Move Your Data. Keep Control. 

Whether you’re consolidating archives, moving to Microsoft 365 or retiring legacy infrastructure, Intelligent Migrator provides a secure and controlled migration path. 

Pre-migration analysis

Assess source data before migration begins, identifying volumes, anomalies and potential issues early so decisions can be made before they become problems mid-project.

Direct source-to-target migration 

Move data directly from source to target without unnecessary interim storage, reducing infrastructure requirements and limiting additional copies of sensitive information. 

Full Chain of Custody 

Track and account for data throughout the migration lifecycle with detailed reporting and audit trails. 

Intelligent data handling 

Identify malformed, corrupted or unexpected data so issues can be investigated and appropriate remediation decisions made. 

Flexible migration methods 

Use the appropriate retrieval and ingestion technologies for the source and destination rather than forcing every migration through a single method. 

Enterprise scalability 

Scale migration workloads around data volumes, infrastructure, network capacity, source and target limitations and platform throttling. 

Built for Real World Enterprise Complexity

Migration performance isn’t determined by a single software component or framework. 

Real-world throughput depends on the complete migration architecture: how quickly data can be retrieved from the source, processed, transferred and ingested into the destination, alongside network capacity, infrastructure, batching, parallel processing, platform throttling and the complexity of the data itself. 

Intelligent Migrator has been engineered and refined around these conditions. 

Depending on the migration scenario, Transvault can use direct retrieval, vendor APIs and appropriate target ingestion technologies to optimise data movement while maintaining data integrity and auditability. 

Enterprise migration isn’t simply about moving data quickly. It’s about moving it accurately, securely and reliably at scale. 

Every Item Accounted For 

A migration reaching 100% doesn’t necessarily mean every item arrived correctly. 

Legacy archive data can contain issues accumulated over years of platform upgrades, integrations and previous migrations. Malformed items, corrupted content and unexpected data can all affect the outcome. 

Intelligent Migrator is designed to surface those issues. 

Detailed auditing and reporting provide visibility into what was processed, what was successfully migrated and what requires further investigation. Exceptions can then be reviewed and appropriate remediation decisions made. 

For organisations operating in regulated or legally sensitive environments, that creates something particularly important: evidence. 

Rather than simply stating that a migration was completed, organisations can demonstrate how their data was handled from source to destination. 

A successful migration isn’t simply one that finishes. It’s one you can prove was completed correctly. 

Deep Expertise in Domino and NSF Migration

Domino has evolved through decades of versions, database structures, application features and behaviours. Migrating that data requires more than simply reading a file. 

Intelligent Migrator has been developed through extensive real-world Domino and NSF migration experience, helping organisations securely extract, interpret, transform and migrate complex Domino data into modern environments. 

Where native Domino interpretation is required, Intelligent Migrator works with HCL Notes technologies to help correctly interpret source data rather than relying entirely on an independently recreated interpretation of complex NSF structures and behaviours. 

Encrypted NSF Migration 

Intelligent Migrator supports encrypted NSF data without requiring custom development, provided the appropriate credentials are available to decrypt the source information. 

The data can then be securely processed, transformed and migrated to the target environment while maintaining the controls, visibility and auditability expected from an enterprise migration. 

The Right Migration Technology for the Right Environment 

Enterprise archives aren’t all the same and neither are migration destinations. 

That’s why Intelligent Migrator supports different retrieval, processing and ingestion methods depending on the migration scenario. 

Transvault can leverage Microsoft MAPI technologies in specific scenarios, such as where MSG processing is required. MAPI is not the standard migration transport used for Microsoft 365 migrations. 

For Microsoft 365, Intelligent Migrator uses appropriate Microsoft migration interfaces rather than relying on MAPI as the migration transport. 

This allows the migration architecture to be designed around the source, destination and data involved rather than around the limitations of a single migration method. 

We’re proud to have worked closely with Microsoft as they created the new Graph API to replace EWS for Exchange Online. I’m delighted that Transvault’s Intelligent Migrator is already successfully completing Graph based migrations in production for real customers, well in advance of the first phase of EWS retirement.

Darwin Lee Chief Executive Officer, Transvault

Microsoft Graph Ready

Microsoft’s migration technologies continue to evolve, and Transvault has been preparing for that change for years. 

