Cigati Solutions, a provider of email migration, cloud migration, backup, and data management solutions, has introduced its Microsoft 365 Tenant to Tenant Migration Tool. The software is designed to help organizations transfer Microsoft 365 data between separate tenants while maintaining folder structures and data consistency. It supports the migration of mailboxes, contacts, calendars, SharePoint sites, and OneDrive data through a centralized migration platform.
The tool is designed for organizations managing mergers and acquisitions, divestitures, tenant consolidation, organizational restructuring, and large-scale tenant migration projects. Its migration controls allow administrators to plan workload transfers, map source and destination accounts, apply filters, and monitor migration activities.
Secure Microsoft 365 Cross-Tenant Migration
The Microsoft 365 Tenant to Tenant Migration Tool enables administrators to migrate primary and shared mailboxes, contacts, calendars, SharePoint sites, and OneDrive data between Microsoft 365 tenants. The software preserves mailbox folder hierarchy and maintains the organization of supported SharePoint and OneDrive content during the migration process.
The software uses Microsoft OAuth 2.0 and Graph API authorization and supports Multi-Factor Authentication (MFA). This provides administrators with a modern authentication method for accessing Microsoft 365 environments during migration.
Flexible Source and Destination Mapping
The updated migration workflow allows administrators to map source and destination mailboxes, OneDrive accounts, and SharePoint sites before starting the migration. This helps ensure that data is transferred to the intended destination and provides greater control over large migration projects.
The tool also supports default and custom folder mapping for mailbox migration, helping administrators maintain an organized structure in the destination tenant.
Incremental and Selective Migration
For staged migration projects, the software provides a Skip Previously Migrated option. This supports incremental or delta migration by preventing previously migrated items from being transferred again during subsequent migration runs.
Administrators can also use date-based filtering to migrate mailbox data from a specific period. This allows organizations to select relevant data instead of processing an entire mailbox when a more targeted migration is required.
Duplicate Data Handling
The Microsoft 365 Tenant to Tenant Migration Tool includes deduplication options for email migration. Duplicate email items can be identified using selected properties, including sender, recipient, subject, BCC, and message content.
This capability helps administrators manage redundant mailbox data and maintain a more organized destination environment after migration.
SharePoint and OneDrive Migration
The solution supports migration of SharePoint document libraries, site collections, lists, folders, and related content, along with OneDrive files and folders.
Administrators can apply SharePoint content-type filters and select documents, lists, or both. File-extension and file-size filters are also available for SharePoint and OneDrive migrations, providing additional control over the data included in a migration project.
Microsoft 365 Mailbox Export to PST
In addition to cross-tenant migration, the software allows administrators to export Microsoft 365 mailbox data to PST format. Users can configure destination locations, naming preferences, and PST splitting options based on their mailbox data management requirements.
Real-Time Monitoring and Migration Reports
The software provides an Active Tasks dashboard for monitoring migration activities. Administrators can track migration progress, review completed and pending tasks, and identify exceptions or failures.
The centralized reporting section provides migration, export, and deduplication reports, while detailed audit logs help administrators review migration activities and validate results.
Easy, Flexible, and Scalable
The Cigati Microsoft 365 Tenant to Tenant Migration Tool is available for Windows and macOS environments. It supports batch migration and is designed for projects ranging from individual mailbox transfers to large-scale tenant consolidation.
The demo version allows migration of up to 50 emails per folder, SharePoint and OneDrive files up to 20 MB, and up to 25 contacts and 25 calendar events per mailbox, allowing users to evaluate the software before purchasing the full version.
