BT Case Study: Complex, Large-Scale, Real-Time Data Migration

Key Objectives

A legally binding commitment to Ofcom to operate in an ‘equivalent’ manner to other service providers using the BT network.


A large-scale and complex data migration to separate BT’s retail operation. Acxiom migrated 12 million accounts with 80,000 product combinations, achieving a migration quality level of more than 99.5% correct at the first attempt.


BT satisfied Ofcom that it can operate in a way that enables fair trade in the telecoms service provider sector, avoiding significant potential fines

Migration to the new data platform has provided BT with greater customer insight, enabling it to deliver personalised and highly targeted customer communications.
