GoDaddy Microsoft 365 to Microsoft 365 Migration — Tenant-to-Tenant Email Cutover

IT Partner’s GoDaddy Microsoft 365 to Microsoft 365 Tenant-to-Tenant Cutover Email Migration is a professional service for moving email from a GoDaddy Microsoft 365 tenant to a Microsoft 365 tenant. It uses a cutover approach with pre-staging, so older email data is migrated before the final switch to reduce the final cutover window.

This service is for organizations moving from GoDaddy Microsoft 365 to a native Microsoft 365 tenant under their own direct Microsoft agreement. It is also suitable for companies involved in mergers, acquisitions, rebranding, geographic moves, compliance-driven tenant changes, feature-driven tenant changes, or teams that want expert help with tenant-to-tenant email migration.

There are two ways out from under GoDaddy. This service — a full tenant-to-tenant migration — moves your email to a brand-new native Microsoft 365 tenant: you get a clean tenant with the technical name and region of your choice and no GoDaddy history, at the cost of a real migration project — per-mailbox data moves, an MX cutover window, and Outlook profiles recreated on workstations. The alternative is our GoDaddy Microsoft 365 Defederation & Tenant Takeover service: we detach your existing tenant from GoDaddy so you keep it under direct Microsoft control — nothing migrates, mailboxes, OneDrive, and Teams stay exactly where they are, and there is no MX downtime, which makes it faster and cheaper. The trade-offs: you keep the tenant exactly as GoDaddy provisioned it, including the permanent .onmicrosoft.com technical tenant name, and any GoDaddy-era configuration stays for you to clean up. As a rule of thumb, defederate if you are happy with the tenant itself and just want GoDaddy out of the picture; migrate if you want a fresh start, a different tenant name or region, or you are consolidating tenants anyway.

The service includes pre-stage migration of older emails and folders, final cutover of recent emails, calendars, contacts, and rules, and user, contact, and group migration using Microsoft Entra Connect or CSV. It also includes domain management with DNS and MX record updates, post-migration verification and health checks, project management, a closeout report, and post-migration support.

The listed service duration is 3 weeks. The project uses staged preparation and migration tasks, including kickoff, source tenant health check, resource export, user provisioning, pre-stage migration, domain preparation, final cutover, verification, and project closeout.

The service is priced at $35 per mailbox plus a $3,500 tenant fee, quoted in writing before work begins — you pay after you approve delivery. The tenant fee covers planning, tenant preparation, pre-stage setup, and cutover coordination; the per-mailbox fee covers each migrated mailbox.

IT Partner requires Global Admin access to both the GoDaddy Microsoft 365 source tenant and the destination Microsoft 365 tenant. DNS zone access is also required, because the migration includes domain preparation and DNS/MX record changes during cutover.

The client is responsible for providing Global Admin access to both tenants and DNS zone access. These are required because IT Partner must export source resources, provision destination users, prepare the domain, switch MX records, and complete verification tasks.

Some email downtime is expected during the domain MX switch, because Microsoft does not allow the same domain to exist in two tenants at the same time. IT Partner reduces the business impact by pre-staging older email data before final cutover, which helps minimize the final cutover window.

No. Exchange Online Protection configuration is not part of the migration scope — the destination tenant keeps its existing protection settings, and moving mailboxes does not change how mail is filtered. If you need EOP reviewed or configured in the destination tenant, that is scoped as separate work.

Post-migration support should cover migration-related stabilization after cutover. Typical covered items may include mail-flow validation, mailbox access issues, missing-item investigation, calendar/contact/rule validation, and DNS or EOP follow-up. Exact support duration, support hours, escalation process, any SLA coverage, extended hypercare, after-hours support, user training, endpoint repair, and unrelated Microsoft 365 administration should be confirmed or separately scoped.

The standard email migration scope does not include migration of OneDrive, SharePoint, Teams content, Teams chats, Planner, Power Platform assets, public folders, third-party archives, or PST ingestion unless separately scoped. It also does not include endpoint reconfiguration, Outlook profile rebuilds, mobile setup, source tenant decommissioning, GoDaddy subscription cancellation, identity redesign, Microsoft Entra Connect remediation, SSO/MFA projects, custom SMTP relay remediation, mail-flow connector redesign, DKIM/DMARC/SPF policy redesign beyond basic DNS cutover, after-hours/weekend cutover, or extended hypercare unless agreed in the statement of work.
