Problem: The client is concerned about whether unregistering and re-registering a new WPML license will delete all of the old WPML data from their site. Solution: We assure you that unregistering and re-registering your WPML license will not delete any translations from your site. As a general precaution, we recommend always having a backup of your site. You should not notice any change in your site before or after registering a new site key. Once you register the new key, you can update WPML just as you normally did before.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If further assistance is needed, please open a new support ticket at WPML support forum.
