JPM Private Banking

Hello All - I just got done with a summer internship at JPM's private banking group and have a return offer for an analyst that i am considering. JPM is a great firm, but  I have developed an increasing interest to start in IB. I am wondering what kind of exit options exist (in case I do not like my PB analyst experience after a year or two) - possible movement within JPM? Non-PB options outside JPM?

Would it make sense for me to try it out for a year and apply for IB options outside of JPM (I do not have a problem in losing a year in this process)
