The LCLS-II is a CW X-ray FEL covering a photon spectral range from 0.2 to 5 keV that is being constructed at the SLAC National Accelerator lab. The FEL is based on a 4 GeV SRF linac installed in the 1st km of the SLAC linac tunnel. This talk will discuss the status of the LCLS-II and describe a high energy upgrade, referred to as the LCLS-II-HE. The LCLS-II-HE will increase the beam energy to 8 GeV and the photon spectral range to 12.8 keV; this range may be extended through 20 keV with improvements of the electron injector and beam transport. The talk will describe key challenges of the upgrade and will also discuss R&D towards further performance enhancements.
