Before you start

Take a full backup (files + database) and note your current PHP version, active plugins, and DNS settings.

Step-by-step

  1. Set up the new host first — install WordPress or use a migration plugin's connector before touching DNS.
  2. Clone files and database using a plugin like Duplicator/All-in-One WP Migration, or your host's built-in migration tool.
  3. Test on a temporary URL or via a local hosts-file edit so you can verify the new copy works before going live.
  4. Lower your DNS TTL 24–48 hours in advance so the eventual cutover propagates fast.
  5. Cut over DNS, then monitor the old host for a few days in case of any propagation delays.

Common mistakes

  • Forgetting to update hardcoded URLs in the database.
  • Not testing contact forms and payment integrations on the new environment first.
  • Cancelling the old hosting plan before DNS has fully propagated.
