Un-mounting and re-mounting bindings

Un-mounting and re-mounting Salomon Profile Skate bindings.
We recently bought a new pair of Atomic skis for my daughter and an
older pair of Peltonen skis with a nice pair of binding.
Can anyone advise me on taking the bindings off the old pair and
re-mounting them on the new pair?
I did the same thing with a pair of NNN bindings last year but the
seemed easier to dismantle without trashing them.

Thanks in advance.
