Migrating archived emails from unsupported legacy systems

Our client recently acquired another company running Enterprise Vault V9 with 25TB of archive data. The client was running Archive Manager 5.1.

The version of Enterprise Vault was old, was without software maintenance and was in an unhealthy state. We needed a tool to extract the data from the legacy system (Enterprise Vault) and migrate it into Archive Manager. That state of the legacy system was such that we could not use the native tools to export the data.

Migration Challenges

The Enterprise Vault server was on an old 2003 x86 which meant the client was unable to add any more resources to the server. The application had been left alone for many years and there was also no longer anyone within the business with Enterprise Vault skills or training.


Redman Solutions introduced our client to Archive360. The Archive360 email archive migration solution allowed the client to extract the data without needing to worry about the state of Enterprise Vault. We used the new x64 bit server with much more resources than possible with the old Enterprise Vault.

Our client was also in the process or re-hydrating the stubbed emails into Exchange to ensure their users had an improved user experience. Using the Archive360 V2 PowerShell integration, they were able to develop their own scripts which allowed them to automate the extraction of the Enterprise Vault archives to PST files.

The final step was to upload the PST files into Archive Manager. One PST was created for each mailbox.


Using Archive360, our client was able to extract all the data from Enterprise Vault without impacting the application, or requiring Enterprise Vault to be bought into a healthy state.

Given the age of the Enterprise Vault hardware and absence of internal team member's knowledge of the legacy system, Archive360 saved the client a lot of cost and time.

Redman Solutions has been supporting Archive Manager for over a decade with migration, licence renewals, annual support, managed services and extractions.
