What’s the safest way to change a site’s primary domain?

Asked on Sep 24, 2025

Answer

Changing a site's primary domain involves updating several configurations to ensure a seamless transition. This typically includes updating DNS records, server configurations, and any hard-coded links within the site. Here's a structured approach to safely change a site's primary domain.

Example Concept: To safely change a site's primary domain, first update the DNS records to point the new domain to your server's IP address. Then, configure your web server (e.g., Apache or Nginx) to recognize the new domain by updating the server block or virtual host settings. Ensure all internal links and references within the site are updated to the new domain. Finally, set up 301 redirects from the old domain to the new domain to maintain SEO value and user access.

Additional Comment:

Back up your site and database before making any changes.
Update the DNS A record to point the new domain to your server's IP.
Modify the server configuration files to include the new domain.
Check for any hard-coded URLs in your site's content and update them.
Implement 301 redirects from the old domain to the new one for SEO continuity.
Test the new domain thoroughly to ensure all links and resources load correctly.
Monitor the site for any issues after the switch, especially in terms of traffic and SEO.
