The Linac Coherent Light Source (LCLS) has been undergoing upgrades for several years now through at least two separate major projects: LCLS-II a DOE 403.13b project responsible for upgrading the accelerator, undulators and some front-end beam delivery systems, and the LCLS-II Strategic Initiative or L2SI project which assumed responsibility for upgrading the experiment endstations to fully utilize the new XFEL machine capabilities to be delivered by LCLS-II. Both projects included scope to design, install and commission a control system prepared to handle the risks associated with the tenfold increase in beam power we will eventually achieve. This paper provides an overview of the new control system architecture from the LCLS-II and L2SI projects and status of its commissioning.
