Transfer Microsoft Tenant, Teams, or SharePoint to Another Tenant or Save Data Locally-All In One Place!
Relocate all items within a mailbox to another mailbox without missing any metadata or folder structure. This includes moving all emails, including drafts, attachments, sent items, and deleted items from primary and shared mailboxes.
When transferring calendar items (e.g., events, recurring meetings, appointments, etc.) or contacts from the professional mailboxes, alongwith all key details, all participants and sharing options will be maintained on the new tenant with 100% preservation.
The full migration of SharePoint document libraries/lists/pages/site collections, and related data, while maintaining the associated users, will be performed via Graph API, maintaining mapping and site architecture throughout the cross-tenant migration.
OneDrive content (file metadata, sharing permissions, folder structure, versioned docs) can be moved from tenant to tenant without causing any interruptions or data loss for user storage ecosystems in a unified interface for all users.
Secure all your public/private Teams channels, chats, files, tabs, messages, apps, and Planner when migrating between tenants with one-to-one user mapping using Migration API and incremental syncs so that nothing remains behind.
Popular scenarios where this dedicated Microsoft Office Tenant to Tenant Migration Proves Useful.
Combine the data from a separate Office 365 tenant you're acquiring into your tenant to access mailboxes, SharePoint sites,Teams and Planner, and OneDrive accounts altogether. Consolidate data in a centralized environment and retain access permissions and user identity mappings. Best to simplify the administrative control and governance management for multiple tenants.
If you are splitting one tenant into three or more or consolidating numerous tenants into one (global), this tool allows you to conduct a selective migration to maintain structure and continuity. Make sure no disruption occurs with active users and assign tiered licences according to the organization's and departments' requirements, configurations, and rights.
If you have multiple departments/tenants with thousands of mailboxes merging into one global location, the need for deduplication of files becomes greatly increased. Requires migration throughput with a load-balancing mechanism and appropriate mailbox mapping with each user. Prepares detailed migration logs and output summary reports for audit and compliance.
Explore how this Tenant Migration Tool simplifies large-scale business-critical migrations.
Reliable Multi-Tenant Migration
Migrate data between multiple Microsoft 365 tenants securely with the specialized software. It helps helps restructure domains and merge tenants securely and accurately with zero data loss. You can migrate and copy Mailboxes, SharePoint sites, Team channels, chats, Planner, and OneDrive data with proper mapping and de-duplication.
Source and Destination Mapping
SysInfo Microsoft 365 Migration Tool allows mapping the source and destination tenant accounts, multiple teams, OneDrive, and SharePoint sites to ensure that each piece of data moves to the correct mailbox. It helps eliminate redundancy, manage storage, and access emails easily with custom saving or mapping to native folders with full ownership.
OneDrive to SharePoint Migration
Utilize user-to-site mapping to transfer the OneDrive files straight into the SharePoint site. Specify the drive by display name, UPN, licence, storage, and status & site by Name, URL, or Site ID, and opt for either the default Document Library to receive the files or any other custom folder. Use filters similar to those of other components in the software, which means that files will remain unique.
SharePoint to OneDrive Migration
Rewind the migration movement and send SharePoint document lists and libraries back to OneDrive of the user, directing them to the main OneDrive folder or choosing another storage folder. Note that the files that are already present in the same destination will remain intact and counted as skipped in both migrations. Map the drives and sites accordingly as desired and perform secure migrations
Incremental Migration of Mailboxes
The Skip Previously Migrated feature in all three sources allows you to ensure that no data is moved twice. It ensures that only the unique data is migrated and skips it with Microsoft’s Graph API to avoid overwriting or duplication of the mailboxes.
Selective Migration with Date Range
Transfer all emails according to a limited timeframe. Set Start and End dates. This is particularly important for phased migrations, organizations with legal holds, and organizations that don’t want to migrate years of "noise" (irrelevant emails).
De-Duplicating Similar Mailbox Data
Before or during the migration of emails, the SysInfo Microsoft 365 Migration Tool allows you to flag (and remove) duplicate emails based on the data in the following fields: From, To, Subject, BCC, and Body of the email. This allows for a clean mailbox at the end of each migration.
Export Microsoft Mailboxes to PST
No requirement for an additional tenant? You can export Microsoft 365 mailboxes directly to a PST. You can choose destination folders, apply custom naming, splitting the PST doing so by either size and manage attachments selectively for archive/litigation purposes.
Modern OAuth 2.0 Authentication
Use Microsoft’s authentication portal directly for login. There are no passwords saved in the tool. Full compatibility for MFA. The admin consent for permissions for the software is managed entirely via Graph API and will not require any alternative methods.
Intelligent Attachment Handling
Office 365 Tenant to Tenant Migration Tool allows smart attachment handling during the email migration process. You can choose to migrate emails with attachments or exclude attachments to reduce mailbox size with specific controls for optimized storage and quick migrations.
