Command Central Command Line Tool Upgrade
In all existing Integration Server automation scripts and queries that use the Command Central REST API or command line tool commands, change the Integration Server instance ID for all Integration Server instances from:
runtimeComponent=integrationServer-ENGINE
to
runtimeComponent=integrationServer-instanceName
where instanceName is the name of the Integration Server instance, for example integrationServer-default.
