Tell us what you are trying to do? Site was built using regular translation editor for Spanish because the advanced translator was not working great at that time. But now english page texts are getting updated. I want to use the advanced translation editor from now on. Also we are adding French. But don't want to lose any existing translations.
Is there any documentation that you are following? Yes but it is confusing. One doc said I would lose the translation upon changing to the advanced. The other doc said it would just switch back to the regular translator upon each use. Only new pages would allow use of the advanced translator. Neither of these options are acceptable.
As the settings page, itself says, "old translation may be unusable", I request you to follow the below steps to ensure the switch without content loss.
- Backup your site
- Open the page in classic translation editor and make sure it's 100% translated.
- Once the page is 100% translated, go to Settings->Multilingual content setup -> How to translate pages and post ->Content that was created using classic translation editor and choose switch to use advanced translation editor.
