As per my understanding he asked about the filesystem, correct me if I'm
wrong.


You can just copy files over to the new place.

A good method:

rsync --delete -rvalH --numeric-ids /var/lib/lxc/CONTAINER
dsthost:/var/lib/lxc/
lxc-stop -n CONTAINER
rsync --delete -rvalH --numeric-ids /var/lib/lxc/CONTAINER
dsthost:/var/lib/lxc/
ssh dsthost lxc-start -d -n CONTAINER
