Google Workspace Migration Services: Vendor Selection and Cost Guide for Businesses

Google Workspace Migration Services allow minimal downtime options to migrate data, such as emails, calendars, and contacts, along with collaboration information, from various applications (Microsoft 365, Exchange, IMAP, Dropbox, Box, etc.) to Google Workspace. Migration Services also allow the transfer of business data from one Google Workspace tenant to another. Appropriate vendors will offer migration planning, customer-selectable tools, data mapping, security setup, and pilot testing, as well as cutover support. User training and support are also included, but only after migration is completed. 

Many standard workloads can be managed with the migration tools that Google has developed. As an example, the latest Google Data Migration Service has the ability to migrate emails from Google Workspace, Exchange Online, and IMAP and Gmail. The service can also transfer business files from OneDrive to My Drive via the Admin console. 

Quick Answer 

Google Workspace Migration Services will often include a discovery meeting, migration of emails, calendar and contacts, and a transfer of Drive/OneDrive contents. They will also include DNS cutover, security setup, and support with the user training included. Typical variable costs will depend on user count, source platform, data size, and migration tool. Other costs related to business operations may be incurred for a basic migration of business emails, or a comprehensive migration of business collaboration tools. 

Google Workspace Migration Services should be selected by complexity of workload (standard vs specialised) rather than cost. Examples of a standard workload would be the migration of 20 users from Gmail. A specialised workload would be the migration of 500 users from Microsoft 365 to Google Workspace, which would include discovery, pilot testing, permission mapping, and change management. A rollback plan for the migration would also be required. 

Key Takeaways 

• 1. Google Workspace migration cost depends on users, data volume, source system, and complexity. 

• 2. Built-in Google tools are useful for standard migrations, but complex projects often need specialists. 

• 3. The cheapest vendor is risky if they skip discovery, testing, or permission validation. 

• 4. Ask for a fixed scope, migration runbook, pilot plan, support window, and post-migration checklist. 

• 5. Budget separately for Google Workspace licenses, migration tools, professional services, training, and support. 

What Are Google Workspace Migration Services? 

Google Workspace migration services facilitate the transfer of business communications and collaboration data to Google Workspace and aim to minimise downtime as well as reduce data loss, permission issues, and user disruptions. 

Some of the following services may be offered as part of a migration service: 

• 1. Migration of email to Gmail. 

• 2. Migration of calendar and contacts. 

• 3. Migration from Microsoft 365 to Google Workspace. 

• 4. Migration from Exchange to Google Workspace. 

• 5. Migration from IMAP to Gmail. 

• 6. Migration from OneDrive to Google Drive. 

• 7. Migration of SharePoint to Google Drive or Google Shared Drives. 

• 8. Migration of Dropbox, Box, or file servers. 

• 9. Google Workspace tenant-to-tenant migration. 

• 10. DNS, MX, SPF, DKIM, and DMARC setup. 

• 11. Google Admin console setup. 

• 12. User onboarding. 

• 13. User training. 

Definition: Google Workspace migration is the migration of business users, email, files, calendars, contacts, permissions, and collaboration workflows to Google Workspace. 

What Data Can Be Migrated? 

Most Google Workspace migrations cover data related to email, calendars, contacts, files, folders, users, groups, and collaboration, though coverage is dependent on the source platform and the migration tool. 

Google Workspace Migrate supports Microsoft Exchange, SharePoint or OneDrive, file share systems, Box, and Google Workspace, and can run on Microsoft Windows machines, whether they are on-premises or in the cloud. 

Step-by-Step Google Workspace Migration Process 

There are eight steps to completing a migration within Google Workspace: discover, clean, map, pilot, migrate, cutover, validate, and support. 

Step 1: Discovery 

Begin with an assessment of users, groups, third-party integrations, mailboxes, and more. 

When conducting a discovery audit, consider: 

• 1. Inactive vs. active users 

• 2. User mailbox sizes 

• 3. Shared mailboxes 

• 4. Delegated calendars 

• 5. Shared drives 

• 6. Files on OneDrive, SharePoint, Dropbox, file servers, etc. 

