Microsoft 365 tenant-to-tenant migration
Need to merge organizations, split units, or transfer users and data between Microsoft 365 tenants? We handle the entire migration process so your team can stay productive without interruptions.
Move your Microsoft 365 environment without hassle
We manage complete migrations between tenants, including Exchange Online, OneDrive, SharePoint, and Teams. No data loss, minimizing impact for your users.
Email migration
We transfer all mailboxes without losing messages, rules, or settings.
OneDrive, SharePoint, and Teams
We migrate files, sites, and teams maintaining permissions and structure.
Consolidation or separation
We unify or divide users and domains according to your organizational needs.
Phased planning
We define each stage of the process to minimize risks and interruptions.
Pilot testing
We validate data and behavior before executing the final migration.

Technology and experience
Microsoft's native tools do not easily support tenant-to-tenant migrations. In mergers, acquisitions, or restructurings, moving emails, files, permissions, and users can become a complex technical challenge. That's why we offer a professional, secure service designed to minimize impact on your operations.
Tenant-to-tenant migrations require precision, control, and reliable tools. We use Microsoft-certified solutions and proven methodologies to ensure a process without data loss, with prior validations and carefully planned execution. We take care of everything: from initial analysis to final configuration, so the transition is smooth and without surprises.

How we work
Every migration follows a phased process so there are no surprises:
1. Assessment
We audit the source and target tenants: users, mailboxes, groups, SharePoint sites, Teams, domains and licenses.
2. Planning
We design the migration plan, the phased schedule and the communication with your users, at the times that least affect your business.
3. Pilot
We migrate a small group of users and validate data, permissions and behaviour before continuing.
4. Migration
We move email, OneDrive, SharePoint and Teams with Microsoft-certified tools, with pre-syncs so the final cutover is fast.
5. Cutover and support
We move the domains, update DNS and support your users through their first days in the new tenant.
