This Linux.com tutorial tries to cover all the bases should you have to move your web site from one provider to another.
The Web site hosting business has become more competitive in recent years. If you can find a better hosting deal, you may be able to save money by switching hosting providers. But what's the best way to move your Web site? What if you have a virtual private server (VPS) hosting several domains? What about PHP and your SQL data? The thought of moving may be daunting, but moving servers is not difficult if you plan properly. Here's how.
A complete migration involves transferring the site data itself, meaning all the HTML and possibly PHP and MySQL files and CGI programs. You also need to modify the Domain Name System (DNS) information for the site and for the routing of the site email. DNS holds information that translates IP addresses to human-readable domain names. For Web site migration, the two important DNS records are the address (A) record, which tells the browser the IP address of the Web server, and the mail exchange (MX) record, which tells mail servers how to route the email.
When you migrate your Web site to another hosting provider, you need to update DNS to point browsers to the new location of your site. However, it can take as long as 48 hours for DNS updates to propagate to all DNS servers on the Internet. Part of your planning will be how to deal with that delay.
Often your domain name has been registered via a third-party domain name registration company. When you move the site, your domain name company remains the same, and only your Web hosting company changes. If your domain name originally came with hosting, you may need to contact your old hosting company to see if you can separate the hosting package from the domain name.
