WPML to Polylang

Features

• Imports languages and WPML options (when the same options exist in Polylang).
• Imports posts and terms languages as well as translations (including for custom post types and custom taxonomies).
• Imports multilingual nav menus.
• Imports strings translations.
• Does not delete WPML data.

Important

Although WPML data should not be corrupted, as Polylang data are created without deleting anything, make a database backup before proceeding.

How to proceed?

• De-activate WPML
• Activate Polylang or Polylang Pro and WPML to Polylang. Do not create any language with Polylang (they will be imported).
• Go to Tools -> WPML Importer.
• If all checks are passed, then you can click on ‘Import’.
• De-activate WPML to Polylang (You can even delete it).
• Setup a language switcher either as a widget or in nav menus.
• Check that everything is OK.
• If something went wrong and you want to revert to WPML, you can delete Polylang using the red link in the Plugins table. To delete all data created for Polylang, Please read how before deleting Polylang. Finally you can re-activate WPML.

Notes

This plugin does not include error management. It has however been tested successfully to migrate a site with about 9,000 posts and media.
