Cloning App and Reverse Engineering

Hi. Hoping someone can help. I just built and app with lots of integrations over the last 2 months and will be building a very similar app. Instead of starting from scratch, is there a way to copy the complete file / zip and reverse engineer it? Also, how do I copy the complete file from my current app and move it into a new project? I’m also thinking about separating the 2 and opening up a brand new replit account on an individual pro plan. How would this work?
