All-in-One Migration Solution Supports Mailboxes, OneDrive, SharePoint, Teams, and Shared Mailboxes

Noida, India – September 21, 2026 — SysInfoTools Software, a provider of data recovery, email management, backup, and migration solutions since 2010, has announced the availability of its SysInfo Microsoft 365 Tenant to Tenant Migration Tool, designed to help organizations securely transfer Microsoft 365 data between separate tenants.

The solution is designed for businesses involved in mergers and acquisitions, domain consolidation, organizational restructuring, tenant consolidation, and other IT transformation projects. It provides a centralized approach to migrating Microsoft 365 workloads while reducing the need for complex scripting and manual migration processes.

Simplifying Microsoft 365 Tenant-to-Tenant Migration

Moving data between Microsoft 365 tenants can involve multiple workloads, account mappings, authentication requirements, permissions, and data-structure considerations. The SysInfo Microsoft 365 Tenant to Tenant Migration Tool brings these migration activities together through a user-friendly interface.

The software supports the migration of Microsoft 365 mailboxes, OneDrive data, SharePoint content, Teams data, and shared mailboxes between source and destination tenants. It is designed to help administrators manage migration projects while maintaining the organization and structure of transferred data.

Key Features of the Migration Tool

Secure Modern Authentication:

The software supports OAuth 2.0 and Modern Authentication for Microsoft 365 account access. Authentication is performed through Microsoft's authentication environment, and the solution supports Microsoft 365 environments where multi-factor authentication is enabled.

Multiple Microsoft 365 Workloads

The tool supports migration across several Microsoft 365 workloads, including:
Exchange Online mailboxes
Emails
Calendars
Contacts
OneDrive files
SharePoint sites and document libraries
Teams data
Shared mailboxes

The migration process is designed to retain relevant folder structures, metadata, timestamps, and organizational information.

Incremental Migration

The Skip Previously Migrated option allows administrators to perform subsequent migration passes without unnecessarily transferring content that has already been migrated. This can be useful for staged or phased migration projects where new data continues to arrive in the source tenant.

Duplicate Email Handling

The software provides duplicate-removal options for email migration. Administrators can identify duplicate messages using fields such as sender, recipient, subject, BCC, and message body, helping maintain a cleaner destination mailbox.

Date Range Filtering

Administrators can select a specific date range when migrating emails. Start and end dates can be configured to transfer only the required email content instead of moving an entire mailbox history.

Attachment Controls

The migration process provides options for handling email attachments. Administrators can choose whether attachments should be transferred based on the requirements of the migration project.

File Filtering for OneDrive and SharePoint

For OneDrive and SharePoint migrations, users can apply file extension and file-size filters. This allows administrators to include or exclude selected file types and define minimum or maximum file-size requirements before migration.

Migration Monitoring and Reports

The software provides an Active Tasks window for monitoring migration operations and an All Reports section for reviewing completed tasks. Administrators can identify successfully migrated items as well as failed or skipped items without having to repeat the entire migration.

PST Export

In addition to direct tenant-to-tenant migration, the software can export Microsoft 365 mailbox data to PST format. This option can be used for backup, archival, compliance, offline storage, or future restoration requirements. Users can also configure PST splitting and attachment-handling options.

Designed for Different Migration Scenarios

The SysInfo Microsoft 365 Tenant to Tenant Migration Tool is designed to support organizations managing a variety of Microsoft 365 migration projects.

Common scenarios include:

Mergers and acquisitions: Transfer user and organizational data following corporate changes.
Tenant consolidation: Combine Microsoft 365 environments into a centralized tenant.
Domain restructuring: Move data when domains or organizational identities change.
Department separation: Transfer selected business data between environments.
IT restructuring: Relocate workloads during infrastructure or organizational changes.
Managed service projects: Help MSPs manage migrations for multiple Microsoft 365 environments.
Phased migrations: Perform migration in multiple stages using incremental processing.
Administrators can map source accounts to corresponding destination accounts to help ensure that information reaches the intended Microsoft 365 accounts.
Secure Data Transfer
The migration process is designed to transfer data directly between source and destination Microsoft 365 environments using TLS-encrypted HTTPS connections. The use of Modern Authentication and OAuth 2.0 provides an authentication approach aligned with contemporary Microsoft 365 security environments.
