Exporting and Importing Millions records in HANA

Hi ,

I have around 1.5 million records in development system.

I want to transfer all those records in Performance System.

I tried by Exporting all records in .csv file and importing in Performance System but It resulted in some errors.

On cross checking , I found the .csv file contained some inconsistent data which is not in source system also.

I might be because file size exceed 2048MB which is not supported in Client Export.

Is there another way to transfer records in Performance System..?

Thanks and Regards,
