Automatic Solution: Aryson Office 365 Migration Tool 

Aryson Office 365 Migration Tool is the most reliable solution you can pick today to migrate Office 365 to Google Workspace. This software performs the migration process in no time, without losing any data or having it corrupted. This software offers you some additional features like Remove Duplicate, Save Mail without Attachment, and Free Up Server Space. Using the same utility, you can also export Office 365 to CSV. Now, just go through the step-by-step tutorial provided below. 

Quick Guide to Migrate Emails from Office 365 to Google Workspace in Bulk: 

  1. First, open the Aryson Office 365 Migration Tool on your PC.
  2. Then, log in to your Office 365 with valid credentials. 
  3. Now, you have to pick the mailbox you want to migrate and choose the backup option. 
  4. Next, you cross-check all Office 365 mailbox folders, pick them to migrate, and click Next
  5. Select the G Suite option from the email clients listed. 
  6. Adjust built-in features if you need, and hit the Convert button. 

However, this is the most suitable solution; you can proceed with the manual method if data loss and corruption are not your concern as well, and you are up for giving your long hours just for completing the migration process. 

Manual Migration of Office 365 to G Suite 

The manual method to migrate Office 365 emails to Google Workspace involves using the Google Admin Console and Exchange settings. While this approach is cost-free, it can be time-consuming, requires multiple technical steps, and may not be suitable for bulk migration. 

1. Prepare a List of Google Workspace (G Suite) Users or Migration

To start the migration process, you first need to prepare the list of users who will be migrated to Google Workspace.

  1. Firstly, log in to the Google Admin Console using your admin credentials.
  2. Then, from the dashboard, go to Directory > Users.
  3. Now, you have to simply click on the Add New User option.
  4. Fill in the details of your team member to create their account.
  5. Keep this in mind: this method creates one user at a time. You’ll need to carry out the same steps individually for all users.
  6. Another option is to import a CSV file that includes the full list of users you need to add to Google Workspace.

2. Configure Mail Delivery to Google Workspace

Now, you have to configure how emails will flow between Office 365 and Google Workspace.

  1. Enable dual delivery to ensure that every email received in Microsoft Exchange Online (Office 365) is also duplicated in Google Workspace.
  2. With this setup, mail will still reach Office 365, but a duplicate will be delivered into the G Suite mailbox.
  3. The best part—this method does not require changing MX Records at this stage.

3. Assign Required Roles in Office 365 Before Migration

Before starting the migration, certain roles must be assigned to ensure the process runs smoothly.

  1. Run the Microsoft 365 Admin Login page and log in with your credentials.
  2. Then, navigate to the Admin Center >> Security and Compliance >> Exchange.
  3. Go to the Permissions section.
  4. Now, open the Admin Roles page.
  5. After that, you have to click on the ‘+’ icon to add more roles and assign:
    1. View-Only Configuration
    2. Application Impersonation
  6. Next, just click on the Next option to save changes.
  7. Go back to Permissions > User Roles, and add your admin account using the ‘+’ icon.
  8. Make sure to include the admin account if you are migrating multiple mailboxes

Note: Wait for the changes to reflect before proceeding to the migration phase.

4. Now, let’s migrate Office 365 to Google Workspace.

This is the most crucial step of the migration process. So, you have to perform it carefully. 

  1. Log in again to the Google Admin Console.
  2. Move to Data Migration.
  3. Select Email as the category of data you want to migrate.
  4. Next, define the items you want to move, such as emails, contacts, or calendars. Then, click Continue.
  5. Fill in the required details in the fields provided and hit Connect.
  6. Once the connection is successfully established, configure whether to migrate extra items like deleted or junk emails.
  7. Click Select Users to proceed.
  8. Finally, map the users between Office 365 and Google Workspace.

The migration process will now begin. Depending on the size of your data, it may take some time to complete. Once finished, all your Office 365 data will be available inside Google Workspace.
