I am considering leaving Xero and migrating to Xero however I do not see an viable way to migrate without loosing historical data.  Such as After you transfer the 4 items you mentioned Customers, Vendors, Accounts and Products and Services, I will need al lot more data transferred.  Such as customers,,,, where are all the invoices that are connected to each customer, what invoices are paid vs not paid, All my Account Receivables?  I need to migrate 5 years worth of customers, invoices, transactions, chat of accounts, GL,  AR, AP, Expense reports, copies of receipts, copies of invoices,financial statement, balance sheets, fixed assets, expenses, income, etc. 

Can someone let me know if they have actually migrated all their data successfully from Xero to QBO.  If so how?  I am trying to build a plan before I begin migration.  I just cant afford to loose all my Xero data.

Thanks Mike,
