Change Nameservers Without Losing Business Email

A nameserver change moves responsibility for answering DNS queries. It does not automatically copy your existing records. If the destination zone contains only a website address, your website may load while email, verification services and subdomains stop working.

Build the new zone before switching

Export the current zone or make a complete record inventory. Include A and AAAA records, www, MX, mail-related TXT records, verification entries and any service subdomains. Compare the new zone against that inventory rather than relying on an automated scan to find everything.

Check the destination's exact nameserver values and whether the zone is ready to answer. Keep a record of the previous delegation. If DNSSEC is active, coordinate the signing and parent DS record with the old and new providers. A stale DS record can cause validation failures even when the website's A record is correct. Follow the providers' migration procedure rather than guessing the order.

Plan a quiet change window

Avoid combining the delegation change with mailbox moves, application upgrades and a redesign. Independent changes make failures harder to isolate. Preserve the previous DNS service during the transition where possible; cached delegation information can send queries to either provider for a while.

• Test the new authoritative answers before the switch.
• Compare website, email and important subdomain records.
• Save the registrar login and a verified support contact securely.
• Tell the team when and how to report service problems.

Verify services separately

After updating the registrar, inspect the delegation and test both incoming and outgoing email. Visit the site over IPv4 and IPv6 where available. If only some visitors have trouble, compare resolver answers before editing the zone again.
