Is this a one time thing that you need to do or is it continuous? If it's a one time thing, why not just dump one database and import it into the other? If continuous, why not enable replication? You could also use the REPLACE() query, which will UPDATE if the row exists and INSERT if it doesn't. Also, if you remove your indexes while you INSERT a bunch of data and then rebuild them afterwards, it'll be faster.
