Change Main-website

Hey there, i’ve made a mistake i think.

I’m developing my website on a testversion to not interrupt the current flow of our users.
Since you can’t have more than 1 release candidate. I copied my main-website and worked on it from there.

Is there a way to change my testsite to the current website?

Go to: https://manage.wix.com/account/domains
Click the 3-dot menu next to the domain.
Choose Assign-To-another-Site.

Note:
I would not recommend to mange your development cycle this way.
Connecting a new site may take some time + you’ll have to export and import the database collections from one site to another (which is a process that might cause issues).
