Upgrading urls / replacement text

[محروم.كوم]

Hello.
Recently, I transfer my old forum PNphpBB2 to VB.
I view that I have 2 differents problems with some url's.

In my old forum (PNphpBB2) the url's are in format .html, for example:

Code:
http://www.myforum.com/PNphpBB2-viewtopic-t-3911.html
or
http://www.myforum.com/PNphpBB2-view...ight-axel.html
I execute cleaner.php but not upgrade any url (I don't made any change in cleaner.php).

My second "problem" with url's are, my old forum are based in web (postnuke with PNphpBB2) for this reason, some urls in my forum called a modules of web, for example:
Code:
www.myforum.com/CmodsDownloads.html or www.myforum.com/dpDocs.html
it's possible changed this url for new urls that call to my new main forum?

Thanks and a regards. __DEFINE_LIKE_SHARE__
