Data Migration Software: ArchiveMASH™ vs. TransVault
Key Takeaways
- Scale and speeds: ArchiveMASH is built on .NET 10 and supports over 62 data sources, compared to TransVault’s 29+.
- Setup dependencies: ArchiveMASH migrates data without requiring local Lotus Notes clients, Outlook/MAPI subsystems, or server Exchange Database (EDB) mounting.
- Complex data: Bluesource can modify the ArchiveMASH data migration software to update connectors and navigate complex migrations.
When planning a large-scale data or email archive migration, selecting the right software is the difference between a seamless transition and months of costly delays, broken chains of custody, or failed items.
While legacy migration solutions like TransVault have long been staples in the industry, modern enterprise environments demand higher speed, broader platform support, and tighter security compliance.
Developed in-house by Bluesource and delivered as part of our fully managed end-to-end migration service, ArchiveMASH™ sets a new standard for data migration software technology. We’ll break down how ArchiveMASH directly compares against TransVault, and why ArchiveMASH could be the superior choice of data migration software for your business needs.
| Feature | ArchiveMASH | Transvault | Benefits |
|---|---|---|---|
| .NET Framework | 10 | 4.8 | Faster execution, modern memory optimization, and security standards. |
| Can Process Malformed Domino Data | ✔ | ? Treats Malformed Data as a Failure |
Prevents migration stalls; handles corrupted legacy items smoothly. |
| Processes Domino without Notes Client | ✔ | ✘ | Simplifies environment prerequisites and eliminates legacy client dependencies. |
| Does Not Requires Outlook and Windows MAPI Subsystem | ✔ | ✘ | Bypasses MAPI bottlenecks and complex endpoint prerequisites. |
| Migrates Encrypted NSFs in O365 | ✔ | ? Requires Custom Development |
Out-of-the-box support without costly custom scripting or delays. |
| Native EDB Processing | ✔ | ? Requires Mounting in Exchange |
Exchange only supports mounting one EDB at a time, slowing down the whole migration. |
| O365 Migration Method Fully Supported by Microsoft | ✔ | ✘ | Simplifies Microsoft data migrations. |
| Supported Data Sources | 62+ | 29+ | Over double the connector versatility across legacy, cloud, and hybrid archives. |
Speed, Scale, and Modern Architecture
Built on the cutting-edge .NET Framework 10, ArchiveMASH delivers modern multi-threaded tasking and performance optimizations that leave older frameworks (like TransVault’s .NET 4.8) behind.
ArchiveMASH handles diverse and complex migrations with 62+ supported data sources compared to TransVault’s 29+. And since ArchiveMASH is developed by Bluesource, our team can modify existing or build new connectors without having to wait on third parties. Our connectors span legacy archives, journal stores, and cloud destinations.
Eliminating Pain Points
Traditional data migration software and tools like TransVault rely heavily on local infrastructure dependencies and require installing Lotus Notes clients, local Outlook/MAPI subsystems, or mounting legacy EDB files in live Exchange environments. Additional requirements can slow down a data migration and expose possible compatibility issues.
ArchiveMASH eliminates these pain points:
- No Notes Client or MAPI required: Streamlines migration agent deployment and removes OS/application bottlenecks.
- Native EDB processing: Extract directly from Exchange Database files without the overhead of mounting them to a server first.
Handling Corrupted and Encrypted Data
Migration projects frequently hit roadblocks when encountering corrupted, legacy, or encrypted data:
- Malformed Domino Data: While TransVault flags malformed data as a hard failure, ArchiveMASH is engineered to always attempt to process malformed data as seamlessly as possible. While some data truly is malformed, ArchiveMASH has a strong record with processing certain message and data formatting issues and preserving workflow continuity
- Encrypted NSFs to Microsoft 365: ArchiveMASH natively processes encrypted NSF files straight to M365, avoiding the expensive custom development required by TransVault.
The team behind ArchiveMASH has faced roadblocks before, from complex and large-scale migrations. For a recent project, our team modified an ArchiveMASH connector to overcome an issue with expired encryption certificates and 200+ TB of encrypted data to move.
Uncompromising Security & Privacy
Data security and defensibility are non-negotiable. ArchiveMASH does not store temporary data on intermediate storage drives during processing, significantly lowering risk exposure and easing compliance audits under ISO/IEC 27001 standards.
Additionally, ArchiveMASH utilizes Office 365 migration protocols fully supported by Microsoft, ensuring long-term stability and platform compatibility.
Success Story
A client approached Bluesource with a challenge. They were moving 200TB of data in encrypted mailboxes from Microsoft Exchange to Google Workspace. Their internal policies meant the encryption certificates expired, and Google automatically rejects messages with expired certificates.
The ArchiveMASH connectors we already had couldn’t fully address the scenario, so our team got to work modifying our connectors. The migration finished on schedule with zero data loss, no business disruption, and a full chain of custody.
