Came to ask exactly this

, have a nice P fare on SAS PLUS for OSL>MIA, which yields 150% to A3 program, minimum bid is 270 Euros, which I would gladly pay, if mileage earning would stay the same...
UPDATE: Called SAS hotline regarding this, agent was very helpful and checked the information, and quote, "
when bidding for an upgrade, the booking class stays the same, only the service class changes, so miles should be earned according the original booked fare"
