by Carter Toni

DMARC Office 365Both Google Workspace and Microsoft 365 are popular cloud collaboration tools for businesses. If you’ve decided that Microsoft 365 is a better fit for your team, concerns about the migration process may be holding you back. Once you’ve decided to Migrate Google Workspace to Office 365, the first step is choosing whether to use a manual process, an automated process, or a third-party migration tool.

Let’s go step by step for manual Office 365 Migration:

1. Check for the permissions

To complete the migration process, you must be assigned as a project creator in Google Workspace and logged in with those credentials.

2. Creating an email subdomain:

Set up email subdomains that are routed to both Google and Microsoft accounts. The subdomain must be the same for both accounts and must be a subdomain of your website’s primary domain. To do this, log into your Google Workspace admin page and select Add domain. Add the domains of your choice to route email to Microsoft 365, then click Add domains and start verification. Don’t forget to enable DMARC Office 365 as an additional layer of protection.

3. Prepare your Google Workspace account

To ensure the success of your Google Workspace account migration, make sure to have it all set up properly. First, log into your administrator account and create a service account. Create a project and select Enable domain-wide G Suite delegation. Next, enable APIs for Gmail, Google Calendar, Contacts, and People. Next, you need to grant your Google tenant access to your new service account. To do this, select Manage security, API controls, and domain-wide delegation. Click Add new API client and add the client ID of your service account. List all required scope information in the OAuth scopes row and click Authorize.

4. Add migration batch

Sign into the new Microsoft 365 EAC. Click Migrations and click Add Migration Batch. On this page, you need to name each batch and select migration to Exchange Online as the mailbox migration path. Click Done when finished. Next, you need to select the type of migration from the dropdown menu. Select Migrate Google Workspace (Gmail) and click Next.

5. Configure migration endpoints

After creating a migration batch, the migration wizard displays the Migration Endpoint Settings page. If this is the first migration process for your organization’s accounts, you should select Create a new migration endpoint. Enter the name of the target endpoint and decide if the default settings for maximum concurrent migrations and incremental synchronizations should be adjusted. Then click Next.

This will take you to the Gmail migration configuration page. Add the email address linked to your Google Workspace account. Then click Import JSON and follow the prompts to locate and open the downloaded JSON file.

6. Add mailboxes to the CSV file

Now you need to create her CSV file listing all the users to be migrated. The header of this file should contain the primary email address of your existing Microsoft 365 mailbox. You can also specify a username that includes your Gmail address.

7. Plan your migration

At this point, the Move configuration page is displayed. Enter the requested information and click Next. On the schedule page, review all the information you entered and click Save. After that, Select the migration batch you are working on and go to the details pane. Select the appropriate options and click Save. The batch status should change to Completed and users should receive all emails sent to their old Gmail address to their new Microsoft address.

Also, when you choose Microsoft 365, you also take advantage of Virtual Desktop Hosting provided by them to maximize the security of remote working.
