How to Migrate Emails from Google Workspace to Microsoft 365

Migration of thousands of mailboxes from Google Workspace to Microsoft 365 goes beyond just migrating emails. Large enterprises with sensitive data have to ensure that their business continuity, data integrity, and compliance needs are met without disrupting users.

This is where CloudFuze steps in. Our migration tool, CloudFuze Migrate, allows organizations to easily migrate emails from Google Workspace to Microsoft 365 and transfer all the emails, contacts, calendars, attachments, and metadata without errors.

In this blog post, we will guide organizations through the entire process of email migration from Google Workspace (Gmail) to Microsoft 365 (Outlook) and how they can leverage CloudFuze to perform a successful and secure migration.

Reasons Why Enterprises Migrate Email from Google Workspace to Microsoft 365

Here are some of the reasons why organizations decide to migrate email from Google Workspace to Microsoft 365:

• Mergers and acquisitions
• Compliance requirements
• Workforce productivity decisions
• Regulatory mandates
• AI and Productivity Initiatives

Regardless of which motivates them to undertake the migration, the entire process remains the same and involves several stages.

The 5 Key Steps to Migrate Gmail to Office 365

1. Discovery and Analysis Before Migration

Before migrating even a single mailbox, you need to understand and pre-scan the environment you will be working in. In corporate environments, Google Workspace can contain undocumented shared mailboxes, Google Groups that act like distribution lists, Drive email threads, and delegated users whose delegation was set up many years back and has been poorly managed.

At CloudFuze, we use an intelligent, automated analytics engine to analyze your Google Workspace environment, providing you with comprehensive details about the type of mailboxes that exist, their sizes, delegation structures, and label hierarchy. This will provide your team with an understanding of the scope, timeframe, and migration waves needed.

Key outputs at this stage:

• Total number of mailboxes, by type (e.g., user, shared, and delegate)
• Data size for each mailbox and all of them combined
• Map of Google Groups to distribution lists
• List of all mailboxes on legal hold

2. Identity Mapping & Microsoft 365 Provisions

Google Workspace and Microsoft 365 have unique approaches to dealing with identities. Mappings should be clean for Gmail addresses, Google account UPNs, and Microsoft 365 UPNs, since email addresses may change during the migration.

Provisioning and licensing of all Microsoft 365 users prior to migration is essential. Lack of license information mid-way through migration remains the most common cause of delays in enterprise migration projects.

User mappings for CloudFuze migrations can be easily controlled and validated using our built-in mapping engine that supports one-to-one, many-to-one, and domain translation mappings.

3. Compliance, Retention, and Security Policies Configuration

This step is usually skipped, yet it’s the one responsible for the costliest errors after migration.

Before moving even one mailbox, the compliance team should verify that:

• Retention policies are identical to your Google Vault and any third-party archiving retention policy set up in Microsoft 365 Purview
• Legal holds on mailboxes are kept intact and preserved
• DLP policies are configured
• Your Microsoft 365 datacenter region meets your data residency requirements

The CloudFuze compliance preservation layer keeps hold status and retention metadata throughout the entire lifecycle of the migration process to ensure that compliant data migrates from Google to Microsoft 365 with the same governance posture.

4. Phased Migration Implementation Using Delta Sync

Enterprise migrations at scale requires a phased wave approach. Attempting to migrate all users simultaneously creates unmanageable risk and helpdesk overload.

Wave migration must be performed using the following sequence for a Google Workspace to Microsoft 365 migration:

• IT and technical team members first to test the process using an independent group of users
• A pilot team (10-20 members) comprising various roles that represent different mailboxes and device configurations
• Business units in order based on inter-dependencies and business calendar without migration during blackout periods
• Executive/VIP users last to get maximal white-glove treatment during the last phase of the process

CloudFuze’s delta migration engine continuously syncs changes between Google Workspace and Microsoft 365 throughout the migration period. This means that by the time a user’s cutover arrives, the vast majority of their historical email is already at the destination.

5. Cutover, Verification, and Decommission

Cutover is when MX records are modified to direct incoming emails to Microsoft 365 servers. The cutover will be performed by CloudFuze during a time when traffic is minimal, and the entire team will be ready for the migration.

Verification is done by CloudFuze through completion reports after cutover, which ensures that all data from migrated mailboxes is verified. Spot-checks are done by the IT team on some selected users before signing off on the migration wave.

Decommissioning of Google Workspaces is done after maintaining read-only access for a minimum of 30 days to give room for any anomalies that might arise after cutover.

What is Migrated

During a Google Workspace to Microsoft 365 email migration, the following features will be preserved and moved:
