Comprehensive Google Workspace to Microsoft 365 Migration — Tasks, Forms & Sites Included
This service is a comprehensive, professionally tooled migration from Google Workspace (formerly G Suite) to Microsoft 365. Using a paid third-party migration platform such as AvePoint or BitTitan MigrationWiz, IT Partner migrates everything the platform supports — mailboxes with email, folders, contacts, calendars, and tasks; Google Drive to OneDrive for Business; Google shared drives to SharePoint Online or Microsoft Teams; and Google Forms and Google Sites content. Choose this service when the free Microsoft-sponsored migrations are not enough: Microsoft's native migration tools do not migrate Google Tasks, Forms, or Sites. Pricing is quote-based — request a quote to get a fixed written price for your scope.
What this engagement is
IT Partner plans and performs a comprehensive cutover migration from Google Workspace to Microsoft 365 using a professional third-party migration platform (for example AvePoint or BitTitan MigrationWiz). Unlike the Microsoft-native tooling used in IT Partner's free Microsoft-sponsored migrations, third-party platforms can migrate Google Tasks, Google Forms, and Google Sites content — as well as Google Drive to OneDrive for Business and Google shared drives to SharePoint Online or Microsoft Teams — in addition to email, folders, contacts, and calendars. The definitive item-type scope depends on the selected platform and is confirmed in the written quote. The project is considered successful when all in-scope data is migrated to the Microsoft 365 tenant.
Success criteria
What you receive
How the work unfolds
Confirm project scope, mailbox count, target cutover window, communication approach, customer points of contact, required administrator access, licensing readiness, DNS responsibilities, and any high-risk users or mailboxes that need special handling.
Confirm the migration scope across mailboxes (email, folders, contacts, calendars, and tasks), Google Drive and shared drives, Google Forms, and Google Sites; select the third-party migration platform (for example AvePoint or BitTitan MigrationWiz); estimate platform license fees during discovery; and confirm the definitive scope and fixed price in the written quote.
Review the Google Workspace environment, administrator access, domain status, enabled services for mail, contacts and calendars, mailbox inventory, large mailbox risks, source connectivity, and any conditions that may affect migration throughput or completeness.
Prepare recipient objects in Microsoft 365 by creating cloud users or configuring directory synchronization where applicable, validating primary SMTP addresses and aliases, and confirming that required Exchange Online licenses are available and assigned.
Configure the third-party migration platform (for example AvePoint or BitTitan MigrationWiz), establish source and destination connections, map source mailboxes to Microsoft 365 users, begin the initial synchronization of mailbox data, contacts, calendars, and tasks, and monitor for authentication, throttling, or item-level errors.
Review migration dashboard/status reports, validate representative user mailboxes in Exchange Online, confirm folder structures and migrated item types, address migration errors where possible, and identify any users requiring remediation before cutover.
Coordinate the mail-flow cutover with the customer, including customer-performed updates to the domain MX record and any required mail-related DNS records, then verify that new inbound mail is delivered to Exchange Online and outbound mail is functioning as expected.
Run the final synchronization after DNS cutover to capture delta changes from the source system, reprocess failed or skipped items where supported by the migration tool, and confirm that newly delivered mail is landing in Microsoft 365.
Perform post-cutover validation with the customer, confirm user access from supported clients and mobile devices, verify mail send/receive, Exchange Online Protection and necessary transport rules, document any remaining exceptions, and provide the closeout report.

Limitations & technical notes
Frequently asked questions
What does the Comprehensive Google Workspace to Microsoft 365 Migration service include?
This service migrates everything the selected third-party migration platform supports: mailboxes with email, email folders, contacts, calendars, and tasks to Exchange Online; Google Drive to OneDrive for Business; Google shared drives to SharePoint Online or Microsoft Teams; and Google Forms and Google Sites content. IT Partner also plans the migration, configures the destination Microsoft 365 tenant, creates and configures users, assigns licenses, controls the data migration process, and provides a project closeout report.
Does this service migrate Google Drive files to Microsoft 365?
Yes. Google Drive data is migrated to OneDrive for Business, and Google shared drives are migrated to SharePoint Online or Microsoft Teams, as part of the comprehensive scope confirmed in the written quote.
How long does the Google Workspace to Microsoft 365 cutover migration take?
The schedule depends on the confirmed scope and data volumes and is finalized in the written quote. The plan may vary depending on customer needs, mailbox size, data volumes across Drive, Forms, and Sites, readiness, DNS access, and any issues found during verification, so the exact schedule should be confirmed during kickoff.
What prerequisites must be in place before starting the migration?
The customer must have a Microsoft 365 tenant with Exchange Online licenses, access to the email domain DNS zone, and admin access to Google Workspace.
What happens during the migration engagement?
The engagement includes a kickoff meeting, pre-migration source system health check, user creation or AD Connect configuration, migration start, migration verification, MX record change to the new Microsoft 365 tenant, final migration, and issue fixing if needed. IT Partner uses a migration utility and a controlled migration process to move mailbox data while reducing errors from manual transfer.
Will users be created in Microsoft 365 as part of the service?
