A Comprehensive Migrate WordPress to VPS Guide for Beginners

A live WordPress (WP) website is an active website that is already accessible to visitors, customers, or clients on the internet. A migrate WordPress to VPS process means transferring all of the WP site’s files, database, configurations, and domain settings from a shared hosting to a VPS.

This article explains the procedures in this “migrate WordPress to VPS guide”, from understanding VPS hosting and preparing migration of WP site to a virtual private server. We’ll also discuss setting up the VPS environment, migrating WP files and database, configuring domain and DNS settings, and basic testing and troubleshooting.

Understanding VPS Hosting

What is a VPS?

A VPS is a virtual machine hosted on a physical server. Unlike shared hosting, each virtual private server operates independently with its own allocated CPU, RAM, storage, operating system, and networking resources.

What is the Relation of a VPS to a WordPress Site?

WordPress is a PHP-based content management system that relies on a web server (like Apache or Nginx), a database (e.g., MySQL or MariaDB), and PHP processing in order to function. A VPS provides the ideal environment for running WordPress because you can tailor every aspect of the server to meet WordPress’s specific requirements. Unlike shared hosting, where you’re restricted to the provider’s generic configurations, a VPS lets you optimize the entire track for your specific setup.

Why VPS is Ideal for WordPress Scalability

Scalability is perhaps the most compelling reason to move WordPress site to a VPS. As your website traffic grows, its hosting environment must be able to accommodate increasing visitor numbers and application demands. The advantages of moving your WP site to a virtual private server include:

• Dedicated CPU and memory resources
• Better website performance
• Greater uptime reliability
• Ability to handle traffic spikes
• More control over server configurations
• Easier future upgrades

The benefits in the above list makes WordPress VPS hosting an excellent long-term solution for personal blogs, business websites, eCommerce stores, and membership platforms.

Preparing the Migrate WordPress to VPS Process

Migrate WordPress to VPS Checklist

Your VPS migration checklist primarily involves the factors to consider in selecting the right hosting provider and hosting plan:

• CPU and RAM: WordPress is sensitive to single-core performance. For a blog or corporate site with moderate traffic, 1-2 vCPUs and 2GB of RAM may suffice. For a WooCommerce store or LMS platform, aim for 2-4 vCPUs and 4-8GB of RAM.
• Storage Type: Prioritize NVMe SSD storage, which offers significantly faster read/write speeds than traditional SSDs or HDDs. This directly impacts database query performance and page load times.
• Bandwidth: Estimate your monthly traffic. A website with 10,000 daily visits typically consumes 30-50GB of bandwidth monthly; e-commerce or media-heavy sites may require more.
• Datacenter Location: Choose a datacenter geographically closer to your primary audience to reduce latency.
• Managed vs. Unmanaged VPS: If you’re a beginner with limited server administration experience, a managed VPS is the safer choice—the provider handles server updates, security patches, and technical support. An unmanaged VPS gives you full control but requires technical expertise.

How to Back Up Your WordPress Site (Files and Database)

1) File BackUp:

• Download your entire WordPress directory via FTP or SFTP. For larger sites, use the following command:
  • tar -czf wordpress-backup-$(date +%Y%m%d).tar.gz /var/www/html/tar -czf wordpress-backup-$(date +%Y%m%d).tar.gz /var/www/html/

2) Database backup:

• Export your WordPress database using phpMyAdmin. You can also use the following command:
  • mysqldump -u username -p database_name > wordpress-db-backup.sql
• Ensure the backup includes the “DROP TABLE” option to cleanly overwrite existing tables during the restore process.
• Verify that the backup files are complete and accessible.

How to Check Compatibility of Plugins and Themes

Check the compatibility of plugins and themes by doing the following steps:

1. Review your active plugins and themes – Check each plugin’s documentation for compatibility with the PHP version you plan to use on your VPS. Some older plugins may not support PHP 8.x, requiring updates or replacements.
2. Deactivate caching and optimization plugins – Deactivate plugins (like WP Rocket, W3 Total Cache, or SG Optimizer) temporarily because they may cause conflicts during migration. They can be re-enabled after the move.

Setting Up Your VPS Environment

A) Choosing Between Linux and Windows Operating Systems

For WordPress hosting, Linux is the preferred operating system. WP runs natively on Linux, and most hosting documentation and community support assume a Linux environment. Ubuntu is the most used distribution due to its extensive community support, frequent security updates, and ease of use for beginners. Windows is rarely used for WordPress hosting unless your infrastructure specifically requires Windows-specific applications. For this migrate WordPress to VPS guide, we’ll assume a Linux Ubuntu distribution for the subsequent procedures in this article.

B) Factors to Consider in Choosing the Ideal Web Server Application

Choose the best web server application based on the following factors:

• Apache: The traditional choice, known for its flexibility and .htaccess support. However, it consumes more memory than alternatives.
• Nginx: Increasingly the standard for WordPress VPS hosting due to its event-driven architecture, which handles high traffic with significantly lower memory consumption. Nginx + PHP-FPM is a powerful combination for WordPress.
• LiteSpeed: A commercial alternative offering built-in caching and performance optimizations, often used with the LiteSpeed Cache plugin.

Note: For beginners, Nginx offers an excellent balance of performance and community support. We’ll use the LEMP stack (Linux, Nginx, MariaDB, PHP-FPM) in this guide.

C) Required Extensions You Have to Install

WordPress requires specific PHP extensions to function properly.

