[Risolto] Setting up the best process to translate an existing site

Background of the issue:
We will be translating the site link nascosto from English to Japanese and Spanish. Your documentation suggests creating a development site, making the translations on the development site, and then publishing those translations to the public site. We would like to use a different process since the translations will happen in stages over months. We would like to install WPML on the public site and publish translated content in stages from within the public site's WPML plugin once translations are approved.

Symptoms:
Uncertainty about the process of moving translations from a development site to a public site and whether WPML can handle staged translations directly on the public site.

Questions:
Instead, we would like to use a different process since the translations will happen in stages over months. We would like to install WPML on the public site, and publish translated content in stages from within the public site's WPML plugin once translation are approved. I'm assuming that any translated content would be shown under the "flag" of the chosen language, and that untranslated content would simply show up only in English. Not ideal, but we are willing to live with it. Do you foresee a basic problem with this alternative approach?
