Migrating data to new core systems for O2

Within O2’s extensive project called Simple Online Company (SOC), Profinit provided within the Big Data services a detailed plan and prepared and implemented data migrations from 10 discarded or modified applications to 7 newly running systems. The migration consisted not only of a physical movement of the data but also of sophisticated data transformations due to a different logic of the systems, product portfolio simplifications or cancellation and creation of tens of tariffs, customer packages and other additional services.
