  The PSI 590-MeV Cyclotron is already more than 30 years in operation. However, it still holds the world record in continuous beam power. There is an active experiment program being pursued, and new experiments are planned and being built. In addition, the beam intensity is being upgraded by 50%. The control system has been through several incremental upgrades. However, the new requirements and other developments at PSI (other accelerator facilities) force again an upgrade. This time the whole architecture of the system is to be changed. The controls hardware architecture will be changed and the underlying software will move to EPICS. All this has to happen without compromising the operation schedule. In the upgrade program we are planning to benefit from several new developments, both in-house and together with the community. The central technologies to be used will be presented. The issue of how to tackle the somewhat contradictory goals of upgrading on the fly will be discussed.

  Over the last two decades EPICS has evolved from a basic set of control applications created for the Ground Test Accelerator to a rich and reliable control system framework installed in more than 120 locations worldwide. The continuous development of EPICS is supported by the worldwide collaboration and coordinated by a set of major laboratories. This procedure ensures continuous quality checking and thus leads to stable production versions. The clear separation of the robust core software on the Input Output Controllers (IOCs) from the channel access protocol and the applications running on workstations and servers allows nearly independent software developments on all three levels. This paper will describe the new developments on the IOC side, which will increase the robustness by adding redundancy or will improve the management and the functionality. This includes the vision of a new Java-based IOC. The support for new data types will bring more flexibility to the channel access protocol. New developments on the application side are clearly indicating that Java and Eclipse (e.g., Control System Studio – CSS, XAL and others) will form the basis for many future applications.
