Thanks to guides like this I am feeling pretty good about things going smoothly. My concern is URL redirects after the conversion. I'm not too picky about keeping the same URL structure since this site doesn't get a ton of traffic right now but I do want to ensure that if the structure has to change, all of my old links are redirected properly. Specifically, I want to ensure they are 301 redirected properly.
How have others who have converted IPB handled this problem?
