Running selenium webdriver scripts through Katalon studio

We are are automating some of our projects using Selenium web driver and some projects using Katalon studio. Our management wants to use a single tool across the organisation for easy maintenance.
Can you please let me know whether we can run our web driver scripts through Katalon (Not selenium IDE scripts)?
If it is possible, what changes we need to make to our selenium scripts and how to invoke them from Katalon? Need to use TestNG or other frameworks to open Selenium web driver scripts in Katalon?

Thanks in advance.
