To import test cases into Qase project, you need to open an "Import" section inside a project:
On that page, you can choose a source and a suite that will be a parent for all imported test cases. If the suite is not defined, all test cases and suites will be uploaded to the root of the project.
To import test cases your role should have "Import" access right.
