How to Migrate Your Website to a New Host Without Downtime

How to Move Your Website to a Different Host Without Downtime: Step-by-Step Guide
Changing your website’s web hosting provider is like having open heart surgery on your business. A single mistake during the transfer of files and DNS change can lead to broken database connections, dropped e-commerce transactions, destroyed search engine rankings, and thousands of your customers receiving server error messages of level 500. However, staying with an unproductive host out of fear is as harmful to your business as making a mistake in moving a website.

The good news is – moving your website doesn’t have to entail downtime. With a solid staging strategy and DNS management practice, a zero-downtime website migration is a piece of cake. Let’s see how to migrate a website with minimal risk in this step-by-step guide covering the whole process from backup to testing SEO.

1. Zero-Downtime Migration: The Basic Principles
Financial and SEO Consequences of Unexpected Downtime
Every moment your website is down during the migration affects not only your bottom line but your SEO rankings too. Search engine bots (Googlebot) crawl your website on a regular basis. If they face connection failures due to the migration process, then there is a chance that your page will be dropped off the SERPs for a while, causing loss in domain authority and organic traffic.

The Core of a Smooth Transition
Zero-downtime migration means running two web hosting environments simultaneously until your new server is fully configured and working. Unlike traditional migration when your old host is shut down before the transfer of files, a zero-downtime migration implies creating an exact copy of your website on a new host while keeping the original one alive. As soon as the new website is tested and verified, you redirect the whole traffic to it through DNS management.

2. Pre-Migration Checklist: Preparation of the File and Environment
Website Hosting Environment Audit
Before you start migrating files, audit your current website infrastructure. Note the technical parameters of your hosting including PHP version, database engines (MySQL, MariaDB), memory limits, cron jobs, and any custom modules (mod_rewrite, Imagick). Make sure your new hosting supports them to prevent script malfunction after moving.

Backups of Website Files and Databases
Moving without proper backups is like cutting yourself with a dull knife. Always have a full set of your website backups prior to starting the migration process. Back up both main components of your website:

Files: Download all core files, media libraries, scripts, and configurations via SFTP/SSH.
Databases: Export all your website databases using PHPMyAdmin or Command Line Interface (CLI). For bigger databases, use direct compression on the server side to avoid timeouts. If you work with WordPress, make sure to consider top-notch WordPress backup solutions.

3. Website Staging on the New Host
Upload Techniques of Files and Databases
Now when you have backups of your site safely saved, log in to your new hosting control panel (cPanel, Plesk, etc.) and upload core files of your website and extract them to the web directory (usually public_html/www). Next, create a new database on the new host, create a database user and grant it full privileges, and finally import your SQL database file there.

Configuration of the Database Connections
After uploading your database, update the configuration file (wp-config.php for WordPress and configuration.php for Joomla) with credentials of the new database:

Database name (DB_NAME): enter your new database name
Database user (DB_USER): enter your new database username
Database password (DB_PASSWORD): enter your new database password
Database host (DB_HOST): normally, localhost should do, but some hosts require a custom endpoint
Refer to official guides on site changes in case you need further technical details.

4. Previewing Website Before DNS Change
Editing the Hosts File on Local Computer
Most webmasters make a huge mistake and change their DNS records before testing the new server. But this is easy to be done via editing your local hosts file (C:\Windows\System32\drivers\etc\hosts on Windows and /etc/hosts on macOS/Linux):

192.0.2.45 example.com www.example.com

Save the file and flush the DNS cache. Now, when you visit your website in the browser, your computer loads your website directly from the new host while all the other visitors still continue visiting the old host. Make sure to test your logins, form submissions, e-commerce payments, and all links.
