Domain Replacer WordPress Plugin is a robust and intelligently designed tool created for WordPress administrators, developers, and site migration experts. Whether you're moving to a new domain, updating URLs after switching to HTTPS, or cleaning up legacy data, this plugin provides a safe and efficient way to replace domains across your entire WordPress website.

Packed with advanced features like dry-run mode, protocol preservation, AJAX-based background processing, and progress indicators, the plugin ensures accurate domain replacement without database corruption or downtime.

Key Features:

🔄 Safe Domain Replacement

Replace old domains with new ones across posts, pages, custom post types, custom fields, serialized arrays, and the WordPress options table—all handled safely to prevent data corruption.

🧪 Dry Run Mode

Test changes without modifying your database. Dry Run scans and reports what will be replaced, giving you full confidence before executing the final replacement.

⚙️ Custom Field & Options Table Support

Automatically processes postmeta fields and the WordPress options table, ensuring complete domain coverage.

🔗 Protocol Preservation

Choose whether to preserve the original http or https protocol during replacements—perfect for complex migrations.

📝 Detailed Logging

Every replacement and action is logged to a file so you can review exactly what changed, when, and where.

💻 WP-CLI Support

Run domain replacements directly from the command line—ideal for developers and automated workflows.

# Dry run (test only)
wp domainreplace --dry-run

# Full replacement

Replacement tasks run in the background without freezing your screen, making the plugin responsive even for large websites.
