Abstract: The LCLS II Project is now in full production and installation of the accelerator, FEL and end-user systems, with a scheduled completion date of December 20, 2019, when LCLS II will be handed over to the commissioning team. The existing Cu Linac is undergoing a major upgrade, while the new, superconducting linac is a newly built system. As part of this installation, there are two undulator systems that are being installed: one operating at Soft X-ray (SXR) and the other at Hard X-ray (HXR) wavelengths. The SXR undulator system will deliver photons with energies between 200 - 5000 eV, and the HXR undulator system will in turn, deliver photon energies ranging 1000 - 25,000 eV. The SXR undulator system is composed of 21 linearly installed undulators, while the HXR undulator system will have 32 linearly installed undulators, both systems installed side by side. Each undulator will be integrated with a complement of interspace instruments composed of an RF beam position monitor, quadrupole magnet, beam loss monitor, phase shifter and with a contiguous vacuum system composed of undulator vacuum chambers, interspace spools, valves and pumps, and drift lattices. It is noted that the infrastructure and cable plants for the undulator systems are almost complete and initial undulator system installations have just commenced. In this presentation, the current status of both undulator systems will be discussed, including their design and component performance, but also discussed will be some of the pitfalls and "lessons learned" during the project.
