Quessing this is a follow up question from the last one: basically some weaopons and money can be kept to make it easier, but i dont think you can continue the story from hr6 if thats what your asking. Similar to the above answer: Like converting data from MHF1 to MHF2, I would assume that you keep all items, weapons, and armor that are 3 rarity or lower. Items rarer than that are converted into "ticket" to be redeemed once you reach a higher rank. You also lose your hunter rank, but keep your monster stats (sizes, number killed, etc). There are a few other loses, like your feylines.
