A practical DNS and email cutover checklist for WordPress migrations, covering TTL, A records, MX records, SSL, propagation, and rollback.
WordPress Migration DNS and Email Cutover Checklist migration tutorial showing backup, transfer, verification, and DNS cutover checks

DNS and email cutover planning can move WordPress safely when it matches the source, destination, and risk level. This method is best for avoiding downtime, split traffic, broken email, and SSL surprises during a WordPress host change.

Audience: business owners, agencies, hosts, and IT teams launching a migrated WordPress site. Before using this path, decide whether the move changes hosts, domains, DNS, email, PHP versions, database versions, cache layers, or business data. Those details matter more than the migration button itself.

Before migration

  • Find who controls DNS and registrar access.
  • Lower TTL before the move when possible.
  • Record current A, AAAA, CNAME, MX, TXT, SPF, DKIM, DMARC, and verification records.
  • Confirm whether email moves with the website or stays where it is.

Migration steps

  1. Prepare the new WordPress site and verify it before DNS changes.
  2. Install SSL on the new host.
  3. Change only the records required for the web cutover unless mail is intentionally moving.
  4. Keep old hosting online through propagation.
  5. Watch logs and analytics for traffic split.
  6. Rollback DNS if the new site fails critical checks.

Post-migration verification

Confirm public DNS, SSL, web pages, wp-admin, forms, email delivery, contact forms, transaction emails, and that both old and new servers are monitored during propagation.

Also check server logs, PHP errors, WordPress Site Health, cache behavior, CDN routing, redirects, robots/indexing state, cron jobs, and whether a new backup job exists on the destination.

Migration risks

  • Changing nameservers can unintentionally move mail records.
  • IPv6 AAAA records can send visitors to the wrong server.
  • DNS propagation can split orders or form entries if dynamic sites are not frozen.

Rollback and cutover planning

Keep the old site online until the new site is proven. For stores, memberships, bookings, LMS sites, directories, and lead-generation sites, plan a final data freeze or sync so records do not split between servers. Keep DNS rollback notes, old-host access, and a verified backup until traffic and logs are stable.

Fix I.T. Phill recommendation

Use DNS and email cutover planning when it gives you the cleanest preview and rollback path. If the site makes money or stores customer records, treat the final cutover as a maintenance window, not a casual copy job.
