New to Webflow: Theme / Site Replace Guidance

Hi, i am new to Webflow. i need some advice please.

I already have my site here at Webflow. I want to buy a template. What’s the best way to do this:

  1. Buy the template and apply to my site
  2. Start a new site with the template, move my content, then delete the old site?
  3. Something else?

Thanks, all. Appreciate the help.
