Redesigning using a studio template

Question:
How can I redesign my existing website from Wix site to a studio template but do on backend and then copy over to my existing website location?

Product:
Wix Studio

What are you trying to achieve:
I created my website earlier this year using a Wix template but made lots of edits. I didn’t realize the difference between normal templates and studio templates at the time. I asked a pro about some advice and they suggested since I am still early with my business that I recreate using studio template. What is the best thing I can do to create a new website design but then use it to replace my current design? I don’t want to lose the data for products, sales, subscriptions, etc.

What have you already tried:
I haven’t started the process. Looking through templates to see which I like best and will function for how I would like my site.

Additional information:
website is www.therebelwild.com - I am still learning and a very small business. After a recent layoff, I have time to dedicate to try and do this right, but need advice on how to achieve.

Thank you!!

Currently you cant replace a classic wix editor site with a Studio site. You would need to start all over again. There is only limited backend items that can be exported and imported back in.
