I’m using Register4Less as my domain registrar at the moment and I want to transfer to Cloudflare, although I’m already using Cloudflare DNS and Cloudflare provided SSL.
After I transfer the domain to Cloudflare, will I have to update the DNS records? I couldn’t find any docs for that, unfortunately.
However, some registrars like to give you a little present, by resetting the NS records in the Registry just before the transfer. If this happens, open a support case, and drop the domain and ticket number in this thread.
