MHSCT SourceOne Migration

Project Details

Customer Sector
6200 User Archives
Archive 360
Services Delivered:


A local NHS trust had a requirement to extract part of their archived data, currently held in EMC SourceOne, out to PST.

The engagement was carried out remotely as a managed service using server hardware provided by the client to build and run the migration application environment. Working with the client a list of user archives was provided and migration priority determined by the client in accordance with which users were currently active on the domain.

A 2-year cut off was set for the migrated data, therefore only archived data under 2 years old was migrated to PST. There were some exceptions to this which were dealt with at the end of the project and all of those users archived data was migrated.

About The Engagement

The entire technical engagement was carried out remotely to save time and reduce costs to the client. This allowed for flexible interaction with the environment, as and when required.

After initial workshops had been held the environment sizing information was detailed to the client in order for them to provide the necessary server hardware, storage and user accounts assigned with the correct permissions to access the archived data.

Having connected the migration server to the SourceOne environment an initial migration pilot was carried out using nominated user archives provided by the client.

At this stage it was evident that there was an underlying issue with the SourceOne environment that was causing serious performance implications on the migration process. TrueSwift worked with the client to identify the problem and help provide a change to the maintenance procedures in operation on the SourceOne environment to help improve migration performance successfully.

Following the successful pilot the remaining SourceOne user archives were migrated to PST. In total approximately 6200 user archives have been migrated with a total of 17.7 million messages. In total approximately 2.3TB of archived data was migrated to PST.


  • TrueSwift delivered a plan to achieve the migration of over 2TB of archived data from SourceOne to PST. The customer received expert knowledge pertaining to this type of project.
  • The customer objectives were achieved in a timely manner.
  • The customer received a flexible approach to the migration that fitted in with the demands of their day to day working.
