The run command above will store your data in internal Docker volumes. If you prefer to bind mount directories on your file system, then you can use the `-v` parameter, for example:
When running the container you can specify version to download from docker registry by using couple provided tags like *stable* which contains current stable release (this is generaly the same as *latest*) or *oldstable*. You can also use specific version like *2016-06-26a*.
Just stop the old container and run the new one with the same `-v` mapping. Since the data is on your file system, you do not need to do anything special to preserve it between containers.