File Size Filter for Custom Migration
When migrating OneDrive and SharePoint, you get a file size filter to set minimum and maximum file size limits before starting the migration. This means you can skip very large files or smaller ones as required. It helps optimize speed and reduce bandwidth during the migration.
Filter Data by File Extensions
SysInfo Microsoft 365 Tenant to Tenant Migration Tool has a file extension-based filtration option in SharePoint and OneDrive. It allows you to include or exclude specific file types by extensions, such as .pdf, .docx, .xlsx, or .jpg. This reduces the migration time and transfers only relevant data.
Refine with Content Type Filtering
The Content Type Filter (Only Documents or Only Lists) is available only with SharePoint Migration within the SysInfo Microsoft Tenant to Tenant Migration Tool. It allows admins to manage the migration of only documents, only lists, or both as required, avoiding unnecessary transfers for scalable site management.
Mapped Default Mailbox Folders
Migrate into Mapped Default Folder is only a feature available with Mailbox Migration. It moves emails from one tenant to another tenant account in the same default folder, like Inbox, Sent, Drafts, and Deleted (Trash). This way, everything gets stored in its right place without any mix-ups, and the mailbox looks familiar after the migration.
Live Migration Progress Tracking
Track your active migration tasks and verify the progress of each of the folders during migration with real-time evaluation. View full migration reports when successful. You can identify where you have had failures or exceptions with your migration, so you don’t have to complete the entire migration task again to fix any issues.
System Compatibility and Demo
The reliable software functions extremely well on the latest and previous versions of Windows and Mac OS. It allows you to run a pilot test to evaluate the functionalities and freely migrate upto 50 emails per folder. Files larger than 20 MB are skipped both in OneDrive, Teams, and SharePoint, and only 5 lists are transferred for free.
Admins can now unify Microsoft Teams migration with confidence across tenants. Select specific Teams or individual channels with full control for what exactly gets transferred. Preserve your Teams structure and its components during migration with full convenience.
Transfer data from all teams and their respective public/private channels either as a new team or an existing channel, preserving ownership and permissions.
Move your channel messages (including those marked important), files, connected apps, and tabs via Microsoft Graph Migration API for continuous working without rebuilding.
Migrate plans, buckets, tasks, assignments, due dates, checklists, references, and tabs for each time to track projects intact along with team communications with no loss.
Conversations, announcements, replies, quotes, reactions, GIFs, meeting links, recorded videos, loop components, and mentions (@) are moved securely, preserving channel hierarchy & collaboration structure with the option for name configuration at the destination.
Map the source and destination Team user accounts via drag and drop functionality or bulk CSV import instead of auto-provisioning, finalizing ownership, user permissions, and membership stays for the right person in the target migrated Teams without any intended risks.
Use Skip Previously Migrated Items to continue the Teams migration from the last checkpoint and only select newly added or updated items. Track user activities, migration, status, and progress in real-time by log files, for official documentation purposes.
No migration tool works without boundaries, and knowing them beforehand helps you plan and prevent risks in the near future. This tool is built to handle the most common and complex migration needs with precision. With it, as every other migration solution that works along with Microsoft platform boundaries, certain constraints apply here too. Here’s what you must know before diving deep into the migration with this specialized tenant to tenant migration software.
Plan your inventory right before getting started with the bulk migration!
Note: As the platform evolves, the Microsoft 365 Tenant-to-Tenant Migrator will continue to expand, with new features, enhancements, and applicable limitations introduced over time.
Skip redundancy and optimize your storage before Tenant migrations with M365 Migrator

Secure Microsoft 365 Data Resilience for Enterprises
Perform consistent migration across Office 365, SharePoint, Microsoft Teams, and OneDrive with automated scheduling, immutable storage, and policy-driven backup. From the granular, point-in-time migration to the end-to-end encryption and role-based access control, the SysInfo Microsoft 365 Tenant to Tenant Migration Tool complies with tight industry regulations. It is designed to scale and remain highly available while protecting your mission-critical data with full integrity and reliability.
Graph API Integrated Migration
M365 offers basic migration, but it’s insufficient for large businesses and enterprises. Within the Shared Responsibility Model, Microsoft can ensure that the platform is secure, but migration is still upto the user. Therefore, using the native tools can result in permanent irrecoverability of emails, files, and SharePoint sites' content lost due to expired recycle bins, inactive accounts, accidental deletions, or overwritten data.
SysInfo Microsoft Tenant to Tenant Migration Tool uses Graph API (official interface for Microsoft services access). This provides granular, secure, reliable, and scalable tenant backup and migration. It enables direct access to tenant mailboxes, SharePoint sites, libraries, OneDrive accounts, and Teams channels via Migration API, supporting delta migrations with preserved metadata and structural consistency, something that native tools cannot offer. This helps gain complete control, eliminate permanent loss risks, and strengthen legal compliance and data retention strategies.
