Replacing a current project with an new one under same workspace

[Jakes]

Hi, I have a Unity project that I have been working on for about a year, I have been making commits regularly using the Plastic SCM windows desktop app. 

I am wanting to restart the project (a new unity project), and completely delete everything from the previous project (local files and cloud history). I want to do this within the same workspace as the previous project so that I can commit files from the new project. 

Is this possible? Is this a bad idea?

 

Thank you.
