Before You Begin

1. Backup Your Database

mysql export phpmyadmin

Before making any changes to your database, it’s crucial to create a full backup:

  1. Log in to your hosting control panel
  2. Access phpMyAdmin
  3. Select your WordPress database
  4. Click on the “Export” tab
  5. Choose “Quick” export method and “SQL” format
  6. Click “Go” to download the backup file

2. Gather Necessary Information

You’ll need:

  • Your database table prefix
  • Your old domain URL
  • Your new domain URL

Step-by-Step Guide

  1. Find Your Database Table Prefix
    • Open your WordPress wp-config.php file
    • Look for a line like: $table_prefix = 'wp_';
    • The value (e.g., ‘wp_’) is your table prefix
  2. Access the WP Update URL Tool
    • Navigate to the tool on your website
  3. Fill in the Form
    • Enter your database table prefix (e.g., wp_)
    • Enter your old domain URL (e.g., https://oldsite.com)
    • Enter your new domain URL (e.g., https://newsite.com)
  4. Generate MySQL Queries
    • Click the “Generate Snippet” button
    • The tool will display the necessary MySQL queries
  5. Copy the Generated Queries
  6. Execute the Queries (covered in the Using the Generated MySQL Queries section)

Understanding Database Table Prefix

The database table prefix is a string of characters prepended to your WordPress database table names. It’s used to:

  1. Differentiate between multiple WordPress installations in a single database
  2. Enhance security by making table names less predictable

Common prefixes include:

  • wp_ (default)
  • wp23_
  • mysite_

SSL and HTTPS Considerations

When migrating your site, consider whether you’re moving from HTTP to HTTPS or vice versa:

  • HTTP to HTTPS: Ensure your new domain has an SSL certificate installed
  • HTTPS to HTTP: Be aware this may cause security warnings in browsers

Examples:

  • http://oldsite.com to https://newsite.com
  • https://oldsite.com to https://newsite.com

Always use HTTPS when possible for better security.

Using the Generated MySQL Queries

After generating the queries:

  1. Access Your Database
    • Log in to phpMyAdmin through your hosting control panel
  2. Select Your WordPress Database
  3. Open SQL Query Interface
    • Click on the “SQL” tab
  4. Paste and Execute Queries
    • Paste the generated queries into the SQL query box
    • Click “Go” to execute

Example queries:

UPDATE wp_options SET option_value = replace(option_value, 'https://oldURL.com', 'https://newURL.com') WHERE option_name = 'home' OR option_name = 'siteurl';
UPDATE wp_posts SET guid = replace(guid, 'https://oldURL.com', 'https://newURL.com');
UPDATE wp_posts SET post_content = replace(post_content, 'https://oldURL.com', 'https://newURL.com');
UPDATE wp_postmeta SET meta_value = replace(meta_value, 'https://oldURL.com', 'https://newURL.com');
UPDATE wp_links SET link_url = replace(link_url, 'https://oldURL.com', 'https://newURL.com');
UPDATE wp_comments SET comment_author_url = replace(comment_author_url, 'https://oldURL.com', 'https://newURL.com');

Troubleshooting

If you encounter issues:

  1. Check Your Table Prefix: Ensure you’ve entered the correct prefix in the tool
  2. Verify URLs: Double-check both old and new URLs for typos
  3. Database Permissions: Make sure your database user has UPDATE privileges
  4. Restore Backup: If something goes wrong, restore your database from the backup you created

Remember, always test thoroughly after making these changes to ensure your WordPress site functions correctly with the new domain.
