Moving a live site can be stressful, but with the right workflow, you can migrate website to Linux VPS without downtime by preparing the new server, testing the configuration locally, and switching your DNS records.
In this guide, you will learn to move your website files and database to a new Linux VPS safely, so that visitors can access it online.
Before you start the migration, you must confirm you have everything required on both the source server and your target VPS.
If you need a new Linux server, you can check PerLod Hosting, which offers affordable Linux VPS plans.
Once you are done with the requirements, proceed to the following steps to migrate a Website to a Linux VPS without downtime.
Before moving anything, you must archive your web files and export your database to guarantee data integrity. Connect to your old server via SSH and navigate to your website's root directory.
Compress your web files with the command below:
To export your MySQL or MariaDB database, you can run the command below:
Instead of downloading files to your local machine, you can use rsync to transfer them directly between servers for maximum performance and efficiency.
From your old server, run the command below to transfer files and the database:
Once you copied the files with rsync, log in to your new VPS via SSH to extract the files and import the database into your pre-configured empty database.
To extract the files directly into your new document root, you can run the command below:
Then, restore the database with the following command:
Finally, fix the file ownership so your web server can read them:
The www-data is the default web server user and group for Nginx and Apache on Ubuntu and Debian systems. If you are using a RHEL-based distribution like AlmaLinux or Rocky Linux on the new server, you must use one of the following, based on your web server:
Before pointing your live domain to the new VPS, you must verify that the site works perfectly on the new server. You can privately view the site on your new server by updating your computer's local hosts file.
For Windows, you must edit:
For macOS and Linux, you must edit:
Add this line at the bottom of the file:
Save the file, flush your DNS cache, and open your browser. You are now secretly viewing your site on the new server. Navigate through the pages to verify the database works and images load correctly, and then remove the line you added when you finish testing.
If you run a busy site like a store or forum, run the mysqldump and rsync commands one more time to catch any final changes before going live.
Once everything is verified, update your DNS records to route global traffic to the new server:
Since you tested everything before updating DNS records, visitors on the old server and those already hitting the new one will see the same site throughout the switch without downtime.
Moving a live website doesn’t have to cause downtime. Set up the new server first, copy your files and database with rsync and mysqldump, and test everything using your local hosts file before changing DNS. After you update the A record and DNS finishes updating, your site will run on the new Linux VPS without downtime.