Common Troubleshoots and Fixes
Admin Sign-In Blocked?
Move to Azure AD → Users → [Admin Profile] → Sign-in status → Set Enabled. It is not an issue with the software but a Microsoft setting
Non-existent Site/Destination Mailbox?
Create sites and destinations in the Microsoft 365 Admin Center beforehand, as the tool doesn’t support their creation.
Wrong SharePoint permissions post-migration?
In SharePoint Admin Center, conduct permission audits. The permissions will be copied as-is; some very complicated nested structures will need to be reviewed manually.
Access Denied During Teams Access?
Open Microsoft Entra Admin Center → Applications → App Registration → Profile → Manage → API Permissions → Add → Microsoft Graph → Application Permissions and select Group, Directory, Teams, Channels read/write tasks. Tap Add and Grant Admin Consent for your Tenant.
Migration Entirely Failed? Need Rollback?
No source data is lost; everything is completely intact. Verify the CSV migration report to see what part of your migration failed. Fix the problem and re-run the migration. Review any partially migrated data in the destination before migrating again.

Check the doubts our clients have related to this software and how we have resolved them.
Ans: No. The Tenant to Tenant Migration software won’t proceed until your user account has licences assigned. When you authenticate the source account, it displays the details of the accounts with assigned and non-assigned licences. User mailboxes with licences assigned will only be able to secure their Mailbox data in PST or another tenant and Teams, SharePoint and OneDrive to other accounts.
Ans: SysInfo doesn’t create users or assign licences. This task must already be performed beforehand in the target tenant so that the software directly maps them when migrating Microsoft 365 accounts. Ensure that the destination mailboxes are provisioned and licenced before you begin copying the mailbox data.
Ans: For cross-tenant mailbox migrations, you must have Global Admin-level access in both source and destination Tenants. This is a requirement of the Microsoft platform, and not an issue with the tool. Exchange Online only uses admin-level authenticated user accounts to call the mailbox migration Graph API. To make this happen, the tool uses admin consent when performing an OAuth login to request the necessary Graph API permissions in a single transaction.
Ans: Yes, they will. The Inbox, sent items, drafts, deleted items, all custom sub-folders, lists, drives, chats, channels, and planner data will remain as they were in the source Tenant when they arrive in the destination Tenant. You will see the entire folder structure before transfer in the pre-migration preview to ensure the integrity.
Ans: Migration time depends on the mailbox volume, the total count, the number of items per folder, and the Microsoft Graph API throttling limit. Typically, a 38 GB archive transfer completes in under 2 hours.
Ans: Yes. Microsoft 365 Tenant to Tenant Migration Tool allows incremental migration logic with the Skip Previously Migrated filter. This helps avoid deduplicating data, saving time as well as storage and bandwidth for optimized migration of all tenant mailboxes, SharePoint sites, Microsoft Teams, and OneDrive files and folders.
Ans: Yes, you can perform the filtration in all mailboxes, SharePoint, and OneDrive based on date range, file size, file extension, and content types (only SharePoint and Teams). It will ensure that only the required data is moved without shadow duplication and all unnecessary items are skipped.
Ans: Yes. Copy Teams allows for the migration of all private and public channels and their files, messages, apps, and tabs using the Microsoft Graph Migration API with the 1→1 user mapping from one tenant to another.
Ans: All migrations are API-based, encrypted, and follow secure authentication protocols via Graph API and modern OAuth 2.0, ensuring that sensitive business data is protected during transfer. Moreover, nothing passes through SysInfo servers, so your data and credentials remain yours, highly secured.
Ans: Yes, you can monitor migration progress through the Active Tasks and migration logs dashboard. It allows real-time verification of the migration progress and error identification. You can even check whether data has been completely transferred, skipped, failed, etc.
Ans: Yes, SysInfo knows that most migrations don’t complete overnight and therefore, the incremental migration (Skip Previously Migrated) support by the software allows you to resume your migrations and keep working in the background even if the original tenant-to-tenant migration is in progress. It continuously monitors your source tenant to bring over the changes in the target tenant made since the last migration.
Ans: Yes. SysInfo Microsoft 365 Migration Tool supports cross-domain and tenant to tenant migrations, consolidating multiple accounts across multiple domains or to new tenants. It easily handles high-volume mailboxes, SharePoint sites, team channels, and OneDrive accounts with centralized administrative control for managing users and monitoring tasks reliably.
Ans: Yes, if the tenants you own, acquire, or divest are part of the same organization. The licence covers all subsidiaries and affiliates under the same corporate ownership. However, if you are trying to use one licence across unrelated client tenants, then it won’t suffice, as each client project must have its own licence.
Ans: Yes. The migration of Planner is possible with Team channels and chats migration. You can select to include it from the Teams Copy Options filtering panel before starting the migration.
Ans: The following Microsoft Entra ID application permissions must be granted before proceeding:
