Microsoft 365 Tenant to Tenant Migration Made Simple with Cigati
Summary:Organizations today often have situations where they need to move a Microsoft 365 setup from one tenant to another. This could be because of mergers buying companies, rebranding or just changing how the company is set up. This process is called tenant to tenant migration. It involves the transfer of mailboxes, OneDrive files, SharePoint content, Teams data, & user identities from the old tenant to the new one.
M365 is a platform. M365 does not have one single built‑in tool that handles a full tenant‑to‑tenant migration on its own. In practice, IT admins have to use a mix of built‑in tools and manual setups to get everything right. I have seen many teams use this approach and find it necessary. This is where a special migration tool comes in handy, and that is where the Cigati Microsoft 365 Tenant to Tenant Migration Tool stands out. It is made to handle the process in a safe & secure way.
What Is Microsoft 365 Tenant to Tenant Migration?
A tenant to tenant migration is the process of moving Microsoft 365 data and user identities from one company’s tenant to another. This is often needed when:
| Company mergers and acquisitions happen | Businesses split into new parts | New domains are. Companies change their names | Moving to a Microsoft 365 subscription | Combining many tenants into one |
Each of these situations needs careful thinking because the move must protect mailbox data, folder structures, permissions, and the way users see things during the move.
