Crossgrade: eligible versions Logic & Ableton Live

Hello,
could someone, ideally an official Steinberg person, please give definite information regarding which versions of Logic Pro & Ableton Live are eligible for crossgrade price for Cubase Pro 10.
I would like to know if Live 5 or Logic Pro 9 are eligible?
I have searched this forum, the steinberg website & shop, and more widely and cannot find any info.

It might be helpful for others if the answer provides the oldest eligible versions of all the software mentioned here:

Thank you
