Hey Ziggy - I've done the above, duplicating all the info on my site that I want to use to publish my site live. But I now have three "sites" (a primary site with my domain that I want to use, a sandbox site that I built all my content on, and a copy of the sandbox site) and can't figure out how to migrate the site I've built on my sandbox page to my active domain page.
I basically just want to move the content here: https://burgundy-mushroom-wszw.squarespace.com/
on to here: https://www.davidwainer.com/
Any help is appreciated.
