Sumario:To prepare the migration to the new ATLAS Data Management system called Rucio, a renaming campaign of all the physical files produced by ATLAS is needed. It represents around 300M files split between $\sim$120 sites with 6 different storage technologies. It must be done in a transparent way in order not to disrupt the ongoing computing activities. An infrastructure to perform this renaming has been developed and is presented in this paper as well as its performances.
