Renaming a forum : no redirection possible ?

[Jnifoo]

Hi, using vbseo for a while now, and after a huge reorganization of our forums, we have decided to enhance the relevancy of the keywords used on some of our forums (containing subforums).
Unfortunately, after a simple test, renaming one primary forum (french language) "social et travail" to "droit du travail", the new url converted by vbseo become "/forum/droit-travail/".

But how can I tell vbseo or vbulletin to redirect with a 301, the old URL '/forum/social-travail/' to the new one '/forum/droit-travail/' ?
I test with "Define Custom 301 Redirects", but anyway, when I go to the old URL, vbulletin display this error "Invalid Forum specified. If you followed a valid link, please notify the administrator"
... And actually, I could test any unknown url of the type '/forum/anyword/' and the same error message appear under vbulletin.

Any solution to help me figure it out ?
Thanks for your help.

Hello,

you can add this to the "Custom Redirect" option in vBSEO CP:

'social-travail/(.*)' => 'droit-travail/$1'
