Cigati Launches Microsoft 365 Tenant to Tenant Migration Tool, Giving IT Teams a Single Platform for Secure Mailbox, OneDrive, and SharePoint Migration

Cigati Solutions, a provider of enterprise data migration and recovery software, today announced the launch of its Microsoft 365 Tenant to Tenant Migration Tool. The solution gives IT administrators a single platform to migrate mailboxes, OneDrive accounts, and SharePoint sites across Microsoft 365 tenants without relying on multiple scripts or third-party utilities.

Organizations undergoing mergers, acquisitions, or tenant consolidation often face restrictions when using native Microsoft tools, including a 50 GB per-mailbox limitation that slows large-scale projects. Cigati’s new tool removes this constraint, allowing administrators to migrate primary and shared mailboxes of any size while preserving folder hierarchy and metadata.

The tool also introduces prior and inbuilt deduplication, helping teams identify and remove redundant emails based on sender, recipient, subject, and message content before or during migration. Combined with date range filtering, administrators can target specific time periods instead of transferring entire mailboxes, reducing processing time for phased rollouts.

A key addition is incremental sync through the Skip Previously Migrated option, which allows teams to run subsequent migration passes without duplicating already transferred data. This supports staged cross-tenant migration projects where new or updated content needs to move without reprocessing the full mailbox.

“IT teams managing tenant consolidations need a tool that handles scale without losing accuracy,” said a Cigati Solutions spokesperson. “Our Microsoft 365 Tenant to Tenant Migration Tool was built to overcome native platform limitations while giving administrators complete control over mapping, filtering, and reporting throughout the process.”
