Reply To: Translation of default theme text, then to another language: Loco + WPML?

OK. So I need to start with Loco Translate, localize the English theme strings into Dutch, then use WPML to translate from Dutch to English, correct?

Do I need to remove Loco after I finished translating (before I use WPML)?

Please could you also include info on how to make sure translations are not deleted during updates? I am using a child theme already.
