The ticket is reissued with a new booking class, so I guess you should get more miles.

The new booking class can vary and seems to depend on the availability rather than on your original booking class. The easiest way to know for sure is to go to your reservation, select the flight you want to upgrade and start the process. It will immediately show you the new booking class on the next page, without having made any payment.
