Pre-Migration Checklist for Easy Outlook Migration to Gmail

One overlooked step during Outlook to Gmail migration could lead to hours of troubleshooting—here’s how to avoid that with pre-migration analysis!

With proper preparation, migration can be smooth and hassle-free. Whether you’re an IT manager or a business professional leading the charge, a solid pre-migration checklist can prevent data and email loss and downtime and ensure a seamless transition to Gmail

Here’s a simple pre-migration checklist to ensure you’re ready before you hit the “migrate” button and your Outlook-to-Gmail transition goes off without a hitch.

1. Collect and Verify Admin Login Details

Before you start transferring emails from Outlook to Gmail, make sure your team has the admin login credentials for both Outlook and Gmail available to integrate both clouds into our migration web app.

• Credential Collection: Get the admin login credentials for both platforms and store them securely according to your organization’s security policies.
• Access Validation: Test the credentials ahead of time to avoid any login issues during the cloud authentication process.
• Permission Verification: Confirm that the admin accounts have the necessary permissions to access mailboxes, export data from Outlook, and import it into Gmail.

2. Assess Your Current Environment (Outlook)

When conducting a pre-migration assessment for migrating Outlook to Gmail, take a step back and evaluate what you have:

• Mailboxes: Create a list of all Outlook mailboxes that need to be migrated. This includes user mailboxes, shared mailboxes, distribution lists, and public folders.
• Data Volume: Determine the size of your mailboxes. This helps in planning storage needs and migration timelines.
• File Formats: Outlook uses PST files. Make sure you know where they are stored and that they are accessible.
• Critical Data: Identify emails, contacts, calendars and attachments that need to be migrated and filter out what’s not necessary to avoid data bloat.

3. Clean Up Your Inbox

Do you really need those 5-year-old newsletters and random spam emails? Probably not! Before you migrate, take some time to:

• Delete junk, spam, and unnecessary emails.
• Organize emails into folders (Gmail uses labels, so structure matters!).
• Archive old emails instead of moving everything.

CloudFuze’s Gmail migration tool can help you migrate only the important stuff—no need to carry over the clutter!

4. Get Your Gmail Environment Ready

Make sure your Gmail (or Google Workspace) environment is set up properly to avoid issues during the migration:

• Assign Licenses: Assign the right Google Workspace licenses to avoid service interruptions. Gmail’s Business Starter plan has 30GB per user, Business Standard has 2TB, and Business Plus has 5 TB.
• Configure Security: Turn on 2FA, set permissions, and check Gmail’s security and compliance settings according to your organization’s policies.
• Accurate User Mapping: Mapping users from Outlook to Gmail is key to success. We recommend the industry standard CSV mapping method, so you have full control over mapping customization.
• Organize Labels and Filters: This will map Outlook folders to Gmail labels.

5. Backup Outlook Data

When planning pre-migration analysis for Outlook to Gmail, make sure you have a full backup of your Outlook data. This will ensure all your emails, attachments, calendars, and contacts are safely stored in case of data loss or corruption during migration.

Always check the backups to ensure they are complete and not corrupted. Our migration solutions maintain data integrity and eliminate any potential risks during the transition.

6. Plan the Migration Approach

You must choose a specific migration method:

Google Workspace Migration Tool: Google has its own migration tools, such as Google Workspace Migration for Microsoft Outlook (GWMMO) and Google Workspace Migration for Exchange (GWMME), which are robust and work well. It supports PST imports but has a file size limit of 20 GB per PST file. It is not the best choice for large enterprises with thousands of users or large-scale migrations.

Professional Tools: There are many tools out there that can migrate emails, but CloudFuze offers one of the most advanced email migration tools, especially for SMBs and large-scale migrations. We support email, contacts, and calendar events and preserve metadata such as timestamps. Our tool can handle complex migrations and large data volumes (unlimited TBs and PBs).

7. Test the Migration (Pilot Migration)

A pilot run on small-scale data is essential to identify any issues:

• Migrate a Test Account: Migrate a small set of mailboxes or a test account to test your migration process.
• Check Data Integrity: Verify emails, attachments, calendars, and contacts migrate correctly without data loss or formatting issues and metadata (timestamps) are preserved.
• Monitor Performance: Watch transfer speeds and error logs to troubleshoot before the one-time migration.

At CloudFuze, we make it simple to perform test migrations that allow IT admins to test our email migration tool with a small set of mailboxes and several test accounts.

8. Communicate with the End Users

Communicate with your end users to reduce confusion and disruption:

• Notify Users: Let your team know about the migration schedule, and any changes to login procedures.
• Provide Training: Provide training and guidance on how to use Gmail effectively, including how to access migrated emails, set up signatures, and configure settings.
• Share with Users: Let users know where to go for help if they run into issues through IT support or online resources.
