Before you start:

  1. Backup Current DNS Records
  2. TTL Adjustment (Lower the Time-To-Live (TTL) for your DNS records to a short duration (e.g., 300 seconds) a few days before migration. This allows changes to propagate faster during and after the migration.)

Step you may find helpful :

  • Set up Route 53 Hosted Zone. (Create a new hosted zone in Route 53 for each domain you are migrating.)
  • Replicate DNS Records. (Manually replicate all existing DNS records (A, CNAME, MX, etc.) in the Route 53 hosted zone. Double-check for accuracy.)
  • Verify Records. (Use Route 53's "Check DNS" feature to verify that your records match your expectations.)
  • Update Name Servers.(Update the name server records at your domain registrar to point to the Route 53 name servers.)
  • Wait for DNS Propagation : (DNS changes take some time to propagate globally. Monitor the propagation using tools like dig or online DNS checking tools.)
  • Test with a Subdomain (Test the migration by updating the DNS for a less critical subdomain first. This helps you identify any issues before updating the main domain.)
  • Update Main Domain (Once you're confident in the migration, update the DNS records for your main domain.)
  • Monitor for Issues.

  • You're welcome.

    Why would you need to set up end-users' devices for public DNS?

    Just keep in mind, the responses provided earlier are general in nature and based on your first question. If there are additional crucial details specific to your environment, it's advisable to either explicitly mention them or seek guidance from a dedicated resource to ensure a comprehensive approach to the migration process.
