XF 2.2 Redirect old vBulletin URL using DBSEO to new xenforo install

[OlijO]

Hi, we migrate our old vBulletin 4.2 to xenforo. We would like to not loosing our seo referal so we would like to redirect old url to new one. Old one has this structure : Forum name :
forum.oursite.com/forum-name/
Thread inside a forum :
forum.oursite.com/forum-name/digit-thread-name.html
Multipage thread inside a forum :
forum.oursite.com/forum-name/digit-thread-name-digit.html
We want to redirect this old structure to new one to have : Forum name :
forum.oursite.com/forum-name/
Thread inside a forum :
forum.oursite.com/forum-name/digit-thread-name
Multipage thread inside a forum :
forum.oursite.com/forum-name/digit-thread-name-digit
Previous vbulletin install used DBSEO to work so i suppose this is the reason the redirect seems to not working as explained in the documentation there :

Import notes: vBulletin | Manual | XenForo

End-user documentation for XenForo

xenforo.com

We tried also with the addons from DragonBytes : https://xenforo.com/community/resources/dbtech-dragonbyte-seo-urls-to-xenforo-2.6361/
but it doesn't work too.
Any help ?
Thanks !
