AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is an experiment at the Antiproton Decelerator (AD) facility at CERN whose goal is to study the asymmetry between matter and antimatter and, in particular, the effect of the Earth's gravitational potential on anti-hydrogen. During the run in 2018, anti-hydrogen formation was achieved, leading to considerable gain of knowledge on the processes involved. In the meantime, a new decelerator, ELENA, has been introduced, changing the beam received. Therefore, in the last two years, during CERN Long Shutdown 2, multiple upgrades to the experiment have been carried out, spanning from new degraders, a new Hbar formation trap scheme, an entirely new control system, a more efficient positron accumulation line, two new lasers and a laser hut, and more efficient sensors. This work is necessary towards the goal of creating the first pulsed beam of neutral antimatter, which will enable us to perform inertial studies on antimatter with high degrees of precision. In this contribution I will present the different upgrades, the validation of the new approach with beam, and the further developments foreseen in the future.
