From LimeSurvey Manual
The "Import a VV Survey File" screen needs you to choose the "vvexport" file you are importing. If you choose to "Exclude Record IDs" the records will be imported and brand new Record ID's will be generated for them (use this option for the use case "Adding new responses to the existing responses of a survey"). If you un-check this box, then the original record id's will be imported (use this option for the use case "Overwriting all responses of the survey").
