Join Plaster & Drywall

The bathroom I renovate had all the walls covered with ceramics up to about 4 feet from the floor. The ceramics were all glued to a concrete substrate with a wire mesh behind. The floor ceramics are the same. I have removed all ceramics and the concrete behind with an electric hammer and soon I will install new waterproof gyproc on the walls and cement board around the bathtub. My question is how should I do the joints between the new gyproc / cement board and the existing plaster. The plaster is approx. 3/8 thicker than the gyproc and I plan to install shims on the studs to make up the difference. Would the regular gyproc all purpose mud with paper tape will stick to the plaster? Thank you.

I don't have much experience with plaster but taping it to the drywall should work. While I would probably use durabond I think j/c would be ok. Unless it is fit bad the durock shouldn't need to be taped to the plaster or the drywall.
