I'm working with a domain registered with GoDaddy. The client has a WiX website so in GoDaddy they've set custom nameservers to point to ns4.wixdns.net etc. We're deploying a new website on a different server so I want to lower the TTL so I can point the DNS quickly when we get to go-live.
My question is this, if I change the nameservers in GoDaddy back to "Default" (presumably GoDaddy's own nameservers) will all the DNS records be maintained?
i.e. the current website won't become inaccessible due to the A record disappearing when I change the nameservers back to GoDaddy, right?
No, they will not be automatically transferred over, and the website will become unavailable. You need to duplicate the records yourself before switching over.
