An account exchange system is provided by a data aggregation service enabled for gathering data for a subscriber from a data repository of a first financial institution, using account exchange software operating on a server coupled to the data aggregation service. Initiated by a subscriber the account exchange software causes an account to be terminated at the first financial institution and a new account to be opened at a second financial institution, using data from the first financial institution, and processing the data to be compatible with data requirements at the second financial institution.
