Pins are glued, they won’t just come out. There are tools to remove those pins and you can basically make your own, it’s basically a thin flat piece of metal you shove into each channel to move the retaining tab out of the way temporarily

But again the adhesive will mean this won’t work unless you cut/remove it. Also are you sure the only thing that’s changed is the connector? The pinout may have changed, the board you’re connecting to may have changed, etc
