Microsoft Office 365 Tenant to Tenant Migration | Forum

Over the last few years, Office 365 has become the go-to productivity platform for businesses of all sizes. As organizations continue to embrace Office 365, the need for tenant-to-tenant migrations has increased. Although Office 365 provides several built-in tools for migrating users and data, the process can still be complex and time-consuming.

Office 365 Tenant to Tenant Migration is a common requirement during mergers and acquisitions. Since many organizations rely on Office 365 when they join their data needs to be transferred to a common tenant. CodeTwo Office 365 Migration addresses the needs of such companies, making the mailbox data migration between multiple tenants far simpler compared to the native approach.

A tenant in Microsoft 365 is the domain account attached to the Microsoft 365 Suite. A tenant administrator can use all the features given in the subscription. In business-merger scenarios, the mailboxes need to be moved to another tenant. The migration is not a linear process; you need to do some preparation, meet some prerequisites, and own licenses.

Company mergers and acquisitions involve numerous challenges. Manual migrations, missing emails and documents, or unplanned email server downtime are the last thing a company needs. Office 365 Migration offers several conveniences and features that ensure the successful completion of data transfer which are not available when using the native Microsoft 365 mechanisms:

  • Automatic creation of target mailboxes and source-to-target mailbox matching.
  • Fully customizable migration scope. Select the scope of source mailboxes that need to be migrated. Use the time and folder filters available in the program to further narrow down the migrated data.
  • Automatic connection to source and target Microsoft 365 tenants. The connection is authenticated by OAuth 2.0 – the program has no access to your credentials. It also does not store the migrated data on your local disk.
  • No need for scripts – configure the entire migration process in the program via a GUI-based interface.
  • No Azure Key Vault or additional Microsoft 365 services are required.
  • Easy roll-back to the source environment. The data is copied, not moved, between source and target environments, which means the source Microsoft 365 tenant remains intact both during the migration and after you complete it.
