+pct mount $1 # number of LXC CTR

+
+First, mount the LXC filesystems on the Proxmox host (LXC does not need to
+be running, but can be).  Use `pct mount xxx` for each LXC.  It will tell
+you the mount point, but it will be /var/lib/lxc/xxx/rootfs.  Now you can
+manipulate the files in the LXC from the Proxmox host.  This includes all
+mount points of the LXC overlaid properly.
+
+Next, use `rsync` to copy the files from one LXC to another using the full
+path to both rootfs`s.
+
+Finally, recursively chown the files with a uid/gid offset of 100000 (the
+offset used by unprivilaged LXCs).  Root in the container (uid 0) is uid
+100000 on host.  I would just `chown -R 100000:100000` the entire directory
+you just copied, so it`s accessible as root in the container, and then go
+into the container and fix permissions within the container as container
+root (using `chown -R user:group`)
+
+When you are done, `pct unmount xxx`.
