Microsoft Tenant-to-Tenant Migration Orchestrator

Microsoft has launched a tenant-to-tenant migration orchestrator solution in public preview to migrate mailboxes, OneDrive accounts, and Teams chat between tenants. ISVs have been active in the T2T space for a long time. They probably won’t welcome the new Microsoft offering, but at least the migration orchestrator legitimizes the concept of tenant-to-tenant migration.