• 7. External sharing policies 

• 8. Retention policies, legal holds, and compliance requirements 

• 9. Current authentication and email routing policies 

Step 2: Scoping and Pricing 

Define a migration scope in preparation to receive final quotes. 

Consider: 

• 1. Source system 

• 2. User count 

• 3. Data volume 

• 4. Workloads 

• 5. Cutover details 

• 6. Acceptable downtime 

• 7. Training

• 8. Support 

Step 3: Provision Google Workspace 

Prep the destination system before entering data. 

• 1. Domain verification 

• 2. User and group creation 

• 3. Org unit configuration 

• 4. Admin and security role assignments 

• 5. Google Drive sharing configuration 

• 6. Google Vault retention 

• 7. SPF, DKIM, DMARC prep 

Step 4: Pilot Migration 

Pilot migrations help assess systems for quality and performance. 

A good pilot migration includes: 

• 1. 5 to 10 users 

• 2. A user with a large mailbox 

• 3. An executive user 

• 4. A shared mailbox or team folder 

• 5. External sharing 

Step 5: Migration 

System migrations are conducted in batches to reduce overall migration risk. 

Common batching strategies include: 

• 1. Department migrations 

• 2. User location groups 

• 3. VIP users (first or last) 

• 4. Low-risk users (first) 

• 5. High-volume users (separate) 

Step 6: DNS Cutover 

Once the DNS cutover is complete, Google Workspace becomes the system of record for email. 

Standard DNS adjustments: 

• 1. MX records to accommodate Gmail 

• 2. Updates to SPF 

• 3. Signing of DKIM 

• 4. Review of DMARC policies 

• 5. Modifications to Autodiscover or the mail client as required 

Step 7: Validation 

Validation checks the email and calendar function post-migration. 

Confirm: 

• 1. Folders and their hierarchy 

• 2. Calendar appointments 

• 3. Contacts 

• 4. Ownership of files 

• 5. Shared Drive 

• 6. External sharing 

• 7. Device access 

• 8. Email 

• 9. Gmail functions 

• 10. Meet, Chat, Drive 

Step 8: Post-Migration Support 

Support should cover user issues, missing data, permission errors, mobile setup, Gmail training, and admin handover. 

A good support window is usually: 

• 1. 3–5 days for small migrations 

• 2. 7–14 days for mid-size migrations 

• 3. 30 days for enterprise migrations 

Benefits of Google Workspace Migration Services 

Google Workspace migration services reduce operational risk and help users adopt Gmail, Drive, Meet, Chat, Docs, Sheets, and Slides faster. 

Key benefits: 

• 1. Lower downtime during email cutover 

• 2. Reduced data loss risk 

• 3. Better permission mapping 

• 4. Faster migration execution 

• 5. Better security configuration 

• 6. Improved user adoption 

• 7. Cleaner admin setup 

• 8. Better compliance planning 

• 9. Less pressure on internal IT teams 

Google Workspace provides all the business-grade email, storage, and collaboration services along with Google Drive, Google Meet, and built-in security features. Google touts the integrated business email services of Gmail as having spam and phishing protections that block 99.9% of threats.  

Limitations of Google Workspace Migration Services 

Migration services cannot address all types of issues on their own, particularly those that involve problematic legacy environments, messy permissions, duplicate data, legacy archives, or ambiguous ownership. 

Here are some of the frequent constraints: 

• 1. Migration may result in incomplete metadata. 

• 2. SharePoint permissions may need to be re-architected. 

• 3. Migration may require additional time for large mailboxes. 

• 4. PST archives can introduce additional migration burdens. 

• 5. Older applications may become reliant on the newer Microsoft 365 applications. 

• 6. Gmail and Drive require user training. 

• 7. Compliance and governance may require dedicated archived solutions. 

