Replacing you while transitioning you into a new role means they basically end up with two new employees instead of one.
You should take their advice and easily get the job you want somewhere else.

I don't think my departure would be a good thing for them. I'm on a small team, and my leaving would greatly decrease their capacity.
I'm also being encouraged to take on more responsibility while I'm still around, so I'm not getting swept out the door or anything here,
Their capacity issues etc are not your problem. Your problem is how to get from where you are to where you want to be, if you're happy with more responsibility instead of a different role then stay.
