any how-tos available on how to replace bbpress standalone with the plugin?

I am trying to replace my bbpress standalone (integrated with wp 3.2.1 multisite) with the plugin but am having all sorts of trouble. I managed to import the old stuff aka forums and topics then managed to use a shortcode inserted in a page to display the forums but they look all weird and the permalinks don't work anymore.
I reverted back to the standalone version for now but I'd really appreciate it if you guys could do a write-up on this, maybe for wpmu.org?
