Maybe I can do something like moving the main site to a subdir, then bring the /test/ website as primary site ?

Otherwise I’m considering doing a staging website, how would you do that ? I can re-developpe my /test/ site as a staging website and then switching with the main one, but does that work once the multisite mode of wordpress is activated ?

thank you for your answer.

I’m not sure that this will do the trick. I mean, if I make the /test/ website point to the primary domain, what happened of the website that was already here ?

Here some screens of the DB that I’m supposed to change :
