What is the Google Workspace to Microsoft 365 migration checklist?

This is a comprehensive 60-step checklist covering every phase of migrating from Google Workspace to Microsoft 365: pre-migration planning, data inventory, DNS preparation, the actual migration execution, and post-migration verification. It ensures no critical step is missed, from verifying domain ownership to updating SPF records after cutover.

How do I migrate Gmail to Outlook?

Gmail emails are migrated to Outlook (Exchange Online) using IMAP sync or a migration tool like BitTitan MigrationWiz. The process preserves folder structure, read/unread status, and timestamps. Calendar events migrate via ICS export/import or automated tools. Contacts export from Google as CSV and import into Outlook. We recommend using professional migration tools for mailboxes over 5GB.

Will Google Drive files transfer to OneDrive?

Yes. Google Drive files can be migrated to OneDrive using Microsoft's native migration tool, SharePoint Migration Manager, or third-party solutions. The process preserves folder structure, file permissions, and sharing links. For files over 250GB or complex sharing setups, professional migration services ensure nothing breaks. Google Docs, Sheets, and Slides convert to Office formats during migration.

How long does Google Workspace to Microsoft 365 migration take?

For businesses under 50 users, the migration typically completes in 1–3 days. For 50–200 users, expect 3–7 days. For enterprise deployments (200+ users), plan 1–3 weeks. Timeline depends on total data volume, internet bandwidth, and whether you use a staged or cutover approach. Pre-migration planning adds 3–5 days but dramatically reduces risk.

Do I need to update SPF records when migrating to Microsoft 365?

Yes — absolutely. Your SPF record must be updated to include Microsoft 365's mail servers (include:spf.protection.outlook.com) and remove references to Google's servers if you are fully migrating. DKIM must be reconfigured for your domain in the Microsoft 365 Security & Compliance center. DMARC policy should be reviewed and updated. Without these changes, your emails will fail authentication and land in spam.

Can I migrate Google Workspace to Microsoft 365 without downtime?

Yes. Use a staged migration approach where both systems run in parallel. Migrate data in the background while users continue using Google Workspace. Schedule the DNS cutover (MX record change) for off-hours. Users experience no interruption — they simply start using Outlook the next morning while all their data is already there.

Migrating from Google Workspace to Microsoft 365 is one of the most common requests we handle. It is also one of the most complex — not because the technology is difficult, but because there are so many moving parts: Gmail to Outlook, Google Drive to OneDrive, Google Calendar to Outlook Calendar, shared drives to SharePoint, and the dreaded DNS cutover.

This checklist covers 60+ steps across 6 phases, from initial planning through post-migration verification. Each step is actionable, specific, and based on real migration projects we have completed. Download the PDF version or work through the interactive checklist below.
