This paper deals with the adaptation process of Intra-European South-South migration. The case study focuses on Italian mobility to the South of France with a focus on the PACA (Provence-Alpes-Côte d’Azur) region. This paper aims to analyze the developmental perception of adaptation in migration and the traces left on social networks. Data were collected from an online group on Facebook as a rich interpersonal and social bonding space and narrative accounts of young Italian workers on a website. The posts and narratives were qualitatively analyzed from a dialogical and cultural perspective. Data from the online network revealed the need of the community to share and build knowledge before the migration and right after and during the stay, reconstructing a polyphonic social reference of belonging. In the narratives, the external positions addressed and shaped the process of adaptation during the migration.
