Can someone tell me how I can change the ownership of scheduled searches in Splunk Cloud?
I don't believe we have a way in the UI to do this, so it most likely will be a request to Splunk Support to do so on your behalf. The process is similar to resolving orphaned searches if a user is removed:
so changing the local metadata and a refresh of splunkd would take care of it. However, changing the local metadata is a CLI thing, which one does not have access to in Splunk Cloud.
NOTE: Resolving orphaned objects is something that will be included in the UI in a near future release.
