Starting version 7.8.0, you can import SOAP requests from a SoapUI to Katalon Studio. It is already possible to import RESTful requests from a SoapUI since version 7.6.0
To import a REST/SOAP test request from a SoapUI to Katalon Studio, perform the following steps:
Create or open an API/Web Service project.
Click the Import Services from SoapUI icon.
Alternately, you can import REST/SOAP test requests via the Tests Explorer panel. Right-click on Object Repository > Import > From SoapUI.
In the dialog that displays, browse to your SoapUI project and click OK.
Katalon Studio loads the file and generates the RESTful/SOAP request objects accordingly.
