The EPICS-based control system, in terms of both hardware and software has evolved significantly over eight years of operation as the rate of experiment delivery has increased through means such as photon-beam multiplexing. A description of the upgrades and improvements to hardware, software, tools, and procedures will be presented. Additional discussion points will focus on: (1) the positive effect of upgrades regarding reduction of staffing levels and required skill-level required to support operations; (2) enabling highly skilled staff to focus on further improvements; and (3) current and future upgrades required to support the LCLS-II which will further expand experiment output when it achieves first light in 2020. LCLS-II topics include requirements for automation of routine tasks such as x-ray and optical-laser beam alignment, and focusing as well as improvements to user-interfaces and user-experience which will allow users and non-expert staff to execute experiments.
