Problem: The client is attempting to update an older version of WPML (4.3.15) on a large WooCommerce site and is concerned about potential issues such as site crashes during the update process. They are also inquiring about the best approach to update WPML and its related add-ons like WooCommerce Multilingual, WPML String Translation, and WPML Translation Management.
Solution: We recommend a gradual update process to minimize risks: 1. Temporarily deactivate all WPML add-ons. 2. Deactivate and delete the main WPML plugin. 3. Gradually update WPML by downloading and installing intermediate versions in this order: 4.3.15, 4.4.7, 4.5.0, 4.6.0, and finally 4.7.3. You can find these versions in the WPML changelog at WPML Changelog. 4. Once updated to WPML 4.7.3, delete the outdated add-ons and download the necessary ones from the Plugins->Add new->Commercial tab. 5. Note that WPML Translation Management is no longer required and won't be available for download.
If you encounter issues or this solution does not apply due to updates or specific circumstances, please check related known issues at WPML Known Issues, verify the version of the permanent fix, and ensure you have installed the latest versions of themes and plugins. If problems persist, we highly recommend opening a new support ticket at WPML Support Forum for further assistance.
