Well , this will require one or two file edits
in file 'includes/vb5/frontend/routing.php'
line 239 just before throwing

PHP Code:

throw new vB5_Exception_404("invalid_page_url"); 


I have made some work
I used $path variable , exploded it and got the last element .. then queried node table for urlident equal to this value .
if true .. this returns node id
Then

PHP Code:

$url = vB_Api::instanceInternal('route')->getAbsoluteNodeUrl($id); 
header('Location: ' . $url, true, 301);
exit; 


I did this for a client who converted from smf with pretty URLs and working fine
I will post the full code when I have access to my home PC tomorrow.
Note : if the URL doesn't end with '/' you have to do additional work in includes\api\interface\collapsed.php'
