[consulting] "Forced" path redirect?

[Audrius Naslenas]

Hi,
 
Need advice from "path" magician :)
 
On the old site had content url path system wich is different from new one.
Now found, that there are some valuable backlinks to the old and obsolete
urls. Thought this is simple - install Path Redirect module and everything
is solved, but: some of those old links have pretty similar structure to
currently used views, and produce real (useless) pages when trying to access
them. When I try to add path redirect - getting "You cannot create a
redirect from a currently valid path." error.
 
Is there a way to do some kind of "forced" redirect? In Drupal 6 way
preferably...
 
Thank you.
