Change Project Type

Hi, 

Can anyone shed some light on how the PS 2013 would behave if I change one of my projects from certain Project type to SharePoint list. How the Project Site and tasks would be impacted?

I dont have a dev environment with me to test it and can't take risk without knowing directly in prodution
