Frequently Asked Questions

What is included in a tenant-to-tenant migration?

Our migrations include user accounts, mailboxes, OneDrive content, SharePoint sites, Teams, Groups, Planner, and other Microsoft 365 workloads. We also handle identity federation, DNS changes, and license transfers.

How do you minimize user disruption during migration?

We use incremental sync to pre-stage content before cutover. The actual cutover typically requires only a few hours of downtime, scheduled during off-hours. Users receive detailed communications and training.

Can you migrate between different Microsoft 365 regions?

Yes, we migrate between any Microsoft 365 regions including cross-geographic migrations. Data residency requirements are carefully considered and documented.

How long does a tenant-to-tenant migration take?

Timeline depends on data volume and complexity. Small organizations (under 500 users) typically migrate in 4-8 weeks. Large enterprises may require 3-6 months for planning, migration, and validation.
