Moving all CSS customizations from “Quick CSS” to “style.css” file

Hi folks.
SInce the beginning of my work with Enfold, I’ve added all my CSS customizations to the “quick CSS” frame in the Theme options.
Can I safely cut & paste all those customizations to the “style.css” file, in the Theme file editor?
(The style.css on the “Enfold CHILD”, of course.)

I’ve already made a test with the staging website and, after a quick test, it seems I had no side effects.
Can you confirm I should not have any? Otherwise, I need to do a more detailed test in staging before doing it in production…

Side note: I have WPML (3 languages in total), and I’ve always kept the 3 different “quick CSS” aligned: there are no differences among the 3.
Another reason why I’d like to unify the CSS into the style.css file.

Thanks for your help!
Bye,
A.-
