A method and a system are for determining of the compatibility of control software, which is designed for standard parameters, with a wind energy installation which is operated using operating parameters. The method is an automatic method in which the operating parameters of the wind energy installation and the standard parameters of the control software are first transmitted to a computation unit. The computation unit determines discrepancies between the operating parameters and the standard parameters. A decision on compatibility is made on the basis of the discrepancies. The system includes a logic module which is designed to make the decision. This method makes it easier to automatically update the control software for a wind energy installation. There is no longer any need to manually check the compatibility of the new version of the control software before the new version of the control software can be installed.
