Readme github.com/ardijancuri/wordpress-importer ↗

Export and import a complete single-site WordPress install with database, uploads, themes, plugins, languages, and selected root files.

Description

WP Site Migrator creates a downloadable migration package on the source site and imports that package on a destination site. It is designed for single-site WordPress migrations, including local-to-live moves.

For larger sites up to 2 GB, the plugin exports one standard ZIP package that contains the manifest, database, and files. Older multipart exports are still accepted on import for compatibility.

This version intentionally focuses on package-based migrations. It does not support multisite, direct server-to-server push, retained destination backups, or WordPress core replacement.

Migration Scope

The export package includes:

  • Database tables using the current WordPress table prefix, including custom plugin tables.
  • Uploads, themes, plugins, mu-plugins, and languages.
  • Selected root files: .htaccess, web.config, robots.txt, and favicon.ico.

The package excludes WordPress core, wp-config.php, database credentials, salts, migration packages, and transient upload cache/log/backup folders.

Security

Only administrators with manage_options can use the plugin. REST requests require WordPress REST nonces. Migration packages are stored in randomized protected folders under wp-content, and imports validate checksums before replacing data.

Installation

  1. Upload the wp-site-migrator folder to /wp-content/plugins/.
  2. Activate the plugin in WordPress admin.
  3. Go to Tools > Site Migrator.
