Importing Vendor Master in Axapta 6.0

For our company, we are upgrading the axapta version from 4.0 to 6.0. Please can anyone guide me on how can I upload the vendor master though excel or csv file with the datas like vendor code, vendor name and the address.

Till now I have understood that in ‘DirPartyTable’, the vendor name is to be put and based upon it in the ‘VendTable’ the vendor code is to be updated. But how can I even associate the address to it?
