PST elimination and archiving for European energy producer

64TB PST | 32,000 USERS | EV

One of Europe’s leading energy producers embarked on a project to roll-out Microsoft Windows 7 on new laptops and workstations company-wide. With 32,000 users spread across seven countries it was essential that the project delivered real value and was not simply a like-for-like exchange of technology.


• Strategic rollout of Windows 7.

• 32,000 users, 250 locations, 7 countries.

• Migrate and eliminate old PSTs.



• Quadrotech PST Flight Deck.

• Quadrotech consulting.

• Migration and consolidation into Enterprise Vault.



• €500,000 cost saving.

• 25% reduction in storage.

• Successful migration of 50TB data (145,000 files).

• No interruption to users.


The client needed to address issues with PST files that prevented users from accessing email content using mobile devices and posed significant operational risk with regard to availability and legal discovery. It decided to eliminate user PST files from its environment altogether and move the content into Symantec’s Enterprise Vault email archiving platform.


After investigating options for eliminating PST files the company turned to Quadrotech. PST Flight Deck was used to scope the project and Quadrotech’s consulting team recommended a strategy moving forward. The initial stage of the project identified 145,000 PST files occupying some 64TB of storage located primarily on end-user workstations, laptops and removable devices.


The project was run across four datacenters, affecting users in 250 locations. PST Flight Deck centralized the PST files without user disruption and included automatic verification, password removal and corruption repair. The ability to de-duplicate content at an item level resulted in a 25 percent reduction in storage, and user productivity was increased because there were no longer duplicates of emails.


In addition to the migration of the data, managing the user interaction and expectations were important to success. An intuitive dashboard meant that administrators could always see the latest status and progress. Because users were kept informed, helpdesk calls were kept to a minimum, and from a compliance perspective PST Flight Deck maintained a full audit trail of actions taken ensuring future legal discovery processes would not be compromised.


The client ran a full cost comparison between migrating manually and using PST Flight Deck, which indicated savings of €500,000 over the project. The automation and control it provided meant overall risks were minimized and the project was delivered within a predictable timescale and budget.
