How to Migrate a WordPress Site from Localhost to Live: Developer Guide

ByBrian Bateman

Migrating a WordPress site from a local development environment to a live production server is a crucial skill for developers, web designers, and digital agencies. This process ensures that your carefully crafted site is seamlessly accessible by the world, maintains data integrity, and delivers peak performance. A robust, error-free migration safeguards against downtime, broken links, and data loss—pitfalls that can impact user experience and business continuity. The following comprehensive guide outlines each step of the migration journey, focusing on technical nuances, practical strategies, and tools that streamline and future-proof the process.

Understanding the Migration Process

Migrating a WordPress site is more than copying files. WordPress’s dynamic architecture—its reliance on a MySQL database, PHP files, and interdependent configuration—means site data, settings, media uploads, and URLs must be carefully synchronized between local and live environments. A systematic approach minimizes risks like downtime, broken links, and security vulnerabilities. Developers must also understand the impact of serialized data, environment-specific variables, and server configurations on the migrated site’s integrity.

Preparing Your Local WordPress Environment

Prior to migration, ensure your local site is in final production-ready form. This means:

  • Removing unused themes, plugins, or test data.
  • Optimizing assets (images, scripts, styles).
  • Ensuring all content and configurations are up-to-date.
  • Running a local backup with tools like Duplicator or UpdraftPlus.
    Consider using WP_DEBUG mode to identify and fix errors before moving to live. This proactive prepping avoids porting nonessential data and increases migration predictability.

Choosing the Right Hosting and Live Server

Select hosting that matches your project’s technical requirements and growth expectations. Compare features such as:

  • PHP/MySQL versions and compatibility
  • SSL support
  • SSH/FTP access
  • Performance (e.g., SSD storage, CDN integration)
    Evaluate if managed WordPress hosting (e.g., Kinsta, SiteGround) suits your hands-off approach or if VPS/dedicated solutions give you granular control. Ensure your live server’s environment closely mirrors your local setup to reduce platform-specific issues post-migration.

Backing Up Your Site Data and Files

Before any migration step, back up both your database and files. Use plugins like BackupBuddy or manual methods (phpMyAdmin for databases, direct file copy for wp-content and site root). Store backups in multiple locations—local, remote cloud, or external drives. Verify backup completeness with checksum validation. This backup forms your safety net against data loss or rollbacks.

Exporting the WordPress Database

To move your database, export it from your local server. Use phpMyAdmin, command-line tools (mysqldump), or migration plugins. Ensure export settings include all tables, structure, and data. For large databases, enable compression (SQL GZIP) to reduce file size. Double-check to exclude autogenerated tables from local-specific plugins that won’t be installed live.

Configuring wp-config.php and Environment Settings

Update your wp-config.php to reflect the live server’s credentials and paths:

  • Edit DB_NAME, DB_USER, DB_PASSWORD, DB_HOST to match live MySQL settings.
  • Set WordPress and site URLs (WP_HOME, WP_SITEURL) for the live domain.
  • Check for hardcoded local paths or absolute URLs and adjust as needed.
  • Consider defining environment-specific variables for debugging or caching, and ensure file permissions are optimized for security.

Importing the Database to the Live Server

Upload your exported database to the live MySQL server using phpMyAdmin, CLI (mysql), or host-specific management tools. Confirm that:

  • The database is freshly created and empty, avoiding data conflicts.
  • Table prefixes in the import match those configured in wp-config.php.
  • Import completes without errors or warnings—review logs for issues with large files or timeouts, and increase server limits if needed.

Uploading Site Files via FTP or SSH

Transfer all site files—core WordPress folders, wp-content, themes, plugins, and uploads—using FTP clients (e.g., FileZilla) or, ideally, secure and faster SSH/SFTP methods. Maintain the original folder structure and set correct file permissions (typically 755 for directories, 644 for files). Exclude temporary caches or local configuration files not needed live.

Updating URLs and Handling Serialized Data

After migration, internal links and serialized settings may still point to your local environment. Tools like WP-CLI’s search-replace or plugins (e.g., Better Search Replace, WP Migrate DB) update URLs while managing serialization integrity. Run wp search-replace 'http://localhost' 'https://yourlivesite.com' --all-tables via WP-CLI as an example. Always backup before such operations, and validate key paths in both Settings and database.

Managing Permalinks and .htaccess Adjustments

Permalinks often break during migration due to .htaccess differences or server rewrites.

  • Go to Settings > Permalinks and resave your desired structure.
  • Replace or edit .htaccess to reflect your live server’s rewrite rules (e.g., add mod_rewrite if moving from Windows to Linux).
  • For NGINX, adjust rewrite rules in your server block/config files accordingly.
    These steps are vital for SEO and avoidance of 404 errors.

Testing and Troubleshooting Post-Migration

Extensively test your live site:

  • Check all front-end pages, forms, logins, and media.
  • Test plugin and theme functionality.
  • Review error logs for database, PHP, or permission issues.
  • Use developer tools to inspect network requests and performance.
    Clear all caches after changes. If issues arise, restore from backups or work stepwise to isolate root causes (plugin conflicts, missing files, incorrect database options).

Implementing Security Best Practices

Harden your now-public site:

  • Enforce SSL/HTTPS throughout.
  • Change all critical credentials and database passwords used locally.
  • Remove unused themes/plugins, and set correct file permissions.
  • Install a comprehensive security plugin (Wordfence, Sucuri).
  • Restrict wp-admin access with .htaccess or IP whitelisting.
    Routinely scan your site and automate backups going forward.

Tools and Plugins to Streamline Migration

A variety of plugins and command-line tools reduce manual effort:

  • All-in-One WP Migration and Duplicator automate backup, export, and import.
  • WP Migrate DB Pro allows granular, safe DB migration with serialized data handling.
  • WP-CLI enables fast search/replace, user management, cache purging, and more for sysadmins.
  • Hosting control panels may also offer built-in migration wizards for faster transitions.

Post-Launch Checklist for Quality Assurance

After the migration is live, execute a final checklist:

  • Validate all URLs, media, widgets, menus, and forms.
  • Verify SEO essentials: sitemaps, robots.txt, canonical tags.
  • Check Google Analytics and Search Console integration.
  • Conduct mobile- and cross-browser testing.
  • Confirm backup and security schedule is active.

Long-Term Maintenance and Scalability Considerations

Migration isn’t the finish line. Plan for ongoing updates, scaling, and security:

  • Regularly update core, themes, and plugins.
  • Monitor resource usage—consider auto-scaling, advanced caching or CDN if traffic grows.
  • Document your migration process for team knowledge transfer.
  • Periodically test backups, recovery plans, and disaster recovery workflows.
    This foundation makes future site upgrades or hosting changes far less risky.

FAQ

Is it possible to migrate a WordPress site without plugins?
Yes. Manual migration using phpMyAdmin, FTP/SFTP, and command-line tools is entirely feasible and gives greater control.

How do I fix broken images after migration?
Most issues arise from incorrect uploads path or URLs. Check wp-content/uploads permissions and use a search-replace tool to update media URLs if necessary.

What if my site is too large for phpMyAdmin imports?
Use command-line mysql, split the SQL file, or ask your host for increased upload limits. Tools like Duplicator also help bypass import size limits.

Does moving a site affect SEO or Google rankings?
If URLs, redirect rules, and canonical links are preserved, and no downtime occurs, SEO impact is minimal. Always resubmit your sitemap via Google Search Console post-migration.

How do I handle SSL when going live?
Set up SSL certificates before launch (Let’s Encrypt or commercial CA), force HTTPS via .htaccess or WP plugins, and update all settings/URLs to use https://.
