cherche code 301 redirection htaccess valable pour sauver mon site

Bonjour,
voila  j'avais un site ( forum xenforo) se trouve à www.domain.com 'root . Je l'ai mis sur   domain.com/community et placer WordPress à la racine.
pour avoir blog + un forum, le trandfere des dossiers c'est bien passer tout marche bien sauf mais encien liens ou URL reference par google et autres j'ai errrur 404

Je veux installer une redirection afin que toute personne visitant domain.com/threads/successful-upgrade-minor-problem.52851/ (permet de dire que ceci est un exemple d'une recherche Google) pourrait être redirigé vers les nouveaux domain.com / communauté / fils /successful-upgrade-minor-problem.52851/ URL. Donc , les gens qui viennent de Google ne trébucheront pas simplement sur un lien mort.

En même temps, si un visiteur visite domain.com directement, il serait de voir WordPress.

je n'arrive pas a faire une redirection 301,  malgré mes recherche sur le net. surtout que j'ai deux fichiers htaccess Aidez-moi, s'il vous plaît

jai deux fichier .htaccess

1- sur la racine celui du worpdress
