Well, some claimed that it worked. Like, change sources lists, pin packages to version you want to downgrade to, apt-get update && apt-get upgrade, apt-get dist-upgrade and then purge misbehaving packages. And after that another dist-upgrade. But, not sure that it will work every time, never did it personally nor seen someone really doing it. Plus I do not understand need for that. Just backup your data, get selection of manually installed packages with apt-mark, or with aptitude, install Jessie and backup your data, then use apt-mark and apt-get to install those packages. It is much safer approach to solving that problem.
