Slick, One-step Migrations

Migration is direct from EAS to Office 365 – there’s no interim stages or file formats that add time, complexity and risk to your move.

Unbeatable Office 365 Ingestion Speeds

TransVault’s state-of-the-art connectors into EAS and unique TransVault™ CloudStream technology ensure you get optimum on-boarding performance into Office 365 – with minimal impact on your network or legacy archive.

Minimize What you Move

TransVault offers advanced selection criteria to determine what data gets migrated – minimizing your migration times, yet enabling you to defensibly omit data from your move.

You can also direct emails to either primary Office 365 mailboxes or In-Place Archives as required.


As you migrate, legacy EAS shortcuts (stubs) are cleaned up and replaced with the original email held in EAS (with support for both Exchange and Notes format conversion).

TransVault also synchronizes with the users’ current mailbox view, ensuring migrated emails end up in the right Office 365 folders and that all the relevant users can still see the emails they had access to ‘pre-migration’.

Preserves Chain-of-Custody & Integrity

In addition to being a single, end-to-end data transfer (preserving chain-of-custody), each and every item migrated is fully audited, enabling you to meet business and compliance needs relating to secure email records retention.  You can also move journal (compliance) archives into Office 365 ensuring the vital metadata required for eDiscovery (i.e. Bcc’d and distribution list members) is preserved and mapped into the new Office 365 compliance model.


TransVault was the first ever solution available for migrating emails out of EAS and supports versions of EAS delivered via Educom, ZANTAZ, Autonomy, HP and now Capax.

The solution continues to deliver the most proven EAS migration solution and can satisfy the most demanding technical, compliance and business needs.
