Embodiments relate to methods (900) and apparatuses (800) transferring a first event detector process of a first node (704-1) of a distributed computing system (300; 700) to a second event detector process of a second node (704-2) of the distributed computing system (300; 700), the second node (704-2) being different from the first node (704-1). The apparatus (800) comprises means (802) for copying a process content of the first event detector process to the second event detector process, means (804) for coordinating input events of the first event detector process such that the input events of the first event detector process are processed in parallel at both the first and the second event detector processes, and means (806) for verifying whether the input events of the first event detector process, which are processed in parallel at both the first and the second event detector process, lead to identical output events at both the first and the second event detector processes.
