Thank you so much @smoove, I totally forgot to do this on the server for my own sake! Well the reason is, I am really looking at a long-term solution, not just for this Japan address job.
This desktop app technique I am using now is more geared towards my clients who cannot do that command/code (you are recommending) themselves. I am looking at how to do this kind of migration and synchronization of local and online (MySQL) databases automatically (or at least with a single click by my clients). My clients may not even know how to do FTP; even if I provide them with manuals to the technical steps, they might find it difficult. That’s why I am building these VB.NET migration/synchronization utilities that do flat-file migration and local-to-online (Intranet-to-Internet) table synchronization so that they can accomplish the task on their own.
I can setup MySQL Replication but they will have problem with primary IDs. Aside from that, I don’t know other tools/technique out there that can do these migration and synchronization.
