Microsoft 365 Tenant to Tenant Migration

Tenant-to-tenant migration is the process of moving users, mailboxes, files, Teams data, and other Microsoft 365 content from one Microsoft 365 tenant to another. This is typically required during mergers, acquisitions, divestitures, or tenant consolidation projects.

Cloudiway migrates Exchange Online mailboxes (emails, calendars, contacts, tasks), OneDrive files, SharePoint sites and document libraries, Microsoft Teams (channels, conversations, files), distribution lists, security groups, and Intune configurations. All permissions and sharing settings are preserved.

Migration duration depends on data volume and number of users. Cloudiway uses parallel processing to maximize throughput. A typical 50GB mailbox migrates in 4-8 hours. Large enterprises with thousands of users can complete migrations in weeks rather than months with proper planning.

Yes. Cloudiway uses delta synchronization technology that allows users to continue working in the source tenant throughout the migration. Multiple sync passes capture all changes, and the final cutover is seamless with zero downtime.

Cloudiway automatically maps users and groups between tenants and recreates permissions in the destination. Shared mailbox access, OneDrive sharing, SharePoint permissions, and Teams membership are all preserved based on configurable mapping rules.

Cloudiway provides enterprise coexistence tools including calendar free/busy lookup between tenants, GALSync for global address list synchronization, and mail routing to ensure seamless collaboration during the transition period.

Yes. Cloudiway uses OAuth 2.0 authentication, encrypts all data in transit, and complies with GDPR, SOC 2, and HIPAA. No data is stored on Cloudiway servers. Litigation hold and compliance data are preserved during migration.

Yes. Cloudiway supports migrations involving GCC, GCC High, German cloud tenants, and GoDaddy-managed tenants. Custom configurations are available for specialized compliance requirements.

Pricing is based on the number of users and data types being migrated. Cloudiway offers flexible per-user licensing with volume discounts. Contact sales for a custom quote based on your specific migration scope.

Yes. Cloudiway offers professional services including migration assessment, planning, pilot execution, and 24x5 support during production migrations. Our experts have completed thousands of successful tenant migrations.

Yes. Office 365 was rebranded to Microsoft 365 in 2020, but the platform and migration process are identical. Whether your tenant still uses Office 365 licensing or has been upgraded to Microsoft 365, Cloudiway handles the migration seamlessly.

The source tenant remains intact during and after migration — Cloudiway copies data, it does not move it destructively. If a critical issue is found post-cutover, end users can be redirected back to the source tenant by reverting MX records and OneDrive redirections, while a remediation plan is executed. Most projects keep the source tenant active for 30 to 90 days as insurance.
