Enterprise tenant migrations in Microsoft 365 are never simple. From data accuracy to business continuity, every detail matters. We recently had the challenge of merging two business units, requiring a full Office 365 cross-tenant migration. After comparing several vendors, we chose MailsDaddy Cross-Tenant Migration Service, and it turned out to be the right decision.
What stood out immediately was the simplicity and security of the platform. No desktop installations, no PowerShell commands—just a clean, cloud-based dashboard. It supports mailbox, archive, calendar, and OneDrive migrations with mapping done via CSV, which is a time-saver for large projects.
We started with a pilot run and completed the full migration in phases, using delta sync to ensure new or modified items were captured. Their real-time migration tracker helped keep everything organized, and their support team was available throughout—even during weekends.
Another highlight was the ability to migrate selectively, applying date and folder filters. This helped us skip outdated or unnecessary data and speed up the project timeline.
If you need a powerful, secure, and scalable solution for Office 365 tenant migration, MailsDaddy should be on your shortlist.
