Is there a checklist outlining what we should do when our URL rewrites include the forum title and we want to rename a forum, yet 301 redirect any old links to the new URL?

My current rewrites look like:

[forum_title]/
[forum_title]/index[forum_page].html
[forum_title]/announcement-[announcement_title].html
[forum_title]/announcements.html
[forum_title]/poll-[poll_id]-[poll_title].html
[forum_title]/[thread_title]-[thread_id].html

I assume everything with a poll_id or tread_id will redirect automatically and I will need to create custom redirects for the rest.

Will the announcement_title posts redirect automatically?
