Xero keeps a detailed journal history for all operations. Because of the large volume of information on Customers/Suppliers level, the migration will merge journals related to Credits, Prepayments, and Overpayments in order to keep an accurate balance on all accounts. This means that older period reports might not represent the correct balance at that time even if all the current and outstanding balances are correct.
