Thank you for all the responses to my question. Especially the information about updating the desktop version before exporting the files. There is a 3rd party that imports the files into QuickBooks on line for new account in SA but they are not able to tell me how to extract the files from the Desktop, or which files to extract. I am also concerned about the change over time frame. While waiting for the files to be uploaded to QuickBooks online the company would have to stop invoicing. I have to factor that interim period into the migration as well.
