I last played shortly before 2.3 and have 100+ mods installed. Do I need to update each and every one?

As title says, my last game was pre 2.3 and it has tons of mods, enough that I would really hate to have to redownload and reinstall each and every one. I’m hoping the 2.3 update was perhaps minor enough that I would only need to reinstall specific key dependency mods. Does anyone know if this is the case? Or will I need to do a full reinstall?
