FreeViewer Office 365 Tenant Migration Tool

The FreeViewer Office 365 Tenant Migration Tool is a high-utility enterprise solution designed to manage the complexities of moving data between separate Microsoft 365 environments. Whether your organization is navigating a merger, acquisition, or a simple domain rebranding, this tool provides a structured, automated framework to ensure that every email, document, and calendar event is transitioned without loss or corruption.

Strategic Core Features

• Comprehensive Workload Support: Beyond basic email, the tool migrates OneDrive for Business files, Contacts, Calendars, and Tasks, ensuring a complete transition of the user’s digital workspace.

• Intelligent Delta Migration: This feature allows for incremental passes. After the initial bulk transfer, the tool identifies and migrates only new or modified items that arrived during the transition period, preventing data duplication and ensuring "Day 1" readiness.

• Advanced Data Filtering: Administrators can apply Date-Range Filters to migrate only specific timeframes of data (e.g., the last two years), significantly reducing migration time and clearing out legacy clutter.

• Precise User Mapping: To bridge the gap between source and destination, the tool offers two methods: Fetch Users (automatic discovery) or CSV Mapping (for bulk linking thousands of accounts with custom destination addresses).

• Account Priority Management: Prioritize critical accounts—such as executive or IT support mailboxes—to ensure they are migrated and operational before the rest of the organization.
