The easy way

If the op-amp you're de-soldering from the board is cheap, don't bother trying to salvage it. The NE5532 Duster removed, for example, sells for $1.01 each at Mouser. Hardly worth saving, even if you could. My experience has been that even if it isn't cheap, I've always managed to mangle it in the removal process anyway, when I tried to remove it intact.

I take a small pair of snips and cut the old op-amp out, as close to the body as I can. That leaves 8 "legs" soldered to the board.

Grab the legs with a needle-nose pliers, one at a time. Heat one leg while drawing it out with the pliers.

Once all eight have been removed, use a solder sucker or round wooden toothpick to open up the holes.

Install an 8 position, 2 row DIP socket, like the one linked below, in the circuit board. Solder it in, and then you can "op-amp roll" a whole lot easier.
