Case Study: T-Mobile achieves seamless billing system migration with PhixFlow

T-Mobile - Customer Case Study

T-Mobile, a leading global mobile communications company, faced the challenge of migrating its legacy wholesale billing system across its UK and German operations before vendor support ended. They engaged PhixFlow to ensure a seamless and timely migration of over 14 million subscriber records to a new system without the risk of running an unsupported platform.

PhixFlow implemented a cost-effective, file-based batch load solution to transfer the data. Their team created the necessary data mappings between the old and new systems and used an iterative process to identify and fix data quality issues at the source. PhixFlow successfully migrated the UK data and then replicated the process in Germany, delivering the entire project on time and on budget while eliminating the significant cost and risk of parallel system operation.
