+=== Change server for asynchronous processing (switch application instance) ==
+@since 11.1.0
+Application instance (server) is used for asynchronus processing - for scheduled tasks, asynchronous long running tasks and events.
+Instance identifier can be defined in the application profile (application.properties) by property ''idm.pub.app.instanceId''.
+When we want to schedule and process asynchronous tasks and event on other instace (or when one instance shutdown), then we can switch processing by provided bulk action ''Change server for asynchronous processing'' in configuration agenda:
+{{ :devel:documentation:application_configuration:dev:switch-instance-bulk-action.png |}}
+Previous and new instance identifier is required as input parameters. All scheduled tasks and all created (~ not processed) asynchronous long running tasks and events will be moved from previous to new instance and will be processed on new instance (server).
