Noticed that in the option for importing test scripts in RQM it does not have the Manual.

Is it possible to import manual test scripts into RQM?

Or is it only possible to import automated scripts?

Or do I need to import via the backend?

You are correct that the "import test scripts" option in the WebUI is for automated scripts only.

It wouldn't make much sense (in my opinion) to have an "import manual test scripts" option in the WebUI. Any such function would have to be reliant on the scripts being in a specific format.

Where are you importing the scripts from? A few options to consider:
* If the scripts are in RMT, use the included RMT -> RQM migration tool.
* If the scripts are in TM's ManualTest, use the included TM -> RQM migration tool.
* If the scripts are in Excel or Word documents, use the included MSO2RQM migration tool.
* If the scripts are in some other format (and you cannot easily convert them to one of the above formats), you could write your own utility utilizing the RQM REST API.
