### Upgrading Notes
Upgrading to 1.4.0 and greater you must move or copy the files of user-docker's data-root otherwise your data will not be available:
```
#!/bin/bash
old_docker_root="/proc/1/root/var/lib/docker"
new_docker_root="/proc/1/root/var/lib/user-docker"
system-docker stop docker
cp -a $old_docker_root/* $new_docker_root
system-docker start docker
```
Upgrading to 1.4.0 and greater you must set `rancher.system_docker.bip` if you want to have another bridge IP of docker-sys:
```
$ sudo ros config set rancher.system_docker.bip 10.0.0.1/16
```
