The new E989 Muon g-2 experiment will measure the muon's anomalous magnetic moment, g-2, with at least four-fold improved precision compared to the former BNL E821 result. In order to achieve this new level of precision, many upgrades to the existing experiment have to be done. The current status of the ongoing hardware upgrades will be presented. The g-2 project recently also achieved a major milestone of ramping the reassembled storage ring to the full field of 1.45 T. With this, we are entering into a new phase of many months where the collaboration will shim the magnet to drastically reduce field inhomogeneities. First results of the field mapping and other measurements will be presented as well as steps to improve the inhomogeneities around the 45 m circumference of the storage ring.
