that allow administrators to move mailboxes from Exchange environments. But this is a lengthy process. For easy understanding, I have divided the steps.

Step 1: Prepare Google Workspace for Migration

Before starting the migration process:

Sign in to Google Admin Console
Verify your domain in Google Workspace
Create user accounts for all employees
Assign Gmail licenses

This ensures the destination environment is ready to receive migrated mailboxes.

Step 2: Enable Exchange Web Services (EWS)

Migration requires Exchange Web Services to access mailbox data.

Sign in to Microsoft 365 Admin Center.
Open Exchange Admin Center.
Enable Exchange Web Services (EWS) for user mailboxes

This allows Google Workspace migration tools to connect to Exchange Online.

Step 3: Configure Data Migration Service

Google Workspace offers a Data Migration Service to move emails.

Go to Admin Console.
Navigate to Data Migration.
Select Exchange Online as the source server
Enter administrator credentials
Provide the EWS endpoint

Step 4: Map User Accounts

Next, map Exchange Online users to their respective Google Workspace accounts.

Example: make Exchange Online and Google Workspace as headers and add your source ID in the Exchange Online column and the destination column in Google Workspace.

Correct mapping ensures each mailbox is migrated to the right destination.

Step 5: Start the Migration

After configuration:

Select mailboxes to migrate.
Start migration.
Monitor migration progress in the Admin Console.

Depending on mailbox size and internet speed, migration can take several hours or days.

Limitations of Manual Migration

Although manual migration is possible, it has several drawbacks.

Limited control over the migration process
Risk of incomplete mailbox transfer
Time-consuming for large organizations
Requires technical expertise
Limited migration of mailbox components

Because of these limitations, many organizations prefer using professional migration software.
