I have two address book with similar contact records. When I transfer one to the other, it looks like that those with address changed in the source address book will be updated in the traget address book without creating any duplicated record. However, if a the salesperson's name is changed in the source address book, when I transfer into the target address book, I will create a NEW record (same company, address, but different salesperson name). Am I missing anything?

Thanks

Simon