1. On Ubuntu, install the PHP extensions with the following commands:On Ubuntu, install the PHP extensions with the following commands:
   • sudo apt update
   • sudo apt install nginx mariadb-server php-fpm php-mysql php-cli php-curl php-xml php-mbstring php-zip php-gd php-intl php-soap unzip curl wget
2. Adjust PHP configuration settings in /etc/php/8.1/fpm/php.ini for optimal WordPress performance:
   • memory_limit = 256M
   • upload_max_filesize = 64M
   • post_max_size = 64M
   • max_execution_time = 300
3. Create a database and user for WordPress:
   • CREATE DATABASE wordpress_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
   • CREATE USER ‘wp_user’@’localhost’ IDENTIFIED BY ‘strong_password’;
   • GRANT ALL PRIVILEGES ON wordpress_db.* TO ‘wp_user’@’localhost’;
   • FLUSH PRIVILEGES; WordPress requires specific PHP extensions to function properly.

Migrate WordPress to VPS (Files and Database)

A) How to Transfer WordPress Files via SSH

SSH (SCP or rsync) is the superior method for file transfers. While FTP/SFTP works, server-to-server transfers via SSH are significantly faster, so you don’t have to download to your local machine and then upload again.

Use SCP (Secure Copy) to transfer files directly with the following steps:

1. On the new VPS, generate an SSH key and add it to the old server’s ~/.ssh/authorized_keys for password less authentication. Then copy the files:
   • scp -r user@old_server_ip:/path/to/wordpress /var/www/html/
2. For larger sites, rsync is recommended as it can resume interrupted transfers and synchronize only changed files.
3. Set the correct file permissions after the transfer:
   • chown -R www-data:www-data /var/www/html/
   • find /var/www/html/ -type d -exec chmod 755 {} \;
   • find /var/www/html/ -type f -exec chmod 644 {} \;

B) How to Export and Import the Database

Do the following steps:

1. Export the database from the old server:
   • mysqldump –add-drop-table -u old_db_user -p old_db_name > export.sql
2. Transfer the SQL file via SCP and import it on the new VPS:Transfer the SQL file via SCP and import it on the new VPS:
   • mysql -u wp_user -p wordpress_db < export.sql

C) How to Update wp-config.ph with New Database Credentials

1. Edit your wp-config.php file and update the database settings to match the new environment:
   • define(‘DB_NAME’, ‘wordpress_db’);
   • define(‘DB_USER’, ‘wp_user’);
   • define(‘DB_PASSWORD’, ‘your_strong_password’);
   • define(‘DB_HOST’, ‘localhost’);

Configuring Domain and DNS Settings

A) How to Point Your Domain to the VPS IP Address

At your domain registrar or DNS provider, create or modify “A records” to point to your VPS IP address:

• A Record for @ (root domain): Points to your VPS IP
• A Record for www: Also points to your VPS IP

B) How to Set Up DNS Records

Before switching the DNS, lower the TTL (Time to Live) on your DNS records to 300 seconds (5 minutes) at least 24 hours before cutover. This ensures that DNS changes propagate quickly. After verification, update the A records to your virtual private server IP. During this period, you can test your site locally by editing your computer’s hosts file to point your domain to the new VPS IP.

Optimizing WordPress on a Virtual Private Server

How to Optimize WordPress on VPS

With your WP site live on the virtual private server, do the following steps:

1. Install an SSL Certificate: Use Let’s Encrypt with Certbot:
   • sudo apt install certbot python3-certbot-nginx -y
   • sudo certbot –nginx -d yourdomain.com -d www.yourdomain.com
   • This step sets up automatic HTTPS and redirects HTTP to HTTPS.
2. Enable Caching: Install a caching plugin like WP Rocket or W3 Total Cache. On the server level, enable OPcache for PHP and consider Redis for object caching.
3. Optimize Images: Compress images using plugins like Imagify or ShortPixel.
4. Monitor Resources: Use the top or htop command to monitor CPU and memory usage. Adjust PHP memory limits or upgrade VPS resources if needed.

Testing and Troubleshooting

A) How to Check Site Functionality

Do the following steps:

1. Systematically test your site after migration with the following steps:
2. Browse the homepage and key pages.
3. Test contact forms, checkout processes, and search functionality.
4. Log in to the WordPress admin dashboard.
5. In the dashboard, verify images, CSS, and JavaScript load correctly (use browser Developer Tools > Network tab).
6. For the final cutover, consider a gray rollout: switch DNS for a small user group first, monitor, then expand to all traffic.

B) How to Fix Common Migration Errors

Do the following steps:

1. “Error Establishing a Database Connection”: Double-check database credentials in wp-config.php. Ensure that the database name, user, password, and host are correct.
2. HTTP 500 Error: Usually a PHP or plugin conflict. Deactivate all plugins via FTP (rename the wp-content/plugins folder), then reactivate one by one to identify the culprit.
3. Missing Images or Broken Layout: Update URLs in the database to reflect the new domain:
   • UPDATE wp_options SET option_value = REPLACE(option_value, ‘old_domain.com’, ‘new_domain.com’);
   • UPDATE wp_posts SET post_content = REPLACE(post_content, ‘old_domain.com’, ‘new_domain.com’);
4. Use WP-CLI for a safer alternative: wp search-replace ‘old_domain.com’ ‘new_domain.com’ –all-tables

C) How to Use Error Logs for Debugging

Error logs are invaluable for troubleshooting. Do the following steps:

1. Web server logs: /var/log/nginx/error.log or /var/log/apache2/error.log
2. PHP-FPM logs: /var/log/php8.1-fpm.log
3. WordPress debug: Enable debugging in wp-config.php with the following commands:
   • define(‘WP_DEBUG’, true);
   • define(‘WP_DEBUG_LOG’, true);
