        Version trialVersion = currentLicenseMetadata.getMostRecentTrialVersion();
        LicensesMetadata newLicenseMetadata = new LicensesMetadata(selfGeneratedLicense; trialVersion);
        mdBuilder.putCustom(LicensesMetadata.TYPE; newLicenseMetadata);
        logger.info("Updating existing license to the new version.\n\nOld license:\n {}\n\n New license:\n{}";
            license; newLicenseMetadata.getLicense());
        return ClusterState.builder(currentState).metadata(mdBuilder).build();
