As businesses grow and their needs evolve, migrating to more robust and integrated platforms becomes essential. Many organizations using G Suite (now Google Workspace) are transitioning to Microsoft 365 for its enterprise-level tools, security, and seamless productivity features. If you’re planning to know about how to migrate from G Suite to Microsoft 365, this blog will walk you through both the manual method and an automated alternative to ensure a smooth transition.
G Suite, now known as Google Workspace, is a suite of cloud-based productivity tools that includes Gmail, Google Drive, Docs, Sheets, Calendar, and more. It’s known for its collaboration features and web-based convenience.

Microsoft 365 (formerly Office 365) is a cloud-based platform that offers applications like Outlook, Word, Excel, Teams, SharePoint, and OneDrive. It combines traditional desktop apps with cloud services, offering better offline access and integration with Windows-based systems.

Reasons to Migrate from G Suite to Microsoft 365

• Better Integration with Microsoft Ecosystem – Seamless compatibility with Windows, Office apps, and Exchange.
• Advanced Email Management – Outlook offers powerful email organization, archiving, and rules.
• Offline Access – Full access to emails and documents without needing internet connectivity.
• Stronger Security & Compliance – Microsoft 365 provides enhanced security features and compliance tools for businesses.
• Business Continuity – Built-in tools for backup, recovery, and enterprise-grade support.

How to Migrate from G Suite to Microsoft 365 Manually

Microsoft offers a built-in migration option using the Exchange Admin Center. Here’s how it generally works –

• Verify your domain with Microsoft 365.

• Create mailboxes in Microsoft 365 for each user.
• Prepare a CSV file containing Gmail usernames and passwords.
