The CMS experiment at the LHC has started data taking in Run 3 at a pp collision energy of 13.6~TeV. In preparation for Run 3, detector systems, such as Pixel Tracker, HCAL and CSC, have been upgraded due to radiation-induced detector aging or to improve performance. A new GEM muon detector layer was also installed. The High Luminosity LHC, will provide unprecedented high luminosity and pileup conditions which require more extensive upgrades under the CMS Phase-2 upgrade project. Fully new tracker and high granularity endcap calorimeter will be installed, as well as additional muon detectors and MIP timing layer. Most current detector electronics will be replaced to handle higher triggering rate of up to 750 kHz and increased latency. The upgrades performed for Run 3 as well as planned Phase-2 upgrades and their current development status are summarized.
