Coordinator and method for providing control applications via a communication network, wherein prior to migrating a flow control component of a control application to a server device, a coordinator checks whether a data stream for transmitting application data was set up for the control application, where the coordinator enables migration of the flow control component if a data stream has not been set up, in the event a data stream had been set up previously, a check is performed to determine whether sufficient resources for data transmission are available for paths to the server device, such that if sufficient resources are unavailable, migration of the respective flow control component is stopped, and if sufficient resources are available, the coordinator prompts set-up of the data stream to the server device and disconnection of the previously set-up data stream and enables migration of the flow control component to the server device.
