Roll Back Access 2013 app to Access 2007

I have an Access 2013 application that needs to be converted back to Access 2007. The application was originally in 2007. When trying to import the objects from 2013 to 2007, Access 2007 does not recognize the 2013 database. From 2013, I can export one object at a time, but this is very time consuming. In the 2013 database, I tried writing a function to export all objects at once, but it doesn't work. Below is that function. Any help with the function, or other ideas to roll back would be appreciated.

Function Export_2007()
DoCmd.TransferDatabase acExport, "Microsoft Access", , "c:\client_db\clients.accdb", , "C:\Users\Don\Documents\client_new.accdb", False
End Function
