Need to Export / Import approx. 1Million records

Hi All,

I have to export a table data which contains approx. 1 Million records and need to be imported into another table (in other database) in NAV.

Is there any quick way to achieve it apart from creating XML Port.

As rapid start is not working in this case getting below issue:

Microsoft Dynamics NAV
---------------------------

SaveCopyAs method of Workbook class failed
---------------------------
OK
---------------------------

Thanks in advance
