I think '08 amd '09 uses the same sensor. 2010, '11, ,'12 use a different sensor. So if TPMS worked prior and you had them moved over and aired up properly, the TPMS light should stay off. If the new wheels did'nt have TPMS or it's a different year (like 2010 putting tpms tires/wheels on an '08), your alarm is going to go off. Look at the valve stems on the old set of rims and new installed set.
