Download the Aryson Microsoft 365 Migration Tool and securely connect your source and destination tenants using modern authentication. Then, it lists all mailboxes, SharePoint sites, and OneDrive accounts, providing full visibility of data for migration.
Use advanced filters to move only the data you need. Apply date ranges, select specific file or item types, exclude empty or deleted folders, and skip previously migrated items. These options ensure precise, migration for both small and large-scale environments.
Now, you can monitor migration in real-time via the Active Tasks dashboard and review detailed logs in the All Reports panel. Verify mailboxes, SharePoint, and OneDrive data in the destination tenant to ensure complete data integrity.
Aryson allows organisations to migrate data between multiple Microsoft 365 tenants easily and securely. It helps businesses merge tenants, restructure domains, or move users from one tenant to another without data loss. This feature supports the migration of mailboxes, SharePoint sites, OneDrive accounts, and other Microsoft 365 data. It ensures proper user mapping, maintains folder hierarchy, and keeps permissions intact during the transfer.
Microsoft 365 Migration Tool mapped the source to the required destination for migrating your data. This mapping makes sure that each email and folder is transferred to the correct mailbox without confusion. It helps users to avoid data loss and duplication issues, ensuring a secure and accurate data migration within the ecosystem. The mapping feature is available for the mailbox, SharePoint, and OneDrive.
With the help of the Aryson Microsoft 365 Migration Tool, you can prevent the transfer of duplicate data. When you enable these features, it will detect the duplicate files or emails that have already been migrated in a previous migration. Hence, it saves your time and reduces the storage, and makes sure that only new or missing data is transferred.
Aryson's Microsoft 365 Migration Tool allows you to migrate data for a specific time period. When you select the Start Date and End Date, it can migrate only the emails or files received or sent during the chosen range. This feature is available in OneDrive, SharePoint, and Mailbox to save migration time and focus on only the important data for migration.
Custom/Parent Folder Name
The Custom Folder Name feature allows users to define a specific folder name for easy recognition in the destination. Instead of merging data into existing folders, it creates a new folder with the user-defined name, keeping migrated content separate and well organised. Helpful to maintain clarity with current mailbox data, and makes it easier for users to identify.
Embedded with File Size Filter
SharePoint and OneDrive have a File Size Filter option. It allows administrators to set minimum and maximum file size limits before starting the migration. This means you can choose to migrate only files within a specific size range while skipping very large or very small files. So, you can optimise migration speed, reduce bandwidth consumption, and ensure better control over SharePoint and OneDrive.
Remove/Duplicate Email Detection
Once you enable this feature, it automatically identifies and skips duplicate emails during the transfer process. However, it is only available in mailboxes and transfers emails based on subject, body, recipients, from sender & to recipients. This prevents multiple copies of the same email from being migrated to the destination mailbox. It helps maintain mailbox cleanliness and reduces storage usage.
File Extension Filter
Aryson Tenant to Tenant Migration SharePoint Software has a File Extension Filter. Although it is available only for SharePoint and OneDrive migrations, to include or exclude specific file types based on their extensions, such as .pdf, .docx, .xlsx, or .jpg. So, you can migrate only the required files while skipping unnecessary ones. By filtering file extensions, users can reduce migration time with data accuracy.
Advanced Content Type Filter
The Content Type Filter (Only Documents or Only Lists) in the Microsoft 365 Migration Tool is a feature available only for SharePoint migrations. It allows administrators to choose whether to migrate only document libraries, only lists, or both. Its selective option helps you to move specific SharePoint content based on your requirements. By filtering content types, users can avoid transferring unnecessary data and ensure an organised SharePoint migration process.
Destination Path to Save Resultant File
When you convert mailbox emails to PST. It allows users to choose the specific folder within the destination mailbox where the migrated emails will be stored. Instead of merging data directly into the primary inbox or existing folders, administrators can define a custom folder path to keep migrated emails separate and organised. It helps you to maintain the mailbox structure and prevents confusion.
Split Resultant Outlook PST File
There is an advanced option for PST output, which is Split resultant PST. It allows you to divide large PST files into small and manageable parts based on size or date range before or during migration. So, you can prevent issues caused by oversized PST files. Also, it improves migration performance and reduces the risk of file corruption.
Flexible Attachment Options
Aryson Microsoft 365 Migration Tool has a different option to manage attachments. As a result, you can manage how email attachments are handled during the migration process. Administrators can choose to migrate emails with attachments, exclude attachments to reduce mailbox size, or apply specific controls as required. It helps optimise storage usage, speed up migration, and ensure better control over mailbox data.
Migrate into Mapped Default Folder
The Migrate into Mapped Default Folder option is used only for mailbox migration in Microsoft 365. It moves emails into the same default folders, like Inbox, Sent Items, Drafts, and Deleted Items, in the new account. So, everything stays where it should be. It doesn’t create extra folders or mix things up. Your mailbox looks familiar after migration, and your emails stay properly arranged.
Migrate (Emails, Contacts, Calendars & Events)
You can migrate Emails, Contacts, Calendars, and Events, which is available only for mailbox migrations in Microsoft 365. This means you can move complete mailbox data, not just emails. Along with your messages, it also transfers contact lists, calendar entries, meeting schedules, and events. Everything moves together to the new mailbox. It helps users keep their important communication and scheduling data intact.
Simple UI with Trial Version
This O365 tenant-to-tenant migration software offers a simple and user-friendly interface that makes the migration process easy, even for non-technical users. All options are clearly organized, so you can complete the process step by step without confusion. It also provides a trial version. So that the user can test features, evaluate performance, and analyze the features of this software.
Compatible with Windows and Office 365
Aryson Microsoft 365 Migration Tool is fully compatible with Windows operating systems and supports various versions of Microsoft Office 365. It works smoothly on different Windows editions, ensuring stable performance during migration. This software also integrates well with Outlook and other Office applications, allowing users to manage and migrate data without facing compatibility issues.
Microsoft 365 offers basic migration capabilities, but these are often insufficient for enterprise needs. Under the Shared Responsibility Model, Microsoft ensures the platform’s infrastructure is secure, but data migration, remains the user’s responsibility. Emails, files, and SharePoint content lost due to expired recycle bins, inactive accounts, accidental deletions, or overwritten data may be permanently unrecoverable using native tools.
Aryson Microsoft 365 Backup Solution leverages Microsoft Graph API, the official interface for accessing Microsoft 365 services, to provide granular, secure, and scalable backup and migration. Graph API enables direct access to mailboxes, SharePoint libraries, and OneDrive accounts, allowing incremental backups, and detailed metadata preservation—capabilities that Microsoft’s native recovery cannot guarantee.
By using a dedicated Graph API-powered solution, organizations gain complete control over their Microsoft 365 data, eliminate the risk of permanent loss, and strengthen compliance and data retention strategies beyond Microsoft’s built-in protections.
