Migrating from Shared Hosting to VPS - Complete Guide (2025)

Migrate your website from shared hosting to VPS. Complete guide covering backup, DNS, data transfer, and optimization with minimal downtime.

Your website has outgrown shared hosting. You're experiencing slow load times, resource limits, and restrictions that hold your project back. It's time to migrate to a VPS (Virtual Private Server) - but the thought of migrating feels overwhelming.

Don't worry. In this comprehensive guide, I'll walk you through the entire migration process step-by-step, from preparation to post-migration optimization. By the end, you'll have successfully moved your site with minimal downtime.

Why Migrate from Shared Hosting to VPS?

Before diving into the migration process, let's understand why VPS hosting is superior to shared hosting:

Migration Timeline: Plan for 2-4 hours of total work, spread across 2-3 days to account for DNS propagation. Active downtime can be as little as 5-10 minutes with proper planning.

Phase 1: Pre-Migration Preparation (Critical Step)

Proper preparation is the difference between a smooth migration and a disaster. Follow this checklist:

1. Create Complete Backups

Never trust your hosting provider's backups alone. Create your own:

# From your cPanel or shared hosting panel:
1. Backup all files (File Manager → Compress → Download)
2. Export all databases (phpMyAdmin → Export → SQL format)
3. Save email accounts/forwarders configuration
4. Screenshot DNS records
5. Export any cron jobs
Critical: Store backups locally AND in cloud storage (Google Drive, Dropbox). Hard drive failures happen during migrations more often than you'd think.

2. Document Your Current Setup

You need to know exactly what you're migrating:

3. Choose Your VPS Provider

Popular reliable options:

4. Set Up Your VPS

Minimum recommended specs for a typical website:

Phase 2: Setting Up Your VPS Environment

1. Initial Server Setup (Security First)

After creating your VPS, immediately secure it:

# SSH into your server
ssh root@your-server-ip

# Update system packages
apt update && apt upgrade -y

# Create a non-root user
adduser yourusername
usermod -aG sudo yourusername

# Set up firewall
ufw allow OpenSSH
ufw allow 'Nginx Full'  # or 'Apache Full' if using Apache
ufw enable

# Disable root login (after confirming sudo user works)
nano /etc/ssh/sshd_config
# Set: PermitRootLogin no
systemctl restart sshd

2. Install Web Server Stack (LEMP/LAMP)

For most sites, LEMP (Linux, Nginx, MySQL, PHP) is recommended:

# Install Nginx
apt install nginx -y

# Install MySQL
apt install mysql-server -y
mysql_secure_installation

# Install PHP and common extensions
apt install php8.3-fpm php8.3-mysql php8.3-curl php8.3-gd \
php8.3-mbstring php8.3-xml php8.3-zip php8.3-bcmath -y

# Verify installations
nginx -v
mysql --version
php -v
Alternative: If you prefer a control panel like cPanel, consider using free alternatives like Webmin, VestaCP, or CyberPanel. However, learning the command line gives you more control and better troubleshooting skills.

3. Configure Your Web Server

Create an Nginx server block for your domain:

# Create server block file
nano /etc/nginx/sites-available/yourdomain.com

Basic configuration:

server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;
    root /var/www/yourdomain.com;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php8.3-fpm.sock;
    }
}

# Enable the site
ln -s /etc/nginx/sites-available/yourdomain.com /etc/nginx/sites-enabled/
nginx -t  # Test configuration
systemctl reload nginx

Phase 3: Data Migration

1. Transfer Files

Multiple methods, choose based on your file size:

Method A: Direct Transfer (for smaller sites, <1GB)

# From your local machine where you have the backup
scp -r /path/to/website-files yourusername@your-vps-ip:/var/www/yourdomain.com

Method B: Using rsync (for larger sites, faster)

# If your old host allows SSH access
rsync -avz -e ssh /home/username/public_html/ yourusername@your-vps-ip:/var/www/yourdomain.com/

Method C: FTP to VPS (if no SSH on old host)

