will all the data transfer from QBO or QBD to Sage-50? Because in Sage-100 you lose a lot of data such as old invoices, old purchase orders, only financials, customers, and sku's come over.

Consider to convert your data to QB Desktop file and you can use the trial version to access your historical data for good. Then you may start from scratch in a new program to lower your conversion costs.
