When importing a docker image from another system you may run in to an error where the client version is newer than the server. The following is an example of this issue and how to fix it:
$ docker load -i ubuntu.tar
Error response from daemon: client and server don’t have same version (client : 1.23, server: 1.16)
$ boot2docker stop
$ boot2docker download
$ boot2docker up
Now you can run the load command again and it should work.
