To transfer your website to a new domain, first, register and set up the new domain with hosting. Backup your site by downloading all files and exporting the database. Next, upload these files to the new domain's hosting and import the database. Update your site's configuration to reflect the new database settings and domain URLs. Set up 301 redirects from the old domain to the new one to maintain SEO and traffic, then verify that everything functions correctly on the new domain. Update DNS settings if needed, and notify search engines by submitting a new sitemap and using tools like Google Search Console to indicate the change.

After registering your domain, choose a hosting provider and set up your account. Update your domain’s nameservers to those provided by your host. Upload your website files or install a CMS. Optionally, set up email hosting and secure your site with an SSL certificate. Test your website, submit it to search engines, and keep it maintained.
