I had exported one of the spaces in my confluence server instance in zipped xml format. When I'm trying to import this space in my cloud instance I'm getting an error - 'Could not locate exportDescriptor.properties in the archive'.
In my exported space I'm unable to find this file.
Below is the content of my exported space. Under the DCP (my space name) folder I can find attachments, images and html files.

I'm not able to use the migration assistant app as I'm not having the admin privileges. Is there a way to perform the migration from server to cloud apart from space export/import and the migration assistant app?
