Yes, with new machines typically having many orders of magnitudes more
storage than old ones it is easier to keep a backup of old stuff
online than to sort through it.   If both machines are still running,
on the old one, cd to /, then
rsync -av . new_machine:/path/to/save
perhaps using --exclude to avoid the /proc and /sys directories.
Rsync will create the last directory in the target path if it doesn't
exist, but only the last one.
