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.
