Question [Q] How to upgrade ROMs for HTC

I am currently running the Bad Boy ROM v1.3. I want to upgrade to their latest ROM but im not sure how to go through the upgrade process. Do I need to do a backup move it to my computer then run a RUU for 4.3 then do the carrier upgrade then reflash recovery and then flash the new ROM? I could not seem to find an answer. Any guidance would be appreciated.
