It is also possible to move a tenant from one to the other via native ways. However, this may only be on a small scale. These organizations work on a larger scale and manage multiple users and employees working under them. To handle all this efficiently, operations need advanced identity mapping, data separation, and collaborative data that are not natively supported.
Consequently, administrators have to resort to various approaches, with each one being complicated and requiring their own sets of preparations. Additionally, they have to keep the scripts in good condition to ensure they don’t have any faults during bulk migration. Using an Office 365 tenant migration tool avoids having to go through all of this.
An ideal migration tool should consist of these features. The points below address those features that determine if a tool is a suitable choice in practice.
There are several migration tools to successfully migrate a tenant from a source location to a destination location. In this section, we will look at some of the top Office 365 tenant migration tools available.
The Aryson Tenant-to-Tenant Migration Tool is a PowerShell script-free, Graph API-based tool used by enterprise administrators. This tool migrates email, attachments, calendars, contacts, and licensed shared mailboxes of the Exchange Online mailbox. It also migrates files and folders along with metadata from OneDrive, SharePoint Document Libraries & Sites, channels, and messages from Teams. Copying existing Teams as new Teams and copying existing channels into existing Teams is also possible.
Best for: Enterprises and IT administrators who need mailboxes, OneDrive, SharePoint, and Teams in one tool during mergers, consolidations, or restructuring.
Follow the points below to migrate your source tenant to the destination tenant without any issues.
Note: In both of the above sections, we learned about features and limitations of this tool. However, it has more to offer. Users can go through our software guide to know more about the capabilities and uses of this tool.
Most of the time, administrators’ first choice is Microsoft’s own tool, Migration Orchestrator. It’s always best to get an overview of Microsoft Orchestrator and know how it works properly to avoid any issues. In this way, it eliminates any need to depend on any other dedicated migration tool. With the help of this native tool, users can migrate mailboxes, OneDrive accounts, and Teams chats and meetings in batches.
As one of the oldest migration platforms for cloud service providers, Migration Wiz is used by numerous cloud providers. It supports Microsoft 365, Google Workspace, Exchange, IMAP, and many other items.
Quest On-Demand Migration is usually assessed by bigger companies with complicated tenant-to-tenant migration needs. It offers formal discovery, coexistence, and migration management with enterprise-level management capabilities. Quest On Demand has been developed by Quest Software. This is used by IT teams only when data is in large quantities.

There are many Microsoft 365 migration tools, but selecting the best one among them relies on admins’ needs. Both native and professional tools are suitable choices. But one particular tool might not meet all of the needs. This is because each tool is associated with certain limitations that need to be known before choosing them. However, for a large organization with extensive needs, dedicated tools are best. Therefore, it is recommended to use the Aryson tenant-to-tenant migration tool. In such scenarios where an organization requires proper mapping along with a monitoring process, they can opt for this tool.
Ans. Yes. Most dedicated tools migrate emails, attachments, contacts, and calendar items along with the folder structure. Microsoft’s native mailbox migration moves user-visible content, email, contacts, calendar items, tasks, and notes. Aryson’s tenant-to-tenant migration tool also migrates licensed shared mailboxes and lets administrators include, exclude, or customize attachment transfer.
Ans. First, it’s important to identify the needs. Start by assessing the situation, then assess workload coverage, map users, incremental support, monitoring, and cost. Match the project size as well as the team’s experience level. Also, always include preparation and verification time when checking the price of the tool.
Ans. The Aryson Tenant-to-Tenant Migration Tool supports incremental runs through its Skip Previously Migrated Data option. This transfers only new or missing items on repeated migrations.
Ans. A dedicated migration tool provides dashboards, activity logs, and reports. In the Aryson tenant-to-tenant migration tool, a centralized dashboard shows progress and migration reports that help administrators to verify results. Reviewing these outputs after every pilot and batch eliminates problems.
Ans. The Aryson Tenant-to-Tenant Migration provides bulk processing and an interface designed for administrators to handle mixed workloads. The best choice depends on migration size, workload type, and the amount of configuration done.
