Know the Basics: Google Workspace & Microsoft 365

Google Workspace (formerly called G Suite) is a cloud service by Google. It includes tools like Gmail, Google Drive, Docs, Sheets, and Calendar. These tools help teams work together online from anywhere.

Microsoft 365 (earlier known as Office 365) is Microsoft’s set of tools that includes Outlook, OneDrive, Word, Excel, Teams, and more. It offers both online and desktop versions, which makes it great for office work and communication.

Both platforms help with email, file storage, teamwork, and more. But many businesses prefer Microsoft 365 for its strong security, better support for desktop apps, and advanced business features.

Reasons to Migrate from Google Workspace to Microsoft 365

Let’s explore why businesses make this switch and the best ways to do it without any data loss.

Microsoft 365 works smoothly with Office apps like Word, Excel, and Outlook.
Apart from that, it offers better admin control, data protection, and compliance tools.
Tools like Teams in Microsoft 365 make internal communication and meetings easier.
Microsoft 365 allows full access to documents and emails even without the internet.
Along with that, admins get deeper control over user data, sharing, and permissions.

How to Migrate Google Workspace to Office 365 Manually?

If you prefer a free method and have basic technical knowledge, you can manually migrate Google Workspace emails to Microsoft 365 using Microsoft’s built-in tools. However, this process mainly supports email migration only (not contacts, calendars, or Drive files).

Step 1: First, Enable IMAP in Google Workspace

First, sign in to the Google Admin Console.
Then, navigate to Apps >> Google Workspace >> Gmail>>User Settings.
After that, enable IMAP access for all user accounts.
Additionally, ask users to either allow less secure apps or generate app-specific passwords if 2-step verification is active.

Step 2: Then, Create User Accounts in Microsoft 365

Now, log in to your Microsoft 365 Admin Center.
Next, go to Users>>Active Users.
Then, create a mailbox for every user who will be part of the migration.

Step 3: Next, prepare a CSV file with user details

Open Excel or Notepad and enter the following details for each user: EmailAddress, UserName, and app-password.
Save the file in .csv format. This file helps Microsoft match Gmail accounts with Office 365 mailboxes.

Step 4: After that, Create a Migration Endpoint

In the Exchange Admin Center, go to Recipients >> Migration >> Migration Endpoints.
Thereafter, click + New and select IMAP as the migration type.
Use the following settings:

IMAP server: imap.gmail.com
Port: 993
Encryption: SSL

Step 5: Now, Start a New Migration Batch

Go to Recipients >> Migration >> + New Migration Batch.
Choose IMAP Migration, then upload the CSV file you created earlier.
Later, select the migration endpoint you just created.
Name the batch and click Start to begin the process.

Step 6: Monitor the Migration Process

Once the batch is active, you can track the progress in the Exchange Admin Center.
You’ll see the status of each user mailbox being migrated.
Now, wait until all mailboxes show “Synced” or “Completed“.

Step 7: Then, Update your DNS (MX) Records

Here, log in to your DNS provider’s panel.
Change your domain’s MX records to point to Microsoft 365.
It ensures that all new emails will go directly to Office 365 instead of Gmail.

Step 8: Finally, Complete Post-Migration Checks

Now, test mail sending and receiving in all migrated accounts.
After that, inform your users that the switch is complete.
Once confirmed, you can delete the migration batch from the admin center.

Challenges You May Face with Manual Migration

When you consider these points, you get that the manual method is best suited for small, low-risk migrations. Although it is not recommended when full data transfer or speed is your priority.
