You want to be careful when removing the top plate of the wall. It is probably attached to backing nailers, boards nailed from the top down into the very top plate of the wall (running parallel and overhanging 1-1/2"). Using force will jar/break the plaster on the many lath pieces of wood nailed up into the nailers, then plastered, of the existing ceiling. This will cause undue work and time. With the double top plate exposed and the wall removed, use a helper to support a 2-3' section of plate, starting on one end. The other person cuts the plate with a multi-tool or circular saw with eye,hand, sleeve protection, very carefully. I cut it into sections, remove the bigger ones that are not nailed. Cut the nailed ones small enough to use a sharp chisel, splitting from the end grain in the fastener line. Tap the nail up, add 1/2" drywall between the lath, tape and texture. Don't shock the lath/plaster. You may find the nailers are now floating in the joist cavity and need support. A whole 'nother ball game.......
