SYSTEM AND COMPUTER-IMPLEMENTED METHOD FOR UPGRADING AND/OR UPDATING AT LEAST ONE SERVICE OF A PLURALITY OF SERVICES

The present invention relates to computer-implemented method for upgrading and/or updating at least one service of a plurality of services performed on a computer-implemented system (T), wherein the plurality of services implements a joint technical application in said system,wherein the computer-implemented method is configured to:a. deploy at least one update version (Vx) of the at least one service which needs to be updated or be upgraded on the system while maintaining the current version of the service on the system, wherein the update version of the at least one service is prevented from controlling specific parts of the joint technical application;b. deploy and operate a monitoring module (A2K) for protocolling communications (IN) among the plurality of services and for analysing dependencies among applications of said services with respect to their running times wherein such dependencies are derived from data resulting from the protocolled communications;c. determine process states (PSt) of each at least one service which are suitable for updating and/or upgrading said service by complying with criteria inferred from said dependencies to identify suitable time slots for updating and/or upgrading the at least one service;d. disable the control (Ctr) of the current version of the service within the current technical application at a time slot of said identified time slots; ande. enable the control (Ctr) of the deployed update version of the service within the current technical application.
