Trying to swap an Intel 386SX-16 for a Cyrix Cx486SLC2-50 processor

Last weekend we opened up some computers and found some nastiness, one of which was a 386SX with a little bit of corrosion:

Yesterday, we found that the board works after a cleanup:

Let's see if we can unsolder the CPU from the previously battery-damaged (but cute) Cyrix Cx486SLC2-50 processor motherboard:

and transfer it to the 386sx board.
