Moving Product Pricing Data Only Between Servers

Hi All

We're just about to migrate our client's store from staging to 'semi-live' (a subfolder on the clients host server), while we do some final testing.

In the meantime, 2Checkout have kindly informed my client (with minimal notice and only days after he signed up with them), that they will be no longer dealing with his currency due to a change of bank.

So we have to revert his site to Euros. No problem you might think - except that the client has just, despite two instructions from me detailing the location of the new server, changed the price on the old server! Clients, eh? !!!

So my question is: is there any way to move just the repriced product data (he has hundreds of products), quickly and easily from one place to the other?
