1. A method for automigrating electronic data in a networked environment from a source storage device to a target storage device, comprising:

  • reading, into a memory of an automigration controller, configuration parameters characterizing at least one of hardware or software properties of the source storage device, the target storage device, and a network connection between, the source storage device and the target storage device;

    deriving fuzzy variables from values of the configuration parameters;

    feeding a predetermined fuzzy function with the fuzzy variables, wherein the fuzzy function reflects the exhaustion level of the source;

    executing the fuzzy function yielding a fuzzy result value;

    applying the fuzzy result value to a control scheme, yielding a control result; and

    controlling at least one of start, stop, or bandwidth of automigration of data based on the control result.
