Transfer a Domain Without Downtime — Complete Migration Guide

What happens during a domain transfer?

A domain transfer moves the sponsorship and retail management of a domain from one registrar (e.g. GoDaddy, Namecheap) to another (e.g. dnbx.de).

Transferring does not automatically shut down your website or email. If performed in the correct sequence, a transfer completes with zero seconds of downtime.

Pre-Transfer Checklist

Complete these 5 checks before initiating the transfer:

1. Check the 60-day ICANN Lock: ICANN rules prohibit transferring gTLDs (.com, .net, .org) within 60 days of initial registration or a previous transfer. (Note: Many ccTLDs like .de do not have this restriction).
2. Verify the Registrant Email Address: Transfer authorization emails and tokens are sent to the administrative/registrant email address listed on the domain. Confirm you have full access to that inbox.
3. Disable Transfer Lock: In your current registrar's control panel, disable the registrar lock (status: clientTransferProhibited).
4. Obtain the Auth-Code (EPP Key): Request the authorization code (also called Auth-Info code, EPP token, or secret key) from your current registrar.
5. Lower DNS TTLs: If you plan to change nameservers alongside the move, lower record TTLs to 300 (5 minutes) at least 24 to 48 hours beforehand.

 5. Domain arrives in new account ─────────────────────────►

1. Initiate transfer at the new registrar

Log into your new registrar account (e.g. dnbx.de), select Transfer Domain, enter your domain name, and paste the EPP Auth-Code.

2. Approve authorization requests

Check your email. Depending on the TLD, the registry or gaining registrar sends an authorization link. Click to confirm.

3. Registry processing

The losing registrar receives the transfer request. They typically give you 5 days to cancel. Most registrars offer an "Approve Transfer Immediately" button in their dashboard to speed this up to just a few minutes.

How to guarantee ZERO Downtime

The secret to a seamless migration is separating Registrar Transfer from Nameserver Hosting:

1. Keep Nameservers External: If your DNS is hosted on independent authoritative nameservers (such as one.ns.ternis.net and two.ns.ternis.net), moving registrars changes nothing about DNS resolution. Resolvers continue querying the same nameservers throughout the entire process.
2. Handle DNSSEC Carefully: If your domain uses DNSSEC, the parent registry publishes a DS (Delegation Signer) record.

• If the losing registrar deletes the DNSSEC keys when releasing the domain, global recursive resolvers that validate DNSSEC will fail with SERVFAIL (bogus zone).
• Either disable DNSSEC 24 hours prior to the transfer and re-enable it at the new registrar, or immediately submit your new DS record at the new registrar as soon as the domain lands.

Verification commands

After the transfer finishes, verify that your nameservers and domain status are correct:

# Check WHOIS status (should show OK or clientTransferProhibited once re-locked)
whois yourdomain.com | grep -E "Registrar:|Domain Status:"

# Confirm nameservers respond accurately
dig @one.ns.ternis.net yourdomain.com +short
