I dealt with some of these issues about a year ago. I was migrating from SMF 2* to bbPress and I had tons of issues with formatting in posts and missing data. I ended up hiring Michael Z Noble (http://wwww.michaelznoble.com/ – The 4 w’s is intentional 😉 ) to write a custom migration script to help me through all of these issues (as well as transfer a bunch of data like signatures, up/down votes, thread view counts, avatars, etc, into various bbPress/BuddyPress plugins/functions). The utf8mb4/utf8mb4_unicode_ci/character set issues were particularly tough for me to get through. I ended up switching to a new host that had a newer version of MySQL in order to successfully complete the migration. In short, if you aren’t a senior dev, hire a dev. 😉

Best of luck my friend! 🙂