Transvault has worked closely with Microsoft during the transition from Exchange Web Services (EWS) to Microsoft Graph, actively contributing insight from enterprise archive migration use cases while developing and testing Graph-based migration capabilities. 

Today, Intelligent Migrator is successfully completing Graph migrations in production environments. 

Our focus has not simply been on achieving technical compatibility. We have taken the time to validate Graph migrations against the requirements that matter in enterprise environments, including data integrity, metadata preservation, throughput, throttling, exception handling and operational performance. 

For enterprise migrations, being first isn’t the objective. Being proven is.

Whether you’re consolidating multiple archives, retiring a legacy platform or moving decades of historical email into Microsoft 365, Intelligent Migrator provides a controlled and proven migration path.

Security Isn’t Just a Feature. It’s How We Operate.

When you’re moving years or even decades of corporate communications, security cannot be treated as an optional migration feature. 

Transvault’s information security and quality management processes are independently certified to internationally recognised standards. 

ISO 27001 Certified
Information security management processes designed to protect the confidentiality, integrity and availability of information. 

Minimise unnecessary data copies
Direct source-to-target migration avoids unnecessary interim storage, reducing the proliferation of sensitive enterprise information during migration. 

Visibility throughout the process 

Detailed audit trails provide migration teams with a clear record of data processing, migration outcomes and exceptions requiring investigation. 

Security isn’t something added at the end of a Transvault migration. It’s built into how the technology and migration process operate. 

Purpose-Built Connectors for Enterprise Archives 

Intelligent Migrator supports a broad range of enterprise email archives, messaging environments and data formats developed across multiple generations of technology. 

Our supported-platform approach focuses on actual migration capabilities rather than inflating connector numbers by counting different versions, storage layers or differently branded versions of the same underlying technology as entirely separate connectors. 

Support includes leading technologies across: 

Enterprise Archives

Including Veritas Enterprise Vault, Dell/Quest Archive Manager, EMC SourceOne, Mimecast and other enterprise archive platforms.

Microsoft Environments

Intelligent Migrator FAQs

Not for standard Microsoft 365 migration transport. 

Intelligent Migrator can leverage MAPI technologies for specific scenarios, including certain MSG processing requirements, but Microsoft 365 migrations use appropriate Microsoft migration interfaces. 

Outlook components form part of the Intelligent Migrator prerequisites for certain functionality, but an additional Outlook licence is not required for the migration environment. 

Domino data can contain structures and behaviours extending beyond conventional email fields. 

Using HCL’s own technologies where native interpretation is required enables Intelligent Migrator to work with Domino data using established platform behaviour rather than relying entirely on an independently recreated interpretation of complex NSF structures. 

Yes. Intelligent Migrator can process encrypted NSF data provided the necessary credentials are available to decrypt the source information. Standard encrypted NSF migration does not require bespoke development. 

Intelligent Migrator is designed to identify problematic or malformed data so it can be investigated and appropriate remediation decisions can be made. 

This gives migration teams visibility into exceptions rather than allowing unidentified data problems to be silently transferred to the destination. 

Yes. Intelligent Migrator supports Graph migration, with migrations successfully completed in production environments. 

Transvault has spent years developing and testing its Graph capabilities while working closely with Microsoft around the transition from EWS to Graph. 

Yes. .NET Framework 4.8 remains supported as a component of supported Windows operating systems and continues to receive applicable security updates. 

The version of an underlying software framework alone does not determine migration performance or security. Migration outcomes depend on the complete application architecture, security controls, infrastructure, retrieval and ingestion methods, source and target environments and data complexity. 

Intelligent Migrator supports a broad range of enterprise archive platforms, messaging systems and data formats. 

Transvault groups related technologies and platform variants logically rather than treating different versions, storage layers or rebranded versions of the same underlying technology as completely separate connectors. 

The more important question is whether your specific source, version, data and destination are supported and whether the migration approach has been proven at enterprise scale. 

Don’t Just Move Your Data. Know It Arrived Correctly.

The success of an enterprise migration isn’t measured solely by speed. 

It’s measured by whether your data arrived accurately, securely and completely and whether you can prove it. 

With 20 years of enterprise migration experience, Intelligent Migrator gives organisations the technology, visibility and expertise required to move complex archive data with confidence.
