UPGRADE
~~~~~~~
**upgrade** {--to *version* | --resume}
This command safely switches all nodes of the cluster to a new Ganeti
version. It is a prerequisite that the new version is already installed,
albeit not activated, on all nodes; this requisite is checked before any
actions are done.
If called with the ``--resume`` option, any pending upgrade is
continued, that was interrupted by a power failure or similar on
master. (This option is not yet implemented.)
