Hi Martin,
As Pubudu explained, those are the expected steps and the result of the
application update. *Application Runtime* can only be updated with
cartridgeMin/cartridgeMax and/or with groupMinInstances/groupMaxInstances.
Even if you update other parameters, it will get ignored by the back end.
Please note that you can update application only when it is in deployed
mode. After application is created, if you need to update, then you will
have to delete the application and create it again. Currently application
update is not available when the application is in created mode.
Thanks,
Reka
