There are a couple of easy ways to redirect your traffic.
You can use a simple re-direct in cPanel to direct all traffic to the Wix URL. You can enter cPanel via ClientZone from the Hosting section, and the selecting Redirects in the Domains section of cPanel.
You can also edit your DNS records in ClientZone to reflect the IP address or URL provided by Wix for your DNS records to direct traffic directly to the site you have hosted with them. You can do this by choosing the Hosting option in ClientZone the clicking on Hosting Settings and DNS Editor.
To change your NS records, you'll need to mail us below as specified, and ensure that you receive valid nameservers from Wix to use their nameservers to direct traffic directly.