Common Mistakes 

Attributing the failure of your Google Workspace migration to your selection of an affordable vendor is inaccurate. Price alone is not the most important vendor criterion; rather, you need to understand each vendor's migration-related policies and services. The biggest vendor-related migration failure factor is the vendor's migration-related policies and services. 

Don't fall victim to the most common migration blunders, such as: 

• 1. Migrating without Data Cleanup 

• 2. Not Deactivating Inactive Accounts 

• 3. Ignoring Test to Validate Calendar Migration 

• 4. Overlooking DNS Implementation 

• 5. Forgetting about SPF, DKIM, DMARC 

• 6. Not Checking SHARED FILE Permissions 

• 7. Migrating without Pilot Migration 

• 8. Not Preparing Help Desk Scripts 

• 9. Assuming SharePoint = Drive 

• 10. Not Defining Rollback Procedures 

Best Practices 

The most successful Google Workspace migration projects are planned with an emphasis on business continuity rather than merely outlining the technical side of the data migration process. 

To include the best practices in a Google Workspace migration project, the following should be done: 

• 1. Conduct a pre-audit. 

• 2. Eliminate inactive accounts and data. 

• 3. Execute a trial migration. 

• 4. Migrate data in phases. 

• 5. Establish an accurate cutover runbook. 

• 6. Verify the data for every migration phase. 

• 7. Establish a contingency plan. 

• 8. Implement training for users prior to the system going live. 

• 9. Continually monitor the volume of support requests following the migration. 

• 10. Complete documentation to capture the settings of the last administration. 

Expert Tips 

Good vendors will test your migration scope before quoting moving everything is almost always slower, more expensive, and less beneficial than moving the optimal data. 

Practical tips: 

• 1. Do not pay for active licenses just to migrate inactive employee mailboxes. 

• 2. Team members should be able to access currently used data without being able to access older data. Old data can be archived. 

• 3. Transform file shares to be department-based as Shared Drives. 

• 4. Migrated files should never be shared with individuals, but should be shared with groups. 

• 5. Test the migrated files with the Executives and Finance staff first. 

• 6. Migration cutover should be completed outside the normal work schedule. 

• 7. Users should still be able to access the legacy system for some time after the migration is completed. 

• 8. Gmail and Outlook structures are inherently different. Users should be trained to see labels as Gmail folders. 

Real-World Examples 

Example 1: Small Business Email Migration 

For businesses with 25 employees migrating IMAP to Google Workspace, we recommend email migration, DNS cutover, Gmail provisioning, and introductory user training. The process should be straightforward given the absence of intricate migration of calendars, archives, or file servers. 

The biggest migration risk is poor discovery; if mailbox sizes, file ownership, permissions, and legacy systems are not examined at the outset, migration services can be delayed, and data may be irretrievably lost. 

7. Should we migrate all old data? 

Most companies find a migration of all legacy data cost-prohibitive and overly complex; therefore, migrating only data that is actively used and conducting an archive of the rest is common. 

8. How do I choose a Google Workspace migration vendor? 

Look for a vendor that has experience, understands the tools, has transparent pricing, has security controls and support, and can run a pilot and provide documentation for the migration. 

9. Is it possible to move from SharePoint to Google Drives? 

It is possible to migrate from SharePoint to Google Drive, but because the structures of SharePoint and Google Drive do not align, you would have to do a redesign to use Shared Drives. 

10. What do you do after you have migrated? 

Once you migrate, you have to validate your data, monitor for issues, check your security settings, train your users, update your documents, and carefully shut down the older systems.

Conclusion 

Google Workspace migration services encompass more than transferring emails. Well-planned migration ensures the risk to the business is minimised, data is preserved, permissions are designed and placed strategically, the environment is secured, and users are trained and encouraged to utilise Gmail, Drive, Meet, Chat, Docs, Sheets, and Slides. 

Trustworthy vendors will include elements such as migration scope, estimation of costs, an initial migration plan, and strategies for the migration, including a cutover plan, a validation checklist, and plans for support after the migration.
