I’ve looked everywhere I can imagine for this but can’t seem to find a solid answer. Will the MCC insider XP be migrated over to the live version of MCC? Is this something anyone is actually interested in besides me? Would love to hear from other players or 343.
No, nothing transfers from Insider builds over to retail
Thank you for the quick reply! 
That was my assumption but wasn’t sure. Feel free to close the thread now that we have an answer.
