The answer to this question seems to be described in detail in this Shopify documentation:"Publishing themes" https://help.shopify.com/manual/using-themes/publish-themes.
Please, let me know if this is not the case.
Thanks Arthur, I've seen that doc, but for me, it's not clear if the new theme will be live or not? I don't want the new theme to be live at this time, I just want it to be the current theme because when editing, Shopify always direct me to the current theme. Hope I'm clear...and sorry for my bad English which is not my first language.
