Wow, that's some heavy stuff-
Can't you just remove the files you want with a USB, boot into
Ubuntu live CD or another, move and resize partitions using Gparted
and then install Lenny and then put your files back in?
tell us the output of "df -h" in a terminal on the partition you want to upgrade(the one your gonna erase).
Code:
bz@bz-desktop:~$ df -h