# Install FTP server on VPS
apt install vsftpd -y
# Configure vsftpd, then use FileZilla to upload files

2. Migrate Databases

# On your VPS, create the database
mysql -u root -p
CREATE DATABASE your_database_name;
CREATE USER 'your_db_user'@'localhost' IDENTIFIED BY 'strong_password';
GRANT ALL PRIVILEGES ON your_database_name.* TO 'your_db_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

# Import your database backup
mysql -u root -p your_database_name < /path/to/database-backup.sql

3. Update Configuration Files

For WordPress sites:

# Edit wp-config.php
nano /var/www/yourdomain.com/wp-config.php

# Update these lines:
define('DB_NAME', 'your_database_name');
define('DB_USER', 'your_db_user');
define('DB_PASSWORD', 'strong_password');
define('DB_HOST', 'localhost');

4. Set Correct Permissions

# Set ownership
chown -R www-data:www-data /var/www/yourdomain.com

# Set secure permissions
find /var/www/yourdomain.com -type d -exec chmod 755 {} \;
find /var/www/yourdomain.com -type f -exec chmod 644 {} \;

Phase 4: DNS Migration (The Zero-Downtime Trick)

This is where you minimize downtime to just a few minutes:

Strategy: Lower TTL Before Migration

48 hours before migration:
1. Log into your domain registrar/DNS manager
2. Find your DNS records' TTL (Time To Live)
3. Lower TTL to 300 seconds (5 minutes)
4. Wait 48 hours before proceeding
Why this works: DNS records are cached globally based on TTL. By lowering it to 5 minutes before migration, when you switch to your VPS IP, the change propagates in minutes instead of hours or days.

Switch DNS Records

1. Test your site on the VPS by editing your local hosts file first
   # Linux/Mac: /etc/hosts
   # Windows: C:\Windows\System32\drivers\etc\hosts
   your-vps-ip yourdomain.com

2. Once confirmed working, update your A record:
   - Log into DNS manager
   - Change A record from old hosting IP to VPS IP
   - Update www CNAME if needed

3. Wait 5-15 minutes and test from different devices/networks

Phase 5: Post-Migration Checklist

1. Install SSL Certificate

# Using Let's Encrypt (free)
apt install certbot python3-certbot-nginx -y
certbot --nginx -d yourdomain.com -d www.yourdomain.com

# Auto-renewal is configured automatically
certbot renew --dry-run  # Test renewal

2. Set Up Email (If Applicable)

Options:

3. Configure Backups on VPS

# Simple backup script
nano /root/backup.sh
#!/bin/bash
BACKUP_DIR="/root/backups"
DATE=$(date +%Y-%m-%d)

# Backup files
tar -czf $BACKUP_DIR/files-$DATE.tar.gz /var/www/yourdomain.com

# Backup database
mysqldump -u root -p'yourpassword' your_database_name > $BACKUP_DIR/db-$DATE.sql

# Delete backups older than 7 days
find $BACKUP_DIR -type f -mtime +7 -delete

chmod +x /root/backup.sh

# Add to cron (daily at 2 AM)
crontab -e
0 2 * * * /root/backup.sh

4. Set Up Monitoring

Common Migration Issues and Solutions

Issue 1: "Database Connection Error"

Solution: Verify database credentials in config file and ensure MySQL is running:

systemctl status mysql

Issue 2: "403 Forbidden" Error

Solution: File permissions issue:

chown -R www-data:www-data /var/www/yourdomain.com

Issue 3: Site Loads But Looks Broken (No CSS)

Solution: Update site URL in database (WordPress example):

mysql -u root -p your_database_name
UPDATE wp_options SET option_value='https://yourdomain.com' WHERE option_name='siteurl';
UPDATE wp_options SET option_value='https://yourdomain.com' WHERE option_name='home';

gzip on;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml;
gzip_min_length 1000;

3. Set Up a CDN

Conclusion

Migrating from shared hosting to a VPS is a significant upgrade that gives you better performance, more control, and room to grow. While the process requires careful planning, following this guide systematically will result in a smooth transition with minimal downtime.

The key is preparation: create backups, lower your DNS TTL early, test thoroughly on the VPS before switching DNS, and keep your old hosting active for a month as a safety net.

Pro Tip: Document every step of your migration. Create a private document with all your commands, configurations, and troubleshooting steps. This will be invaluable for future updates or if you need to migrate again.
