Tenant-to-tenant migrations that make mergers agile

The amount of time required to complete a tenant-to-tenant migration depends on the source and target as well as the scope of your migration. Throttling can be an issue with tenant-to-tenant migrations and ShareGate has mechanisms in place to avoid being throttled by Microsoft 365. Follow these practical best practices in your migration process: migrate during off hours (ShareGate will help you schedule that out!) and make sure your bandwidth is at its strongest during a tenant-to-tenant migration.

Have you considered using a third-party tool to assist in your migration? A third-party tool like ShareGate’s migration tool can help automate the migration process, save you time and manpower, and help to make sure your move is a successful one.

ShareGate makes it easy to migrate with a simple tool presented with an intuitive UI and drag and drop functionality, by centralizing your reporting to avoid hopping around various admin centers, adding flexibility not available in Microsoft’s SPMT tool, and so many more options that eliminate the need for creating time consuming PowerShell scripts and get the customized results you need.

Yes—ShareGate Pro and Enterprise are full Google Workspace‑to‑Microsoft 365 migration tools that move Gmail mailboxes and Google Calendar events with zero‑downtime cutovers.

Built for scale: Unlimited data and flat‑fee pricing mean you can move decade‑long mail archives and global room calendars without per‑GB up‑charges or throttling surprises.

Outcome: End users sign in to Outlook and see the same messages, folders, categories, and meeting series—no manual re‑invites, no regional compliance headaches.

ShareGate preserves labels, encryption, and permissions automatically so data stays classified.

• AI‑readiness: With labels preserved, Microsoft Copilot immediately respects data‑classification boundaries—eliminating the common post‑migration re‑labeling sprint and slashing time‑to‑productivity.

• Proof in the logs: Post‑migration reports show 1:1 label fidelity and flag any auto‑created labels, giving security teams audit‑ready evidence of compliance.

To ensure a seamless tenant to tenant migration, we recommend that you do the following pre-migration steps (and after that on a regular basis):

Manage clutter and archive unnecessary content in Teams
Make sure every team/group has at least one owner
Review external access and sharing links on a regular basis

A tidy environment makes it easier for users to find what they’re looking for, fast. It will also make your life a lot easier when you’re trying to decide which resources to bring with you in the migration. And, by staying on top of group ownership and external sharing links, you’re already one step ahead when it comes to ensuring data security at your destination.

Yes! We know that most migrations don’t happen in one big push overnight. You need to let your users keep working in whatever tenant they are accustomed to while you plan and migrate content in batches. Sound like an administration conundrum? Not with ShareGate.

Thanks to incremental migrations in ShareGate, you’ll be able to copy only what’s changed since your initial SharePoint migration. So if users continue to work on documents while you migrate the content around them, ShareGate continues to monitor your source tenant so you can schedule later migrations and bring over changes made since your last migration – including updates made to documents.

Tenant-to-tenant migration poses several challenges, a notable one being OneDrive tenant to tenant data migration. This can include potential data loss, maintaining the integrity of the data during transfer, and ensuring file permissions and sharing settings are correctly replicated in the new tenant. Luckily ShareGate gives you business-as-usual tenant to tenant migrations, allowing you visibility from the start of your migration process to the end, and beyond.
