Migrating Your Website to a Kazepute VPS

Pre-Migration Checklist

Step 1: Prepare the New Server

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

# Install required software
sudo apt install -y nginx php8.3-fpm php8.3-mysql php8.3-mbstring \
  php8.3-xml php8.3-curl php8.3-zip php8.3-gd mariadb-server

# Secure MariaDB
sudo mysql_secure_installation

Step 2: Migrate the Database

On the old server:

mysqldump -u root -p --all-databases --single-transaction > all_databases.sql
gzip all_databases.sql
scp all_databases.sql.gz deploy@new-server-ip:~/

On the new server:

gunzip all_databases.sql.gz
sudo mysql < all_databases.sql

Step 3: Migrate Files

# From old server — sync web files
rsync -avz --progress -e ssh /var/www/html/ deploy@new-server-ip:/var/www/html/

# Sync configuration
rsync -avz /etc/nginx/sites-available/ deploy@new-server-ip:~/nginx-configs/

Step 4: Configure Web Server

# Copy Nginx configs
sudo cp ~/nginx-configs/* /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/mysite.conf /etc/nginx/sites-enabled/

# Test and reload
sudo nginx -t && sudo systemctl reload nginx

Step 5: SSL Certificates

# Install certbot
sudo apt install -y certbot python3-certbot-nginx

# Get new certificates (after DNS points to new server)
sudo certbot --nginx -d example.com -d www.example.com

Step 6: Switch DNS

Update your A record to point to the new server IP. With TTL lowered to 300 seconds, propagation is fast.

# Verify DNS is pointing to new server
dig +short example.com

Step 7: Post-Migration Verification

Rollback Plan

Keep the old server running for at least 7 days after migration. If anything goes wrong:

1. Point DNS back to old server
2. Investigate and fix the issue on the new server
3. Re-attempt migration

Tip Do the DNS switch during your lowest-traffic hours. Monitor the new server closely for the first 24 hours.
