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, wherein the protocolled communications contain the time when the services communicates to other components of the system and wherein dependencies among all applications of the services result in chronologically ordered sequences of service activities sorted by the protocolled time, whereby the services activities are separated from each other by one or more sequences of inactivities of all services; 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, wherein a suitable time slot means that all services are inactive at the same time; 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; and e. enable the control (Ctr) of the deployed update version of the service within the current technical application. La présente invention concerne un procédé mis en œuvre par ordinateur pour mettre à niveau et/ou mettre à jour au moins un service d'une pluralité de services réalisés sur un système (T) mis en œuvre par ordinateur, la pluralité de services mettant en œuvre une application technique commune dans ledit système, le procédé mis en œuvre par ordinateur étant configuré pour: a. déployer au moins une version de mise à jour (Vx) du ou des services qui nécessite une mise à jour ou une mise