Yes, creating and configuring users is included in IT Partner’s responsibilities for this migration. License assignment is also included, provided the customer has the required Microsoft 365 tenant and Exchange Online licenses available.
Is AD Connect configuration included?
The implementation plan includes either user creation or AD Connect tool configuration as a milestone. The exact approach depends on the customer environment and should be confirmed during planning.
Who is responsible for DNS changes during the cutover?
The customer is responsible for performing internal and external DNS changes as required, including changes to the email domain DNS zone. IT Partner’s implementation plan includes coordinating the MX record cutover to the new Microsoft 365 tenant, but the customer must have DNS access and support the required changes.
How is mail flow switched from Google Workspace to Microsoft 365?
Mail flow is switched by changing the MX record to point to the new Microsoft 365 tenant. After cutover and verification, one of the success criteria is that mail can be sent and received using Exchange Online.
Will there be downtime during the cutover?
No downtime window is guaranteed. The migration includes an MX record change and a final data pass, so plan for a coordinated cutover window and confirm the expected business impact with IT Partner during migration planning.
What mailbox data is included in a full mailbox migration?
The mailbox portion of the scope includes email data, email folders, contacts, calendars, and tasks from Google Workspace to Microsoft 365 / Exchange Online. If only email and email folders are required, without contacts, tasks, and calendar, IT Partner's Cutover Exchange Online Migration from any IMAP Email System service should be ordered instead; for mailbox-only migration with contacts and calendars, the free Microsoft-sponsored Cutover Google Workspace to Microsoft 365 Migration - Email, Contacts, and Calendars is available.
What is not included in this service?
Customer team training, migration of corporate documents from file servers or other non-Google sources to SharePoint Online, desktop software settings, and documentation beyond the project closeout report are not included. Some of these items may be available as additional services or for an additional fee.
Does this service configure Exchange Online Protection?
Exchange Online Protection configuration is part of the stated success criteria. The project is considered successful in this area when Exchange Online Protection is configured and working.
Are transport rules included in the migration scope?
The success criteria state that all necessary Transport rules are created and working. The exact rules required depend on the customer’s mail-flow requirements and should be addressed during the migration plan and tenant configuration.
What responsibilities does IT Partner handle during the migration?
IT Partner gathers information, verifies the original Google Workspace environment, configures the destination Microsoft 365 tenant, creates and configures users, assigns licenses, creates the migration plan, provides informational messages for users, and starts and controls the data migration process. IT Partner also provides a closeout report with final project status, acceptance criteria matching, outstanding issues if any, and final budget.
What responsibilities remain with the customer during the migration?
The customer must coordinate internal resources and staff schedules, provide a dedicated point of contact, review and approve deliverables, configure network equipment, perform DNS changes, identify high-risk users, ensure contact and calendar services are enabled for users, and provide end user support. These responsibilities are important because IT Partner depends on timely access, approvals, and customer-side changes to complete the cutover.
How should high-risk users be handled for this migration?
The customer is responsible for helping identify high-risk users, including top executives and VIP users, users with mailboxes of 50 GB or larger, and users with deleted folders of 30 GB or larger. Identifying these users early helps IT Partner plan the migration and verification process appropriately.
What does the customer receive at the end of the project?
At completion, the customer receives a project closeout report showing final project status, acceptance criteria matching, outstanding issues if any, and the final budget. The intended outcome is that users can access Exchange Online from desktop PCs, mobile phones, and tablets, and that migrated email, contacts, calendars, and tasks are accessible in the Microsoft 365 tenant.
Can this service be used for a partial migration from Google Workspace to Microsoft 365?
No — this service is positioned as a comprehensive migration covering mailboxes (email, folders, contacts, calendars, and tasks), Google Drive and shared drives, Google Forms, and Google Sites. If the customer needs only email and email folders without contacts, tasks, and calendar, IT Partner's Cutover Exchange Online Migration from any IMAP Email System service should be ordered instead; for mailbox-only migration with contacts and calendars, the free Microsoft-sponsored Cutover Google Workspace to Microsoft 365 Migration - Email, Contacts, and Calendars is available.
Why use a paid third-party migration service instead of the free Microsoft-sponsored migration?
IT Partner's free Microsoft-sponsored migrations use Microsoft's native migration tools, which do not migrate Google Tasks, Google Forms, or Google Sites. A paid third-party migration platform such as AvePoint or BitTitan MigrationWiz can migrate these additional data types, plus Google Drive and shared drives, in one coordinated project. If mailbox data — or mailbox plus Google Drive — is all you need, the free Microsoft-sponsored migrations are the better choice.
How much does the comprehensive migration cost?
Pricing is quote-based: request a quote and IT Partner will confirm a fixed written price for your scope before work begins — you pay after you approve delivery. Third-party migration platform license fees are estimated during the discovery phase and included in the quote.
Which migration tools are used for this service?
IT Partner selects a professional third-party migration platform per project — for example AvePoint or BitTitan MigrationWiz. The platform choice depends on your scope and data types, and it is confirmed together with the definitive scope and fixed price in the written quote.
