	Running a CW electron accelerator as a user facility for more than two decades necessitates upgrades or even complete redesign of subsystems at some point. At ELBE, the outdated timing system needed a replacement due to obsolete components and functional limitations. Starting in 2019, with Cosylab as contractor and using hardware by Micro Research Finland, the new timing system has been developed and tested and is about to become operational. Besides the ability to generate a broader variety of beam patterns from single pulse mode to 26 MHz CW beams for the two electron sources, one of the benefits of the new system is improved machine safety. The ELBE control systems is mainly based on PLCs and industrial SCADA tools. This contribution depicts how the timing system implementation to the existing machine entailed extensions and modifications of the ELBE machine protection system, i.e. a new core MPS PLC, and how they are being realized.

	The COSY (COoler SYncchrotron) at the Forschungszentrum Jülich is a hadron accelerator build in the early 90s, with work started in the late 80s. At this time the whole control system was based on a self-developed real-time operating system for Motorola m68k boards, utilizing, unusual for this time, IP-networks as transport layer. The GUI was completely based on Tcl/Tk. After 25 years of operation, in 2016, it was decided to upgrade the control system to EPICS and the GUI to CS-Studio, in order to e.g. allow a better automatization or automatized archiving of operational parameters. This was done together with Cosylab d.d. bit by bit while the synchrotron was in operation, and because of the complexity is still ongoing. The experiences of the stepwise upgrade process will be presented and a lessons learned will be emphasized.
