Copy data from NAV 4.0 to NAV 20133

Lion

Hello

I must copy data for 300 tables from NAV 4.0 to NAV 2103. Earlier I used dataports, now I try use XML ports but it is to slow. To generate XML port I need 1 hour per table (to generate dataport I need 10 minutes per table). In dataports I used "Field menu" button and paste all fields in one move. I cant do it in XML ports. Do you have any idea how can I generate XMLport faster?

Thanks for any help
