The VVV/VVVX survey has been monitoring the inner Milky Way with sub- arcsec spatial resolution in near-IR bands for 13 years, and generating 50-200 epoch light curves of hundreds of millions of sources down to Ks~17 mag. This database allows to probe the structure and the evolution of the most obscured part of our galaxy. This is the first survey in the near-IR to cover nearly 80% of the luminous Milky Way mass in such depth and with such unprecedented number of epochs. The goal of the Workshop is to bring together active VVVX Science Team members and collaborators, giving them the opportunity to present their results, to work intensively on the ongoing projects, and to plan future collaborations and follow up studies.
